NovaSR: Pushing the Limits of Extreme Efficiency in Audio Super-Resolution

This is the model for NovaSR, a tiny 50kb audio upsampling model that upscales muffled 16khz audio into clear and crisp 48khz audio at speeds from 100-3500x realtime.

Audio Samples

Before Processing (16kHz): <audio controls> <source src="https://huggingface.co/drbaph/NovaSR/resolve/main/samples/speech_sample_before.mp3" type="audio/mpeg"> Your browser does not support the audio element. </audio>

After Processing (48kHz): <audio controls> <source src="https://huggingface.co/drbaph/NovaSR/resolve/main/samples/speech_sample_after.mp3" type="audio/mpeg"> Your browser does not support the audio element. </audio>

Details

• Model Size: 52kb for pytorch version
• Input Rate: 16kHz
• Output Rate: 48kHz
• Inference Speed: 300-3500x realtime depending on gpu
• Mono

Comparisons

Comparisons were done on A100 gpu. Higher realtime means faster processing speeds. Comparison on CPU are coming soon.
