Sound design from text.
A wooden door creaking open. Distant thunder on metal roofing. Footsteps on gravel, running. Describe the scene; the model generates broadcast-quality audio. ElevenLabs SFX is best-in-class; Stable Audio 2.5 handles longer ambient tracks up to 190 seconds.
Music with vocals and lyrics.
