Getting started
MixMasterAI is an online repair, mixing and mastering platform. Upload a song, choose a sound, and create a release-ready master with genre-aware EQ, dynamics, stereo processing and loudness control.
Processing time depends on track length and device speed. The mastering screen shows each stage and its live progress.
WAV, MP3, FLAC, M4A, AIFF, AIF, OGG, and AAC files up to 200 MB. The finished master is prepared as a 24-bit WAV.
The main mastering uploader accepts files up to 200 MB.
You can upload, shape, process, and compare a master first. Downloading or exporting it needs an account with an active membership.
