What BytePlus Voice and Background Audio Separation is
BytePlus Voice and Background Audio Separation processes audio or video and returns vocal and background audio tracks. For Drama and Narrate scenes, it can separate vocals, music, and sound effects into three tracks. BytePlus lists video editing, vocal enhancement, video translation and voice cloning, and ASR optimization as possible uses. The API submits an asynchronous job; completion can be checked by polling or event notification. The guide accepts publicly accessible HTTP or HTTPS URLs and lists MP4, FLV, TS, AVI, MOV, WMV, MKV, MP3, M4A, and WAV inputs. Outputs include AAC, MP3, WAV, M4A, and FLAC, with AAC as the default; result URLs remain valid for 24 hours. The listed plan costs $0.01, paid once, billed per minute of input source file duration. Storage and VOD CDN distribution may bring additional fees. The service is listed for API, Linux, macOS, and web, and its maker launched in March 2021.
