How AI builds backing music around your voice
Singers use it to hear a song idea with a full arrangement, songwriters use it to turn a voice memo into a full song (voice to song AI), and a cappella performers use it to try the same vocal in different genres. Because you can upload your own file, the vocal does not have to come from RaoMusic.
The AI listens to the melody, timing and phrasing of your vocal and writes an arrangement that fits it in the style you describe. The result is a new render of the whole track, so your vocal stays at the center while the music is built around it.
For the best result, upload a clean vocal with little background noise or music, sung in steady time. Be specific in the style field about genre and instruments. If a take doesn't fit, change the style and generate again; each run gives you two versions to compare.
