How can I remove background music from a clip using AI?

There are many so far that do this automatically like everyone here said, but you really would need some master to master the final audio, so I really recommend you to make some research after you have the isolated vocals or instrumental to enhance your file or song. 

Do not hesitate on write back if you need something else, thank you and I wish you a great Christmas

To remove background music from a clip using AI, I typically use tools like Adobe Speech Enhancement or LALAL.AI. These tools use machine learning to separate vocal tracks from background music, allowing you to isolate the speech more effectively. Simply upload your audio to one of these platforms, select the "Vocal" or "Speech" enhancement option, and it will separate the voice from the background music for a cleaner result.

Many sites are offering this service; one of them I have used personally is "vocalremover.org.".

It will provide you back the isolated tracks. 

You can do this for 1 track per day, a maximum of 10 minutes. 

If the background music doesn't have any vocals, you can use a website used Fadr to separate the music from the voice for example. But if it's going to be complicated if sound effects are involved because it can think that is the drums or percussion. Still a good tool to try regardless.

At this point I would not use AI. I love to have audio signal under control... I would use RX or something similar... all depends on audio material I work on...
