LavaSR is a novel 50MB BWE(bandwidth extension) model along with the UL-UNAS denoiser.
Details
- Model Size: 50mb for pytorch version.
- Input Rate: Any from 8-48khz.
- Output Rate: 48kHz
- Inference Speed: 10-50x realtime on CPU and 400-4000x realtime depending on GPU.
Use cases
- Restore low quality audio datasets
- Enhance TTS or ASR model quality.
- Upscale poor quality voice calls.
Benchmark Comparison
| Model | Speed on GPU(bs=1) | Size | Input range | Quality |
|---|---|---|---|---|
| LavaSR | 4000x | 50MB | Any from 8-48khz | High |
| AudioSR | < 1x realtime | ~3gb+ | ~2-16khz | High |
| AP-BWE(previous formal fastest) | < 400x realtime | ~200MB+ | 8khz/12khz/16khz | Medium |
| NovaSR(previous informal fastest) | <3600x realtime | ~50KB+ | 16khz | Low |
