Audimee

Demoing a song with the wrong singer, or paying a vocalist for every rough idea, adds up quickly. Audimee is an AI voice changer that converts one vocal recording into another voice using studio-quality models.

It also works as a vocal isolator and harmony maker.

The free plan gives you 15 minutes of conversions and 9 royalty-free voices, but it is limited to personal use, offers .mp3 downloads only and cannot save your conversions.

Paid plans start at $12 a month for Starter, which adds 1 hour of conversions, one custom voice model slot, commercial use and .wav downloads.

Pro costs $25 a month for 3 hours and 3 slots.

Ultimate is $49 a month with unlimited conversions and 8 slots.

Every paid tier includes a pitch editor, 14 instruments and mixed voices.

Enterprise customers get longer training datasets for custom models, help with voice training, a custom number of slots and API access.

If you plan to release what you make, you need a paid plan.
