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.
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.
Usage instructions for onnx/pytorch and source code are available on GitHub:

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