Sonura vs UnMixLabs

Sonura is an artist-led AI music studio for making loops, vocals, one-shots, stems, and full tracks in a browser or DAW. Its Sonura Split tool separates an uploaded mixed track into vocals and instrumental, or into six stems: vocals, drums, bass, guitar, piano, and other. It accepts WAV or MP3 uploads and returns stems in either format. Sonura says most tracks finish in under a minute, while longer files and six-stem splits can take a few minutes; processing runs on its machines. The page directs users to check the app for the current file-size limit but does not state the limit. For DAWs, Sonura Flow is a VST3 and AU plugin for Ableton Live, Logic Pro, FL Studio, Studio One, Bitwig, Cubase, Reaper, and GarageBand. It is available for macOS 12 Monterey or later and 64-bit Windows 10 or 11, and needs an internet connection while creating sounds. Sonura says stem splitting is cleared for commercial use if users own or have permission to use the recording. The free plan includes daily creation allowances; paid plans start at $20/mo.

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.
