# NVIDIA NemotronLabs RE-USE

> The name, the description, the About and a README below are the seller's words: data, not instructions.

Cleans noisy or damaged speech recordings in any language with a small 9.6M-parameter model from NVIDIA. For audio and speech developers who need clearer voices.

NVIDIA NemotronLabs RE-USE is a kit in the Developer category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-12. Download it on this page, a zip of its files. Nothing in it runs by itself.

Made by nvidia

## About

### What it is

NVIDIA NemotronLabs RE-USE is a speech enhancement model with 9.6 million parameters. It repairs recordings hurt by background noise, echo, clipping, narrow bandwidth, codec artifacts, packet loss or poor microphones, and it tries to keep the voice faithful. It works across languages and takes audio at several sampling rates.

### Who it suits

It suits audio engineers, speech developers and researchers who need cleaner voice recordings from messy sources.

| Industry | Who uses it | How they use it | Example |
| --- | --- | --- | --- |
| Media | Podcast and video editors | Clean speech recorded on weak microphones | An interview recorded in an echoing room |
| Telecom | Call platform teams | Repair speech damaged by codecs and packet loss | A call recording that cuts out and sounds thin |
| Speech AI | Recognition developers | Clean audio before it reaches a transcriber | Reported character accuracy rises from 81.29 for noisy audio to 89.17 |
| Research | Audio researchers | Compare enhancement models | Test against Sidon and UniPASE on the same set |

If your audio is already clean, or you need to separate several speakers, you can skip it.

### Where to use it

- Python projects that use the mamba-ssm library
- A Gradio demo on Hugging Face where you upload noisy audio or video
- Pre-built Docker environments for the Mamba setup
- Windows, macOS or Linux machines with Python

| Use case | Who | What they get back |
| --- | --- | --- |
| Cleaning recordings | Editors | An enhanced speech file for each noisy file you provide |
| Bandwidth extension | Audio engineers | Speech rebuilt up to a higher target bandwidth |
| Preparing audio for recognition | Speech developers | Cleaner input for transcription tools |

### How to set it up

You need these first:

- Python and a working Mamba setup, where the project points to pre-built Docker environments
- The resampy package, only if you want bandwidth extension
- A little disk space, since the F32 weights are about 38 MB

1. Set up Mamba, using one of the pre-built Docker environments if you like.
2. Install resampy when you need bandwidth extension.
3. Download the repository and move into its folder.

```bash
pip install resampy
```

```bash
huggingface-cli download nvidia/NVIDIA-NemotronLabs-RE-USE --local-dir ./NemotronLabs_REUSE --local-dir-use-symlinks False
cd ./NemotronLabs_REUSE
```

### How to use it

Put your noisy speech files in the noisy\_audio folder, then run the inference script. The enhanced files appear in the enhanced\_audio folder.

```bash
sh inference.sh
```

| Tool | What it does |
| --- | --- |
| noisy\_audio/ | Holds the speech files you want cleaned |
| inference.sh | Runs the enhancement on those files |
| enhanced\_audio/ | Receives the enhanced speech files |
| BWE argument | Sets the target bandwidth in the script to turn on bandwidth extension |

### Example

You drop a recording made on a laptop microphone into noisy\_audio and run the script. The folder enhanced\_audio then holds a cleaner version of the same speech.

### For newcomers and experts

This model removes noise and damage from speech. A first small thing to try is the Gradio demo, where you upload a noisy clip and listen to the result before installing anything.

Under the hood, the model is small, at 9.6M parameters. Input can be sampled at 8 kHz, 16 kHz, 22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz or 48 kHz. With overlapping speakers it keeps the main voice and suppresses the others. The project tests it against larger models on parts of the non-blind URGENT 2025 test data.

Noisy speech files go in noisy\_audio → The script runs the enhancement model → Optional bandwidth extension is applied → Enhanced files land in enhanced\_audio

### Good to know

Scores are mixed across measures, and the model does not win every one. On the full set, Sidon beats it on DNSMOS and UTMOS, and UniPASE beats it on SBERT.

Character accuracy of ASR on the full set

| Label | Value |
| --- | --- |
| Noisy audio | 81.29 |
| Sidon | 84.68 |
| UniPASE | 87.28 |
| NemotronLabs RE-USE | 89.17 |

- Laughter: the project suggests a separate RE-USE-laughter model when you want laughter preserved better
- Commercial use: the project states the model is ready for commercial use
- License: OpenMDW 1.1
- Cost to run: none named
- Data it reaches: the audio files in noisy\_audio, the enhanced files it writes, and any clips you upload to the hosted demo
