BytePlus Voice and Background Audio Separation
Singapore
What it is
BytePlus Voice and Background Audio Separation processes an audio or video file into vocal and background tracks. Drama and Narrate scenes can separate vocals, music, and sound effects into three tracks. Listed applications include video editing, vocal enhancement, video translation and voice cloning, and ASR optimization. The API submits an asynchronous task that you can monitor by polling or event notification. Inputs must be publicly accessible HTTP or HTTPS URLs and can use MP4, FLV, TS, AVI, MOV, WMV, MKV, MP3, M4A, or WAV. Outputs include AAC, MP3, WAV, M4A, and FLAC, with AAC as default; download URLs remain valid for 24 hours. Pricing is $0.01, paid once, billed per minute of source duration. Storage and distribution may add VOD fees. The service supports API, Linux, macOS, and web.
