# Custom Node for ComfyUI
https://github.com/Saganaki22/ComfyUI-NovaSR
## 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.
| Model | Speed (Real-Time) | Model Size |
| :------------ | :---------------- | :--------- |
| **NovaSR** | **3600x realtime** | **~52 KB** |
| FlowHigh | 20x realtime | ~450 MB |
| FlashSR | 14x realtime | ~1000 MB |
| AudioSR | 0.6x realtime | ~6000 MB |
