AIVoiceSeparator review
An affordable vocal-separation tool with useful analysis features and an asynchronous API.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AIVoiceSeparator is a browser-based AI tool for separating songs into vocal and instrumental stems. It is suited to karaoke users, creators, DJs, musicians, and developers building audio workflows. Users can upload audio files or submit supported media URLs from services including YouTube, SoundCloud, TikTok, Bandcamp, and Vimeo. The service supports audio and video inputs, with results available as MP3, WAV, or FLAC files.
Its strongest differentiator is the combination of separation and music metadata features. A three-model AI ensemble uses BS-Roformer, Mel-Roformer, and MDX23C for the stem-processing workflow. Optional lyric transcription can produce SRT, LRC, and TXT files, while BPM and musical key detection add useful context for remixing, practice, karaoke, and DJ preparation. The free plan includes Full Studio quality, all three export formats, lyric transcription, and BPM and key detection, making it suitable for occasional users who want more than basic vocal removal.
Pricing gives infrequent users a clear pay-as-you-go path: Credits cost $0.50 per song, have no subscription requirement, never expire, and charge only for successful separations. The Pro plan costs $30 per month and includes six songs per day, Full Studio quality, MP3, WAV, and FLAC output, and lyric transcription. Developers can connect through a REST API with asynchronous job polling, while automatic deletion of input and output files after 24 hours limits how long processed files remain available. AIVoiceSeparator fits users who need inexpensive vocal and instrumental separation with exports and metadata tools; it is less suitable for workflows requiring more than two stem types or files longer than 20 minutes.
