BytePlus Voice and Background Audio Separation vs PhonicMind

BytePlus Voice and Background Audio Separation is an API service that processes audio or video files into vocal and background tracks. Drama and Narrate scenes can further separate vocals, music and sound effects. BytePlus lists video editing, vocal enhancement, video translation and voice cloning, and ASR optimization as use cases. Requests create asynchronous separation tasks, checked through polling or event notifications. Inputs must be publicly accessible HTTP or HTTPS URLs, with MP4, FLV, TS, AVI, MOV, WMV, MKV, MP3, M4A and WAV supported. Outputs can be AAC, MP3, WAV, M4A or FLAC, with AAC as the default; result URLs remain valid for 24 hours. The listed plan costs $0.01 as a one-time purchase, billed per minute of input source duration. Storage and VOD CDN distribution may add fees. The service is available through API, Linux, macOS and web, with Console, CLI and OpenAPI deployment methods.

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.
