Quick Start
./audiogen.exe ./ "ambient forest sounds" 4 42
Arguments: <models_path> <prompt> <num_threads> <seed>
The runner will generate an output.wav file with 10 seconds of stereo audio at 44.1kHz.
Model Description
This is a converted version of the original stable-audio-open-small model by Stability AI, split into three optimized TensorFlow Lite models for mobile and edge deployment. Includes a ready-to-use C++ inference runner.
Architecture:
- Text Encoder: T5-based conditioner for prompt processing
- Diffusion Model: DiT (Diffusion Transformer) for latent generation
- Audio Decoder: Autoencoder for converting latents to audio
