Frequently Asked Questions
AudioLDM 2 generates original instrumental music (and on some engines, vocals) from a text prompt. Describe the mood, genre, instrumentation, or BPM and AudioLDM 2 returns a finished audio track.
10 to 60 seconds per generation depending on the engine. For longer pieces, chain multiple generations through /music/stitch/ or generate in 30-second segments and crossfade.
Some engines synthesize vocals from lyrics you provide (paste lyrics in the form); others are instrumental-only. Check the form on this page - a Lyrics field means vocals are supported.
Pop, rock, EDM, jazz, ambient, classical, lo-fi, hip-hop instrumentals all render reasonably. Niche genres (gamelan, Carnatic, throat singing) are weaker - describe instruments explicitly for best results.

Yes - /batch/ accepts a list of prompts. Each track lands in /account/?tab=history with the prompt as the filename. For more control, use the API.
Yes - POST your prompt to /v1/music/generate/ with model="AudioLDM 2". /api/ has the full reference including lyrics, duration, and tempo parameters.
