Demixr vs PhonicMind

Demixr is a web service for processing audio, with tools for separating vocals and instruments, removing reverb, marking speech, and analyzing BPM and key. Its Pro 1.5 vocal separation has Voice mode for complex mixes, live recordings, or speech over music, and Music mode for songs and covers or separating vocals from accompaniment. A separate stem tool uses Demucs to split music into vocals, drums, bass, and other parts. For dereverb, Demixr recommends isolating vocals first; applying the effect to a mixed track can cause artifacts or distortion. VAD provides editable speech-segment markers and batch export, though detection may be inaccurate with quiet vocals or noisy recordings. BPM analysis includes tempo, key, and Camelot values, with optional tap-to-sync. The free plan costs nothing and includes 10 minutes of audio monthly, a 10 MB upload limit, two VAD uses, queued processing, and no WAV downloads. Paid one-time plans start at $4/mo, without automatic renewal. Uploads and outputs are deleted within 24 hours by default.

PhonicMind is a browser-based service for removing vocals and separating songs into stems. Its V.2.0 analysis examines a complete track, identifies vocal layers and instrument groups, and separates them in one pass. The service says it can recognize up to 16 stem classes and produce up to eight usable stems plus a metronome, depending on the song and tier. Stem categories include lead and backing vocals, instrumental, drums, percussion, bass, guitars, keys, strings, and horns. The browser player provides synchronized lyrics, chords, tempo detection, metronome, mixer controls, and stem playback. Uses include karaoke, acapella extraction, instrumental creation, practice, arrangement study, and remixing. Uploads accept MP3, AAC, WMA, FLAC, WAV, and AIFF files up to 100 MB. Plans range from a 6.99 USD one-time conversion to monthly tiers at 9.99, 18.99, and $29.99 a month.
