Addressing Historical Limitations

Audio diffusion models have historically grappled with generating audio of fixed durations, often resulting in abrupt and incomplete musical phrases. The limitation arose due to training models on random audio chunks cropped from longer files, constrained to specific lengths. Consequently, the system encountered constraints in capturing the complete audio context. However, Stable Audio addresses this by enabling audio generation with lengths up to the training window size.

Key Features of Stable Audio

Stable Audio uses highly compressed audio data, boosting speed over raw audio. Additionally, it utilizes the NVIDIA A100 GPU for rapid 95-second stereo audio generation.”

The Core Architecture

Stable Audio integrates VAE, text encoder, and U-Net-based diffusion model for high-fidelity, noise-resistant audio generation. Utilizing Descript Audio Codec’s architecture, it efficiently compresses stereo audio into a lossy latent encoding, enhancing both generation and training speed.

Harnessing the Power of Text

To further enhance controllability and precision, Stability AI integrates text prompts into the audio generation process. A CLAP model-derived text encoder enriches text with audio relationships using specific properties. Embeddings per second, derived from audio properties, concatenate with text tokens for desired audio length.

Dataset and Training

Stability AI curated in collaboration with AudioSparx, Furthermore, Stability AI meticulously curated a vast dataset comprising 800,000 diverse audio files. This extensive collection, equivalent to 19,500 hours, served as the foundational training data for the remarkable Stable Audio model.

Future Endeavors and Advancements in Stability AI
