# Demucs Music Source Separation and Mixing

This Space uses the Demucs model to separate music into individual stems (vocals, drums, bass, and other) and allows you to mix them back together.

## Features

- Separate audio into four stems: vocals, drums, bass, and other instruments
- Choose from multiple Demucs models for separation
- Select which stems to include in the final mix
- Option to save the output as MP3 with adjustable bitrate
- Real-time progress updates with a sleek interface

## How to Use

1. Upload an audio file (WAV format recommended)
2. Select a Demucs model from the dropdown menu
3. Choose which stems you want in the final mix (vocals, drums, bass, other)
4. Optionally, select "Save as MP3" and adjust the bitrate
5. Click "Process" to start the separation and mixing
6. Wait for the process to complete (you'll see real-time updates)
7. Download the mixed audio and individual stems
