Introducing Stable Audio 3.0 Integration
We're thrilled to announce that Stable Audio 3.0 - Stability AI's innovative music generation toolkit designed for creative exploration - is now available within ComfyUI. These models utilize legally sourced training data and deliver flexible audio duration, lightweight device-compatible versions, and enhanced structural coherence for longer compositions. Seamlessly transition between brief sound effects and extended musical pieces within your established workflows.
Key Features
Commercial licensing - Developed using fully authorized music datasets
Adaptable duration - Create content ranging from quick effects (~2 minutes with Small) to extended tracks (~6 minutes with Medium)
Efficient lightweight models - Operate Small SFX and Small music versions using standard processors without specialized graphics hardware
Enhanced musicality - Medium version produces richer compositions with stronger architecture when graphics acceleration is available
Model Variants
Small-SFX: Soundscapes and brief ambient segments (≤2:00)
Small-Music: Concise musical pieces and portable loops (≤2:00)
Medium: Extended compositions with improved structural integrity (~6:20)
The Small variant extends to two minutes (significantly longer than previous 11s/47s limitations), while Medium surpasses six minutes for extended sequences.
