Soundtrap, from Spotify, is a browser production studio built to create and collaborate in real time: instruments, loops, recording and a stem splitter. MixingMusic.AI is the next step: it takes your already recorded tracks and mixes and masters them with AI.
They work in sequence: create and record in Soundtrap, then export and finish the mix and master in MixingMusic.AI.
