As a teenager, I loved the Music Minus One records that my piano teacher introduced me to at the time: they were orchestral recordings of famous classical works that lacked the piano.

A piano score was also included.

So you could put on the record and – provided you had practiced diligently – take on the role of pianist.

Karaoke, invented in Japan in the 1970s, was and is commercially much more successful – here you slip into the role of the singer.

The thing has a drawback: the "voiceless" music productions used in karaoke often sound cheap and are made carelessly.

However, this can be changed thanks to artificial intelligence: On the website https://vocalremover.org/ you can have the voice “recalculated” from original hits.

For this it is necessary to have saved the corresponding songs as a file.

Then just click the "Browse my files" button and upload the music file of your choice.

After a little bit of arithmetic, the website will show you two audio tracks: the upper one contains the music without the vocals, the lower one just the vocals, which you can add steplessly.

In the left navigation bar you will find other nice tools to play with your song: You can transpose existing pieces of music (Pitch Changer), change the speed (Tempo Changer),
