## What It Does

Got audio that sounds thin, muffled, or low-quality? This app uses an AI model called **LavaSR** to restore missing detail and bring your audio back to life — then saves it as a clean **48 kHz WAV** file, ready for professional use.

It's designed to be fast and simple. Drop your files in, click **Enhance**, and you're done.

> **LavaSR** is an independent open-source project developed by [ysharma3501](https://github.com/ysharma3501/LavaSR). This GUI is a separate application that uses it as a backend — all credit for the model and core enhancement technology goes to the LavaSR authors.

LavaSR runs at ~5000× realtime on GPU and ~60× on CPU, fits in ~500 MB VRAM with a ~50 MB model, and outperforms larger diffusion-based models on audio quality benchmarks.

## Perfect For

- Voice recordings that sound narrow or dull
- Old interviews, podcasts, or phone call recordings
- Audio samples you want to polish before a mix
- Batch-cleaning a folder of files before editing

---

## Features

- **One-click enhancement** — drop files, press Enhance, done
- **Batch processing** — handle multiple files at once, even from different folders
- **Optional denoising** — reduce background noise on top of enhancing
- **Drag output directly into your DAW or folder** — no hunting through directories
- **Flexible output options** — control the output folder, file suffix, and naming
- **Runs offline** — no internet needed after the model downloads once
