Make your audio sound clearer, fuller, and more professional — in one click.

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. 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.

• 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

• 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
