Automix: AI-Powered Mixing for Musicians and Producers

In the fast-moving world of music production, achieving a polished, professional mix has traditionally required significant time, expertise, and access to costly plug-ins or studio environments. But what if there was a way to simplify the process while still delivering exceptional results? Enter Automix, the first-to-market AI music mixing tool.
Automix is designed to change how musicians and producers approach audio mixing. Using AI technology, Automix helps users create balanced mixes from multitrack audio in minutes, offering a streamlined solution for DIY music makers and producers.
What is Automix?
Automix is an AI-powered tool designed to handle the complexities of audio mixing, so that musicians and producers can focus on their artistry.
With Automix, you can:
Create professional-grade, balanced audio mixes in minutes without the need for a studio or advanced plugins.
Master your track for release on Spotify, Apple Music and all major streaming platforms, either with genre-based settings or by matching a reference track you choose. This works on Automix mixes and on finished stereo mixes you upload for mastering only.
Try the platform for free, then upgrade to download your mixes and masters in high-quality WAV, MP3 or FLAC. Options include Pay As You Go credits from $7.99 per track, or unlimited mixing and mastering with a Pro subscription.
Download your processed stems (Pro) to share parts with collaborators, or submit individual tracks for sync licensing opportunities.
Export your mix to your DAW (Pro) - send your Automix session to Ableton Live, Bitwig Studio, or Fender Studio as a Live Set or DAWproject file, so you can make your final creative touches with your own plugins and effects.
Automix Desktop (Beta) - Automix Pro subscribers can also use Automix Desktop (Beta) - the full AI mixing and mastering workflow running locally on your Mac or Windows PC. No uploads, no internet required, 2-5x faster than the web.
How It Works: Step by Step
Automix simplifies audio production with AI, making professional mixing accessible regardless of technical expertise or budget. Here's how to get started:
1. Upload your multitrack audio. Automix accepts audio stems in WAV format, processing each track individually while preserving overall balance.
2. Set your mix preferences. Select key parameters such as genre, desired panning and reverb to guide the mix. You can mix up to 32 audio tracks. If you have more audio files, create stem groups (drums, vocals, etc.) and combine them. You can also use our Audio Cleanup tool at this stage to remove unwanted noise and interference from your recordings.
3. Let the AI mix your tracks. Automix assesses your audio using algorithms informed by real-world mixing principles and professional engineering practices, applying level balancing, EQ, compression, panning, and spatial processing to each stem.
4. Preview and adjust. Listen to the results and tweak levels to suit your creative vision.
5. Download your mix. Within minutes, Automix delivers a balanced, studio-quality mix ready for release.
6. Master your track (optional). Choose a reference track you admire and Automix will match your master to its tone, loudness, dynamics and stereo width. Alternatively, let it optimise your master on its own, ready for consistent playback across streaming services, headphones and speakers.
Our tutorial walkthrough video below shows you how to set up a project in detail, including extra steps for creating stem groups (e.g. combining all drum stems into one mixed group first), a process that lets you mix more than 32 audio files in your Automix session.
Whether you're sharing creative ideas, refining a demo, or producing your debut album, Automix simplifies the complexities of music production - saving you time without sacrificing quality.
Can AI Master a Track to Match a Reference Track?
Yes. Reference Match in Automix takes a song you choose as a benchmark and shapes your master to match its tone, loudness, dynamics and stereo width. You can use it on a mix created in Automix, or upload a finished stereo mix and master it on its own.
Reference mastering is popular because it is far easier to point at a record and say "like that" than to describe a sound in technical terms. It works best when the reference shares a similar genre, arrangement and energy with your song, so treat it as a direction rather than a template.

How Does Automix Work Under the Hood?
Behind the scenes, Automix uses audio signal processing techniques combined with AI. The tool is built on research from Queen Mary University of London and incorporates training data curated by professional audio engineers following responsible practices. Over years of rigorous R&D and feedback from musicians and producers, Automix has been refined to deliver consistently strong results.
Unlike mastering-only tools that simply process a stereo file, Automix performs true multitrack mixing - analysing each individual stem and making independent decisions about EQ, compression, panning, level balancing, and reverb for every track in your session.
