Audio Processing Help
Separate vocals and instrument tracks, create karaoke accompaniment and clean recordings online. Preview your results before downloading.
Upload, preview and download
Choose the tool for the output you need, upload the file, and sign in to submit. Check the displayed credit cost, wait for processing, then preview and download the results from your task page.
Choosing an input file
Use a source file you are allowed to process. Prefer a clean recording or lossless source; changing a compressed MP3 into WAV does not restore lost detail. Avoid clipping, and compare loud and quiet passages.
Limits and result quality
Upload MP3, WAV, FLAC, M4A or OGG within the displayed limits (currently 50 MB). Separation may leave bleed or artifacts. Keep a local copy of your results: server storage is temporary. Available download formats are shown for each task.
Trial credits and pricing
New accounts currently receive 10 trial credits. Processing consumes credits; additional credits are sold as one-time packs. Check the pricing page and task cost before submitting; the service is not unlimited free processing.
