## NovaSR: Pushing the Limits of Extreme Efficiency in Audio Super-Resolution
|
| 11 |
+
|
| 12 |
+
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.
|
| 13 |
+
|

+
### Details
|
| 16 |
+
* **Model Size:** 52kb for pytorch version
|
| 17 |
+
* **Input Rate:** 16kHz
|
| 18 |
+
* **Output Rate:** 48kHz
|
| 19 |
+
* **Inference Speed:** 300-3500x realtime depending on gpu
|
| 20 |
+
* **Mono**

## Comparisons
|
| 23 |
+
Comparisons were done on A100 gpu. Higher realtime means faster processing speeds.
|
| 24 |
+
Comparison on CPU are coming soon.
