Question: Can you recommend a tool that allows me to remove background music from a song and keep the vocals?

The service lets you upload multiple files and accepts a variety of audio and video file formats, with fast processing and results that take seconds.

Another option is AudioShake. This AI-based audio separation tool isolates various elements of your recording, including vocals and instruments. It also has tools for mixing, mastering, localization and fan engagement, so it can be used in a variety of situations. AudioShake can handle high-quality audio files up to 192kHz, and you can try demos and free trials to see what it can do.

You can upload audio files and download the separated tracks without installing any software or signing up. Vocali.se is good for creating karaoke versions or isolating a particular audio element from a song.
