In their own words
AIVoiceSeparator
AIVoiceSeparator separates songs into vocal and instrumental stems for backing tracks or clean vocals. Its Studio pipeline combines BS-Roformer, Mel-Roformer, and MDX23C, then applies EBU-R128 loudness normalization. The maker reports an SDR of 12.97 dB and says this is roughly 3 dB above the open Demucs baseline. The web app accepts audio and video files up to 100 MB and 20 minutes in formats including MP3, WAV, M4A, FLAC, OGG, WebM, Opus, and MP4/MOV. You can submit YouTube or SoundCloud links; TikTok clips must be saved and uploaded. Optional Whisper transcription returns SRT, LRC, and TXT files and adds about 30 seconds to processing. A REST API accepts a URL or upload and returns both stems. The free plan allows three songs per month when signed in; pay-as-you-go credits cost $0.50. The maker says uploads and results are deleted within 24 hours and audio is not used to train AI models.
BytePlus Voice and Background Audio Separation
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.
