AI Vocal Replacer
How do you replace the vocals in a song and keep the instrumental?
Upload the full song or pick one from your library. AI separates the vocals from the instrumental, then sings your new lyrics in the voice and style you describe, for example "soft breathy female vocals", over the same backing track. You don't need to split stems in another app first. The new vocal is a fresh performance, so the melody may shift slightly. Each run gives you two versions in a few minutes, for 30 credits.

Same beat, new vocals
AI vocal replacer vs doing it by hand vs regenerating the song
The vocal replacer keeps your instrumental and does the separation and new vocals in one run. Doing it by hand needs two tools. Regenerating the song changes the instrumental too.

Replace the vocals without rebuilding the song
If you like the beat of a song but not the vocals, regenerating the whole track usually gives you a different instrumental too. Doing it by hand means separating the stems in one tool, then uploading the instrumental to another to add new vocals.
This vocal replacer does both in one run. It separates the vocals from the instrumental, then sings your lyrics with the singer you describe over the same backing track. The drums, bass, chords and arrangement stay; the vocal is new.
The new vocal is a fresh performance, so the melody may shift slightly. To keep the original singer and melody and re-sing only a 10 to 60 second section with new words, use Change Song Lyrics. If you only have an instrumental, use Add Vocals to Instrumental.
AI vocal replacer FAQ
Yes. The vocals are separated from the instrumental, and the new vocals are sung over that same backing track. On busy mixes a faint trace of the old voice can remain, because the separation is done by AI.
No. The AI sings a fresh performance in the style you describe, so the melody and phrasing may shift slightly. You can keep the same lyrics and describe a new singer, but it isn't a same-melody voice swap. To keep the original singer and melody, use Change Song Lyrics on a 10 to 60 second section.
Yes. Songs picked from your library come with their lyrics filled in; leave them as they are, describe the new singer and generate. For a song you upload from your device, paste its lyrics into the box first.
30 credits per run, and each run returns two versions. Free accounts get 50 credits every month with no subscription, enough for one run a month. If a run fails, all 30 credits are refunded automatically.
A song with vocals that you have the rights to: your own recording or an AI song you made here or in another tool. MP3, WAV, OGG, M4A or AAC, up to 50MB and 8 minutes. FLAC isn't supported.
Yes, if the song is yours. Download the audio from Suno and upload it here. One run costs 30 credits and returns two versions, and free accounts get 50 credits a month with no subscription. On Suno, the Get Stems plus Add Vocals workflow needs a Pro or Premier plan.
No. Use Add Vocals to Instrumental: it skips the separation step and goes straight to singing over your beat.
Not if it matches a released recording: those uploads are blocked by copyright checks, and you aren't charged for a blocked run. Use songs you wrote, recorded or generated yourself.
Results made from songs you created on RaoMusic, or from your own original songs that you upload, can be used commercially, even on the free plan. Subscribers can also download a commercial license certificate.
