This application uses state-of-the-art source separation models to remove vocals from audio files. UVR's core developers trained all of the models provided in this package (except for the Demucs v3 and v4 4-stem models).
These bundles contain the UVR interface, Python, PyTorch, and other dependencies needed to run the application effectively. No prerequisites are required.
If you do not have FFmpeg or Rubber Band installed and want to avoid going through the process of installing them the long way, follow the instructions below.
**FFmpeg Installation**
- Download the precompiled build [here](https://www.gyan.dev/ffmpeg/builds/ffmpeg-release-essentials.zip)
- From the archive, extract the following file to the UVR application directory:
<summary>MacOS Users: Having Trouble Opening UVR?</summary>
> Due to Apples strict application security, you may need to follow these steps to open UVR.
>
> First, run the following command via Terminal.app to allow applications to run from all sources (it's recommended that you re-enable this once UVR opens properly.)
>
> ```bash
> sudo spctl --master-disable
> ```
>
> Second, run the following command to bypass Notarization:
- Once everything is done installing, download the correct FFmpeg binary for your system [here](http://www.osxexperts.net) and place it into the main application directory.
- If FFmpeg is not installed, the application will throw an error if the user attempts to convert a non-WAV file.
- Memory allocation errors can usually be resolved by lowering the "Chunk Size".
