BytePlus Voice and Background Audio Separation vs HitPaw Vocal Remover

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.

HitPaw Vocal Remover separates vocals and instrumental tracks from audio and video files using an AI algorithm. It is available for macOS, Windows, and the web. The desktop version supports more than 1,000 video and audio formats, including MP3, WAV, OGG, MOV, MP4, MKV, and AVI; processing takes place locally, so files remain on the user's PC.
