Stable Audio is an advanced audio generation model designed to create high-quality audio tracks from textual prompts.
Key Features:
The model is intended for musicians, sound designers, and developers looking to create music, sound effects, or ambient sounds for various applications such as games, films, or interactive media.
Stable Audio primarily supports English for text prompts but can process multilingual inputs depending on the context of the prompt.
Stable Audio employs a latent diffusion model architecture optimized for audio generation. It uses a combination of a highly compressed autoencoder for efficient representation of audio waveforms and a diffusion transformer (DiT) that excels in manipulating data over long sequences.
The model was trained on a diverse dataset sourced from the AudioSparx music library, which includes over 800,000 audio files encompassing music, sound effects, and single-instrument stems.
Stable Audio has demonstrated impressive performance metrics:
| Metric | Score |
|---|---|
| Quality Index | High |
| Length of Generated Tracks | up to 47s |
| Sampling Rate | 44.1 kHz |
The model is available on the AI/ML API platform as "Stable Audio" .
