Balancing the low-end is one of the hardest challenges in any mix or master. BASSROOM is a final mix and mastering EQ that helps beginners and pros nail their low-end in seconds.

The Struggle Is Over

Balancing the low-end is one of the hardest challenges in any mix or master. This is where so many potentially awesome tracks fail. Too much bass and your track will sound bloated and lack clarity. Not enough bass and your track will sound weak.

BASSROOM is a final mix and mastering EQ that helps beginners and pros nail their low-end in seconds. It does this by delivering exceptional sound quality and suggesting genre-specific EQ adjustments a great audio engineer in a world-class studio would make.

We analyzed the best mixes in various genres to give you EQ target presets you can trust. You can also create your own targets with BASSROOM's inbuilt analysis tools. From this starting point, you can tweak your low-end to perfection using the immersive 3D room interface.

How To Use BASSROOM

Master Channel

BASSROOM uses complex algorithms that accurately identifies how the human ear perceives low-frequencies relative to the balance of the whole mix. For that reason it should be loaded on your master channel so it can analyse and be applied to your whole mix.

Choose A Preset

To get the most value from BASSROOM, start by selecting a preset that best suits the material you’re working on.

Create A Target

Alternatively, you can create your own target values by clicking the target icon in the bottom left corner and importing reference tracks. If you’re creating targets, we recommend clicking and dragging on the waveform to select the drop or chorus for the analysis, as this is usually the material with the best representation of the bass in the track. BASSROOM will create targets based on all the tracks loaded into the analysis window.

Shape your low-end

Now monitor a bass heavy section of your production (i.e. the drop or chorus), and you’ll see the targets move to the suggested EQ positions based on the tonal balance of your mix compared to the tonal balance of your preset. Use the targets to get a great starting point, then adjust by ear to tweak your low-end to perfection. The algorithm accounts for differences in loudness, so the targets will be accurate and relevant whether you’re mixing or mastering.

Level Match

The EQ adjustments may have changed the overall gain of your audio. If the gain has changed by more than 2dB the speaker icon will turn orange. Hover your mouse over the bypass icon to open the output gain and level match pointer. Match the gain slider to the level match pointer to match the perceived loudness of your audio before it passed through BASSROOM.

Hear The Difference

Not only will your low-end fall into place, but the level matching will give you a well balanced sound across the whole frequency spectrum. Toggle bypass on and off to hear the difference.

Unique Features

Unparalleled EQ Quality

BASSROOM gives you unparalleled EQ quality when working with low-frequencies on your master channel. Other EQs can introduce transient ringing and smearing or phase distortion that reduces the quality and clarity of your audio.

BASSROOM has specifically designed filters that have minimal phase distortion AND minimal transient distortion providing greater transparency than standard linear-phase filters at low-frequencies. This means that the low-end is not affected by unwanted phase changes that can alter the timbre of your audio or by transient distortion that means you lose the bite from kicks or bass-lines.

For example, the plots show the transient effects on a step function when applying a 6dB gain at 240Hz. Think of this as a simplified waveform of a kick drum. It's clear that the output of the filter in Plot 2 has an oscillation before and after the "hit". This is a "ringing" of the transient and can sound like a sucking effect. In Plot 3 BASSROOM’s EQ produces virtually no oscillation and so the transient is preserved.

With BASSROOM, you can transparently shape your low-end without compromising the clarity of your mix or master. This translates into retaining punch in the low-mids, and definition in the low-end compared to other EQs.

Immersive 3D Room Display

Ordinary EQs use a horizontal representation of frequencies and vertical representation of gain. BASSROOM takes a unique approach and focuses more on how we experience audio in the real world. Louder sounds feel closer while quieter sounds feel further away and lower frequencies are associated with a ‘foundation’ whilst higher frequencies are perceived as ‘air.

To reflect this, in BASSROOM frequencies are displayed vertically, and gain is represented by depth in the room.

When a band is on the central 0dB line in the middle of the room, there is no gain adjustment. Push frequency bands back in the room to decrease gain, and bring them forward to increase gain.

The unique and intuitive UI helps you visualise how you’re adjusting the low-end of your song. This gives you a more immersive mixing experience, helping you connect more with your music.

EQ Targets You Can Trust

The targets on the walls of BASSROOM suggest the genre-specific EQ adjustments a great audio engineer in a world-class studio would make.

We analysed the best mixes in various genres to give you EQ target presets you can trust.

This isn’t simple ‘slowed-down’ frequency matching. The targets are a result of a complex algorithm that accurately identifies how the human ear perceives low-frequencies relative to the balance of the whole mix. BASSROOM analyses your mix and displays a target in each frequency band to help you make informed mixing decisions sonically relevant to your audio.

Matching the bands to target suggestions results in a clear and defined low-end that’s well balanced in the context of the whole mix. Use the targets to get a great starting point, then adjust by ear to tweak your low-end to perfection.

Stay on top of Correlation

A multiband correlation meter with essential metering and monitoring functions.

Can You Relate?

Why the heck do you need a multiband correlation meter? It’s simply that a regular stereo correlation meter doesn´t always show you trouble spots. If your fat kick and bass is mono, it’s mostly correlated so a stereo correlation meter would show that everything is O.K. while your strings, hi-hat, or vocals are cancelling out! 2BC multiCORR combines the useful and beloved functions of our free 2BusControl monitor controller plugin with a carefully designed, third octave multiband correlation meter. Our multiband approach warns you not to overdo stereo spread with your fancy spreading tool, or when your stereo mics are delivering a signal with too much out–of–phase content. Either way, you’d get cancellation when your mix is summed to mono.

Correlation measures the degree of relatedness between left and right channel. If they’re alike, that’s mono, and they will have perfect correlation. Stereo noise is decorrelated, with no similarity between channels. Stereo music should be more like the former, with a bit of “stereoness” to create a soundstage, whereas convincing, diffuse reverb should have lower inter-channel correlation. When content is present in one channel, and an inverted phase version is in the other channel, that sums to zero in mono and the audio disappears.

Unobtrusive Power

2BC multiCORR’s powerful features hide behind its clean and simple UI. We’ve brought essential functionality and innovative user interface design to what used to be an unremarkable product category. With five monitoring modes, an ergonomic and deceptively simple interface, highly tuned correlation metering over 31 bands plus stereo balance and correlation, you’ve got to try 2BC multiCORR for yourself.

Better By Design

Most correlation meters use a cosine scale, derived from old analog meters, while 2BC multiCORR employs a trueLinear™ scale. This linear scale better matches your perception. As with all of MAAT’s products, 2BCmC follows our guidelines for creating meaningful tools for modern engineers.

2BC multiCORR combines essential metering and monitor controls with a 31 band correlation meter group.

Details

• 31 bands of correlation with carefully chosen centre frequencies
• Exclusive trueLinear™ scale for higher precision with visuals that match your perception
• Stereo Balance and Correlation
• Five essential monitor controls: Left–Only, Right–Only, Mono (L+R), Diff (L-R) and Flip
• Collapsable UI lets you see only what you need

Extras

• Includes a native version that runs in standalone mode, great for dedicated metering
• Plug–in runs on all major DAWs: AAX, AU, VST 2 & VST 3

Applications

2BC multiCORR is a general purpose tool for both production and post. Use its powerful metering and monitor controls for:

• Tracking and Mixing
• Mastering and Remastering
• Sound & EFX Libraries
• Radio & Television Production & Broadcast
• Identifying Problem Elements; EFX, panning, widening or frequency ranges that may compromise playback or downstream processes
• Verifying: balance, panning, super stereo processing and other creative decisions

Essentials

2BC multiCORR slots into all modern workflows:

• Supports LPCM sample rates up to 384k for DSD and high–end postproduction
• All standard formats: AU, VST 2 and 3, AAX
• Compatible with macOS and Windows
• Low fatigue visual design
• Resizable user interface for every screen resolution

The Low Down

If your material is destined for LP distribution, keep in mind that lacquer cutting has difficulty with large amplitude, out–of–phase information at very low frequencies. 2BC multiCORR provides four bands of analysis for the critical bottom octave, six additional bands of metering covering frequencies up to 200 Hz, plus three additional bands for the 200 to 400 Hz range.
Other than vinyl, why should you care about mono? Monaural playback is more prevalent than ever, with the rise of battery–powered, hand-held party speakers and the seemingly ubiquitous “smart speaker.” Don’t forget that Center Channel speaker in a surround setup…Though a product may advertise stereo playback, the simple fact is that size matters. At low frequencies, playback from any single point, diminutive device is essentially monaural. Also, small sources usually cannot reproduce the bottom octave at all and many begin to roll off below 100 Hz. So make sure to maximize the appropriate amount of LF energy for the material you’re working on.

Not Just Correlation

2BC multiCORR isn’t just multiband correlation. It also includes a left/right balance meter, a broadband left/right correlation meter, plus five monitor controls allowing you to focus on any issues you may come across.

With a single button, you can switch to Left–Only or Right–Only, Mono (L+R) or Difference (L-R). The fifth monitor control, FLIP, swaps the left and right channels. Sometimes you may come across a subtle issue that you think may be in one channel or the other. The Flip control, along with the Left–Only/Right–Only buttons, quickly helps to confirm or identify any problems. Also, you may occasionally be presented with a mix that’s not laid out from the audience perspective, and Flip is a quick way to rotate the soundstage around to where you’re comfortable.

Don’t Hit The Chair Without It!

2BC multiCORR packs the advanced features you need into one resizable window that’s easy on the eyes. Not only does the UI “get out of the way” so you can be more productive, but we’ve also incorporated user-centric features that speed your workflow. Easy and intuitive to use, be sure to hang it off the last slot in your Master Bus so you always know exactly what’s going on with your mix!

Key Features

• 31 bands of correlation with carefully chosen center frequencies
• Exclusive trueLinear™ scale for higher precision with visuals that match your perception
• Stereo Balance and Correlation
• Five essential monitor controls: Left–Only, Right–Only, Mono (L+R), Diff (L-R) and Flip
• Collapsable UI lets you see only what you need

BUTE Loudness Suite 2 is a smart, integrated and responsive loudness metering and audio limiting plugin that delivers the tools studios, media and broadcasting producers need to mix and master professional audio within loudness specifications.

What Does BUTE Do?

Many producers are moving towards mixing and mastering within loudness specs set internally or by major streaming and broadcasting platforms for quality assurance. By providing metering and limiting functions in the same plugin with smart workflow features to maintain creative flow, BUTE helps optimise the quality of mixes and masters, while avoiding potential distortions downstream.

Smart, Synchronised Workflow For Broadcasting, Post and Games

Loudness metering tools are ideal for balancing music, dialogue and sound effects whether in stereo or up to Atmos 7.1.2 surround sound. Long-form content is made much easier to deal with using our smart history overview. Get an overview of up to 10-hours of content and navigate to any section of a track with ease using the interactive display. BUTE’s custom alert system will clearly point out areas where there are errors with True Peak overshoots. A wide array of industry-standard presets are included.

Mixing And Mastering With BUTE

BUTE plugins are compatible with VST, AU and AAX (including Audio Suite), so will synchronise harmoniously with almost any DAW. Signum Audio's smart auto re-metering feature gives instantaneous feedback on how loudness will be affected by changes to the mix so there is no need to re-meter the whole mix. Readings for Absolute/Relative Scale, True Peak/LUFS and Max/Live modes are easy to toggle between from the main display.

Powerful Compact Read-Out View

When screen estate and CPU are at a premium, a compact read-out helps keep things optimised. BUTE is completely resizable. Even while in compact view, easily switch between display settings and tweak limiting configurations, while saving screen estate for other programs.

Stay Faithful To Your Mix

Smooth out peaks by adjusting pre-gain and selecting a preset release curve - Transparent, Natural or Smooth - which have been designed to make gain reduction as un-noticeable as possible. The release time configures automatically based on multiple properties of the input signal, and the dial is used to set the multiplication factor of the calculated release time, enabling fine-tuning. BUTE can also be utilised as a maximiser to push quieter mixes louder whilst taking care of True Peak overshoots. The result? The audio stays faithful to the original sound, whilst fitting the loudness spec of any platform.

Bring Your Music To All Streaming Platform

All the tools in your hand to make your music sound optimal on Spotify, YouTube, TIDAL, Apple Check and more. We regularly update presets and include most platforms. User-defined presets for internal standards can also be created and saved.

Acon Digital Mastering Suite consists of five plug-ins for audio mastering that were designed for ultimate signal transparency:

Equalize

Equalize is a parametric equalizer. Unlike other equalizers, you can freely adjust not only centre frequency, gain and bandwidths, but also the filter slope for each band. The filter slope can be set anywhere from 3 dB to ultra-sharp 120 dB per octave. You can operate Equalize as a zero latency plug-in when using the minimum phase mode, choose to preserve the phase relationships in the linear phase mode or use the unique mixed phase mode. The mixed phase mode allows you to set the latency freely in the range 5 to 120 milliseconds while preserving the phase relationships as far as possible. That gives a unique control over potential pre-ringing artifacts which is a common problem with linear phase filtering.

Learn more about Equalize.

Dynamics

Dynamics is a combined compressor, expander or gate. The look-ahead can be set anywhere from 0 to 30 milliseconds and the intelligent algorithm ensures a band-limited gain signal which reduces potential distortion to a minimum even with minimal attack and release times. You can use up to 4 times oversampling to further reduce distortion. The side chain signal can be either internal or external and there’s a full-blown side chain equalizer integrated with a low-cut, low shelf, peak, high shelf and high cut filters. The complexity of algorithms is not reflected in the intuitive user interface which provides graphical visualizations of all aspects of the processing.

Multiband Dynamics

Multiband Dynamics is the multiband extension of Dynamics which allows dynamic processing in up to four separate bands. You can freely set the cross-over frequencies and even the filter slopes can be set freely in the range 6 and 48 dB per octave. Multiband Dynamics operates in linear phase mode to avoid phase issues between the processed bands.

Limit

Limit is a transparent limiter with intelligent look-ahead in the range 0 to 30 milliseconds that reduces distortion to a minimum. The limiting is performed in a two-step process with a pre-compressor follower by the actual peak limiting algorithm. You can use up to 4 times oversampling for true peak limiting and to further reduce distortion.

Dither

Dither is a dithering plug-in with flexible perceptual noise shaping. You can adjust the maximum gain and the filter length of the frequency response of the noise shaping filter is visualized graphically.

Acon Digital Mastering Suite is available in 32 and 64-bit versions, as VST, VST3 or AAX for both Windows and OS X or as AU plug-ins for OS X.

Elevate Bundle

Mastering with a Brain

Elevate is the most advanced mastering plug-in ever created. This unique multi-band limiter, human-ear EQ and powerful audio maximizer will increase the loudness of your mix while maintaining or improving its dynamic perception. It uses intelligent, adaptive technology that responds in real time to your music; creating not only the loudest, but the best sounding master.

Developed by Newfangled Audio, Elevate maintains subtle dynamics and improves the tonal balance of your mix. The adaptive limiter analyzes 26 frequency bands and alters the gain, speed and transients for each band in real time. The result is a transparent, natural sound, no matter how hard you push it.

Elevate utilizes 26 critical filter bands modeled from the human ear. Each of the bands are spaced to give maximum control over how the sound hits your eardrum. Draw curves, solo bands and manipulate the transient attack for each individual band to bring out particular instruments such as kick or snare drums.

Adaptive Technology

Elevate uses artificial intelligence algorithms to make it easy for you to get the best sounds, but you can still get under the hood for as much precise control as you desire. This includes giving you control over the tonal balance and transients inside the final limiting stage. The adaptive algorithms reduce audible artefacts and the additional controls give you maximum flexibility with professional results.

Weiss MM-1: Loudness Done Right

Some brands become synonymous with their fields. They so revolutionise and define their product or process that true experts can’t see beyond them. When it comes to audio mastering, the one-and-only name is Weiss.

Based on the legendary Weiss DS1-MK3, the centerpiece of mastering studios the world over (and also now available as a Softube plug-in), the future of fast and professional mix maximizing is now here - the MM-1 Mastering Maximizer.

Featuring the very same algorithms as the original digital hardware unit, the MM-1 offers five flavours of limiting; Transparent, Loud, Punch, Wide, and De-ess; intelligently progressing as the ‘amount’ knob turns, and blendable with the mix control, to give users precisely the right amount of power over the feel of their masters.

Crucial to this plug-in is that it can’t sound bad - the intelligent processes happening under the hood as the amount knob turns; the filtering, compression, de-essing, and so on; have been carefully designed by highly experienced mastering engineers using the industry standard DS1-MK3 as a foundation.

And there’s no better mastering limiter out there. This product allows users to get their mixes exactly as loud as they want, with exactly the sound they want, without sacrificing dynamics and musicality.

In Short:

• Simple interface controlling detailed expert mastering processes.
• Five ‘flavours’ of limiting available.
• Contains the very same technology as the legendary hardware mastering processor, the Weiss MM-1.
• Fully licensed and endorsed by Daniel Weiss himself.
• Great for maximizing your mix-bus quickly and effectively.
• Go as loud as you want; louder than any other product out there; without sacrificing desirable tone and dynamics.
• Impossible to get it wrong. Be the master of your own masters!

The Gold Standard in Mastering

Mastering compression, limiting, and de-essing without compromise. Every mastering engineer’s fondest dream is about to come true. Softube's plug-in is a line-by-line code port of the legendary Weiss DS1-MK3 mastering processor — the unit no serious mastering engineer can do without.

The DS1-MK3 brings unparalleled mastering quality into the DAW-based studio with new features and workflows and makes the very best in mastering dynamics more affordable than ever.

Purchase of the DS1-MK3 also includes the intelligent Weiss MM-1 Mastering Maximizer plug-in, the Weiss Deess de-essing plug-in and the Weiss Compressor/Limiter plug-in.

Gold-Standard

Since its launch in the 1990s, the Weiss DS1 has become an absolute gold-standard unit, indispensable in mastering studios around the world despite a premium price tag. Its transparency, unparalleled versatility, and exceptional sound quality make it a must-have, heard (or rather not heard) on pretty much any major record you’d care to mention from the last twenty years. And in that time updates and improvements by Weiss have led to the near-perfection of the DS1-MK3.

And now for the first time ever, it is available as a plug-in from Softube, offering more flexibility than ever in a modern DAW environment, at a fraction of the cost.

What is the Weiss DS1-MK3?

This digital compressor/limiter/de-esser performs tasks no analogue unit ever could, across a wider range of settings. World-renowned mastering engineer, Bob Katz, author of Mastering Audio (hailed by Sound on Sound magazine as ‘the definitive work on mastering’), and three times Grammy winner, described the original hardware unit as ‘impeccable’, saying ‘it is the most transparent, refined, flexible, and least “digital-sounding” dynamics processor I have ever used.’

Working in collaboration with Weiss Digital Audio, this latest addition to the already rich and desirable Softube product range has been almost three years in development. Porting the code perfectly, line by line, from the original unit so that the plug-in sounds identical was just one task. Recreating the workflow and characteristic broad and usable functionality that made the Weiss such a legend was another.

Running at 32 bit/192 kHz (an upgrade on even the hardware original) the plug-in opens up the absolute pinnacle of sound quality to everyone. And with two all-new advanced limiter algorithms in addition to the Weiss original, nothing touches this processor for sheer excellence. Mastering like the masters is open to all for the first time, with all the loudness, clarity, and precision, and none of the drawbacks.

An Improvement on a Legend

The plug-in DS1-MK3 works at resolutions of up to 32 bit/192 kHz (an upgrade on the original hardware). And because it's a plug-in, you can run it on multiple tracks at once, at no extra cost.

De-ess your mids and sides independently. Compress with variable soft-knee settings to take you from gentle levelling all the way to aggressive crushing. And limit with simply the best, most transparent, brick wall available — including two all-new advanced limiter algorithms in addition to the Weiss original, the second of which is designed for true peak limiting.

Mastering for Today's Digital Music Services

Mix and Master for the listener - directly to Apple, Spotify, DAB Radio and TV specifications, MasterCheck will immediately reveal how your audio is going to sound to the listener, allowing you to produce with confidence and certainty.

Become Soundcloud Ready

*Now with SoundCloud and MP3 support!

Mix & Master For The Listener

MasterCheck is the complete optimisation solution for today’s delivery services, a plug-in providing the tools to make sure your music reaches the listener as intended. Streaming apps, download stores and podcasts all use data compression, loudness normalisation or both. These processes can affect your track in undesirable ways: your loud, punchy mix could end up quiet and flat, or suffer clipping and distortion.

MasterCheck reveals these problems ahead of time and enables you to deliver masters perfectly tuned for specific playout systems.

MasterCheck demonstrates the effects of loudness normalisation so you can find the sweet spot between perceived loudness and dynamics, and allows you to hear artefacts introduced by the encoding process ahead of time. You can quickly find the point where these processes will start to negatively impact the music, putting you back in control.

Audition Codecs

How do people listen to your output? You work hard to deliver masters that sound great at home, in the car or on earbuds, but that’s only half the story. How does your music sound on Spotify, Apple Music, Tidal, SoundCloud or YouTube?

All major online services encode your music, using different specs and formats depending on the playback device, the connection speed, or even whether the user is a “basic” or “premium” customer. Hot mixes can introduce True Peak overs that will clip on playback. MasterCheck detects these errors, and you’ll be able to hear obvious frequency masking and other artefacts. You can monitor the following codecs, with presets for specific streaming services:

• Ogg Vorbis
• FLAC
• Opus
• AAC-LC
• HE-AACv1 (AAC+)
• HE-AACv2 (DAB+)
• MP3

Reference & Comparison

Via the 'External ref' function, MasterCheck allows you to A/B with reference material in order to check differences in loudness, PLR and True Peak measurements. If you wish, you can use 'Offset to match' to match the loudness for a direct comparison.

'Offset to match' can also be used to remove loudness from an FX chain. This can be useful for evaluating the impact of signal processing, without being influenced by the 'feel-good factor' of increased loudness.

Flexible Workflow

With a resizable interface and many user-configurable options, MasterCheck can easily be adjusted to suit any situation. Dynamic colour splits for PLR can be set to indicate desirable ranges, and meter splits can be easily set to show 'safe zones' which indicate inter-sample peaks and so on.

For Mastering

Playout services essentially have a ‘letterbox’ through which they deliver your audio; if it doesn’t slide through then the service will force it to fit. A super-loud master might win the loudness war on CD, but will simply be turned down on any major streaming service. This leaves valuable headroom which you could have used for transient detail and punch.

It is important to be aware of how True Peak clipping can cause downstream distortion in encoded audio. Heavy compression will result in audible 'fizzing' and loss of stereo definition, especially with lower quality codecs.

For Mixing

The most popular streaming platforms now only differ by 3 LU between the loudest and quietest target for normalisation. Clearly, there is no benefit in mixing louder than the loudest platform, at which point all platforms will be turning down your audio.

Much of this is primarily a concern for the mastering engineer, but if you over-compress a mix then the mastering engineer has nowhere to go. If you compress above a platform's target level, transients lost cannot be regained at a later stage. Try using MasterCheck to audition at the service playout level to hear your mix in context.

RX Loudness Control supports offline processing as an AudioSuite plug-in for the two leading broadcast editing platforms: Avid Media Composer and Pro Tools 10-12. And for the first time, offline loudness-compliant processing is available as an audio extension for Adobe Premiere Pro.

Technical FAQs

How does RX Loudness Control process multiple channels of audio?

• RX Loudness Control applies the same gain envelope (linked operation) to all channels—for example, stereo and 5.1 surround—to maintain phase and balance between the different channels in the final mix file.

How does RX Loudness Control comply with different loudness standards?

• RX Loudness Control first analyzes the audio source file. Then it computes the amount of transparent correction required to hit the target without a perceived change to the dynamic range. The correction pass includes three elements:
  • A fixed amount of gain to hit the specified integrated loudness
  • [optional] An RMS compressor to limit the Short-term (or Momentary) loudness
  • A True Peak limiter
  • Steps 2 and 3 work only on an as-needed basis. If the audio signal already meets Short-term and True Peak specs, no extra processing is applied.

How does RX Loudness Control use compression?

• RX Loudness Control uses compression in a way that preserves the quality of your audio. When needed, a compressor dynamically and transparently adjusts your audio to ensure you get the best sound while remaining compliant. For loudness standards that require Short-term or Momentary compliance, the compressor is engaged automatically when loudness exceeds the specified target. You simply enable a slider via an on/off button and set the threshold. The Short-term/Momentary slider toggles between both modes, and can be turned on or off.

How will the processing affect the dynamics of my mix?

• For many mixes, dynamics are not affected at all. This is because only a fixed gain is required to meet the spec. However, if your mix is too dynamic or has significant transients, compression and/or limiting are required to meet Short-term (Momentary) or True Peak parts of the spec. This reduces the dynamics of the mix in the same manner as a compressor and/or iZotope's IRC™ II limiter (also found in iZotope's creative mastering platform, Ozone 6.).

Can my audio distort if my peaks are higher than the True Peak setting?

• IRC II is considered one of the best limiting algorithms. Its goal is to provide the best possible sound transparently during operation. For most mixes, it will only work occasionally to meet the loudness spec. If the limiter is being hit hard, it might be that the mix is too dynamic and needs to be redone or compressed prior to loudness correction.

What's the difference between RX Loudness Control and iZotope's Insight?

• RX Loudness Control and Insight complement each other in post and broadcast workflows. Insight is a surround sound, real-time loudness metering suite that helps you visualize changes made during mixing and mastering. RX Loudness Control is a more comprehensive tool that analyzes and corrects your final render for compliance with global loudness standards.

What is the difference between RX Loudness Control and the Loudness module in RX 4?

• RX Loudness Control includes several updates and enhancements that make it a more comprehensive tool than the Loudness module in RX. These include the following:
• Generate a loudness report in .CSV
• Supports surround sound, up to 5.1
• Available on the Adobe CC platform and as an Audiosuite DPM/AAX plug-in
• New, faster loudness algorithm (still with industry-leading accuracy)
• Supports the EBU R128 s1 standard

Will RX Loudness Control preserve the Left total/Right total (LtRt) encoding on a Dolby-encoded LtRt mix?

• Yes, RX Loudness Control will fully preserve your Dolby LtRt mix. Because the gain is applied consistently across all channels, the phase relationships and panning angles of your LtRt mix will be maintained.

Important Note: Tonal Balance Control 2 is included in Ozone 9 Advanced and Neutron 3 Advanced, and is now also available for separate purchase. Owners of Ozone 9 Advanced and Neutron 3 Advanced can update to the latest version of Tonal Balance Control 2 via iZotope Product Portal for free.

The non-directional nature of low frequencies can often contribute to a perceived lack of clarity and focus in the mix. Adding stereo FX processing and using multiple mic. set-ups in the studio can introduce phase inconsistencies leading to ‘weak’, ‘hollow’ or ‘flat’ sounds.

Monofilter lets you align and balance low frequencies with the minimum of effort, leaving you with the same sound, yet louder, more focussed and better defined. And with Monofilter you can be sure of great playback performance on systems with separate low-frequency handling, such as club PAs, live rigs, home cinema systems, HiFi, and 2.1 gaming systems.
