What it is

UnMixLabs is a web service and API that separates finished audio into vocal and instrumental stems. It accepts MP3, WAV, FLAC, M4A, OGG, MP4, and MKV files, with 4-stem, 6-stem, 53-stem, and vocal-isolation modes. Stem types include vocals, drums, bass, guitar, piano, other instruments, and instrumental. Each job includes BPM, musical-key, and chord-progression analysis. Optional processing offers vocal dereverb, stem-to-MIDI, beat-grid export, synced lyrics, karaoke video, and audio cleanup presets. Outputs can include WAV, MP3, FLAC, MIDI, beat-grid TSV, REAPER sessions, lyric SRT files, and karaoke MP4s. Batch processing is available, and Studio lists API access. The Free plan costs nothing, allows 10 processing minutes monthly, one 100 MB file at a time, 4-stem splits, and 24-hour retention. Pro is $10.99 a month; Studio is $24.99 a month. The pricing page says service is free-only during beta.
