How to choose
- Price per minute of audioCheck the price per minute of generated audio and whether stems cost extra, because a track exported as stems can cost more than a single mix.
- Maximum track lengthCheck the longest track a single job returns and whether longer songs are built by extending, because an agent stitching sections must keep key and tempo consistent.
- Stems and vocal controlCheck whether stems and separate vocal tracks can be exported, since an agent producing a backing track for a human singer needs the instrumental without the voice.
- Output licence and training dataCheck the licence the output comes with and what training data the model used, because commercial reuse of a track depends on both.
