README

FlashSR

FlashSR is a 2MB audio super-resolution model based on the HierSpeech++'s upsampler architecture. It upscales 16kHz audio to 48kHz at speeds ranging from 200x to 400x real-time.

Details

  • Model Size: 2MB for pytorch version, 500KB for onnx version
  • Input Rate: 16kHz
  • Output Rate: 48kHz
  • Inference Speed: 200x - 400x real-time depending on gpu and dtype

Performance Summary

FlashSR is designed for high-speed frequency reconstruction. It offers a significantly lower computational footprint compared to alternatives such as Resemble-Enhance and ClearerVoice, while maintaining similar output quality.

Benchmark Comparison

Model Speed Size
FlashSR 200x - 400x realtime 2MB/500KB
Resemble-Enhance < 20x realtime ~700MB+
ClearerVoice < 20x realtime ~200MB+

Credits

Thanks to the authors of HierSpeech++ as this was based on it's 48khz upsampler and Xenova for onnx code.
