Upload a song to the server and create a download link of the processed song that vocal tracks are reduced and instrumental tracks are intact. The quality depends heavily on the type of song, and so use the app with discretion. In many cases, it will be good enough.
Audio and video file types such as mp3 (audio), mp4 (video), m4a (mp4 audio only) are supported. Other types work if the audio track is compatible.
Uploading is queued and processed in turn. Vocal removing takes some time. Relax and Enjoy!
