Why can I still hear some vocals?

Reverb and backing vocals are often spread across the stereo field, so they are not cancelled. Studio recordings with a dry, centered lead vocal work best.

How Vocal Remover (Karaoke) works

It uses classic center-channel cancellation with the Web Audio API: sound that is identical in both channels (usually the lead vocal) is removed, and the bass is added back. It is not an AI stem splitter, so results depend on the mix.

Input: MP3, WAV, M4A, OGG, FLAC. Output: MP3, M4A, OGG, WAV.

Tips

WAV is lossless but large; MP3/AAC/OGG are compact for sharing.
Engines load on first use and are cached afterwards.
