AI MIX
ENGINEER

Multiple tracks — that is the whole point. Load TonalBrain on each of your key tracks (kick, snare, hi-hat, bass, lead vocal, main instruments), up to 24 tracks for optimal accuracy. Each instance you add appears as a tab in the plugin, so you only need to keep one window open. When you click Analyze, the AI sees how all your tracks interact with each other and applies the right settings to each one.

Yes. Before you get suggestions, you can capture up to 4 sections of your song, 10 seconds each — for example the verse and the chorus. The AI considers the instruments, density, and dynamics of each captured section, then finds EQ, compression, and stereo settings that hold up across your whole arrangement. You get one mix for the whole song, for 1 credit: the settings do not change from section to section.

TonalBrain handles the corrective technical side of mixing, including EQ to fix frequency masking between instruments, compression thresholds, de-essing, stereo placement, tape saturation to glue your mix together, and harmonic excitement on the tracks that need air. Creative effects like reverb, delay, and spatial design are entirely yours to shape. Mixing is both art and technique. We take care of the technical decisions that require years of trained ears and deep knowledge of acoustics — so you can spend your time on what only you can do: the artistic choices that give your music its character.

TonalBrain is an AI-powered audio plugin that analyzes your entire multitrack session to provide intelligent mixing decisions. Unlike traditional plugins that process one track at a time, TonalBrain listens to all tracks simultaneously to identify frequency masking, dynamic collisions, and balance issues — then applies professional-grade processing across your entire mix, including EQ, compression, de-essing, stereo imaging, tape saturation, and harmonic excitement. It can also analyze different song sections so the result works across your whole arrangement, not just one moment of it.

Every track gets EQ and compression. On top of that, the AI builds a module chain from a de-esser, stereo width, a sidechain compressor, an optical compressor, analog tape saturation, and a harmonic exciter — choosing which modules that track needs and at what settings. Every module it adds is fully editable, removable, and reorderable afterwards.

Yes. TonalBrain is a VST plugin, available in the modern VST3 format, and also as an AU plugin and an AAX plugin. It loads as a VST in any DAW that supports VST plugins (Ableton Live, FL Studio, Cubase, Reaper, Studio One), as an AU in Logic Pro and GarageBand, and as AAX in Pro Tools.

TonalBrain is available in VST3, AU, and AAX formats, compatible with all major DAWs including Ableton Live, Logic Pro, Pro Tools, FL Studio, Cubase, Reaper, Studio One, and more.

TonalBrain runs on macOS 10.15 (Catalina) and later, natively on Apple silicon and Intel Macs, and on Windows 10 and Windows 11 (64-bit). There is no Linux version.

TonalBrain is designed to work with multitrack sessions for best results — it needs individual tracks to understand the full context. That said, you can use it on stem groups (like a drum bus) effectively. For stereo mastering of full mixes, we recommend a dedicated mastering tool.

New accounts get 3 free credits, added automatically the first time you sign in to the plugin in your DAW, with no credit card required. After that, you buy a pass when you start a song: no subscription, nothing renews. Each pass gives about 50 credits for each month that it is valid, and each analysis costs 1 credit, for up to 24 tracks. When a pass ends, its unused credits end too, but the plugin and all its effects keep working: credits are only for new AI analyses. Buy any pass before it ends and your unused credits carry over.

There are three passes: Single ($9.99, 50 credits, 30 days), EP ($24.99, 150 credits, 90 days) and Album ($79, 600 credits, 12 months). The names are only a guide: you can use any pass on as many songs as you like. Nothing renews automatically.

Your TonalBrain account works across all your personal devices — there is no per-device activation limit. Just log in with your account on any machine you own and your credits are available everywhere.

Your raw audio never leaves your machine. TonalBrain analyzes the frequency and dynamic characteristics of your tracks locally, then sends that analysis data to our servers to calculate your mix settings. No audio files are uploaded — only the spectral data needed to make mixing decisions. We do not store or share your audio content or analysis data beyond processing your request.
