| | # 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 |
| | * **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. |
