LavaSR(v2) is a novel 50MB BWE(bandwidth extension) model along with the UL-UNAS denoiser. It can enhance nearly 5000 seconds of audio in just 1 second while exceeding the quality of 6gb large diffusion models.

Details

Model Size: 50mb for pytorch version.
Input Rate: Any from 8-48khz.
Output Rate: 48kHz
Inference Speed: 20-80x realtime on CPU and 800-5000x realtime depending on GPU.

Use cases

Restore low quality audio datasets
Enhance TTS or ASR model quality.
Upscale poor quality voice calls.
