Bandmixr

Bandmixr offers AI mixing and mastering from stems. Users upload multitrack stems (vocals, guitars, drums, bass and more, up to 24 stems), choose a genre, and receive an automatically generated mix that can be fine-tuned for volume, panning, and effects. Users can also master an existing mix with Streaming, Standard, or Loud presets, or with a reference track. Free browser-based tools include a Mix Analyzer for loudness, true peak, clipping, stereo, and tonal balance checks, and a Rehearsal Cutter that splits long recordings into individual songs. The page states that users own their music, that files are not shared or used to train machine-learning models, and that deleted files are permanently removed.
