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.
-
Please Note:
- This installer is intended for those running Windows 10 or higher.
- Application functionality for systems running Windows 7 or lower is not guaranteed.
- Application functionality for Intel Pentium & Celeron CPUs systems is not guaranteed.
- You must install UVR to the main C:\ drive. Installing UVR to a secondary drive will cause instability.

Update Package instructions for those who have UVR already installed:
- If you already have UVR installed you can install this package over it or download it straight from the application or click here for the patch.
Windows Manual Installation
- Download and extract the repository here
- Download and install Python here
- Make sure to check "Add python.exe to PATH" during the install
- Run the following commands from the extracted repo directory:
python.exe -m pip install -r requirements.txt
If you have a compatible Nvidia GPU, run the following command:
python.exe -m pip install --upgrade torch --extra-index-url https://download.pytorch.org/whl/cu117
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
- From the archive, extract the following file to the UVR application directory:
ffmpeg-5.1.2-essentials_build/bin/ffmpeg.exe
Rubber Band Installation
In order to use the Time Stretch or Change Pitch tool, you'll need Rubber Band.
- Download the precompiled build here
- From the archive, extract the following files to the UVR application directory:
rubberband-3.1.2-gpl-executable-windows/rubberband.exerubberband-3.1.2-gpl-executable-windows/sndfile.dll
-
Please Note:
- The MacOS Sonoma mouse clicking issue has been fixed.
- MPS (GPU) acceleration for Mac M1 has been expanded to work with Demucs v4 and all MDX-Net models.
- This bundle is intended for those running macOS Big Sur and above.
- Application functionality for systems running macOS Catalina or lower is not guaranteed.
- Application functionality for older or budget Mac systems is not guaranteed.
- Once everything is installed, the application may take up to 5-10 minutes to start for the first time (depending on your Macbook).

MacOS Users: Having Trouble Opening UVR?
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.)
sudo spctl --master-disableSecond, run the following command to bypass Notarization:
sudo xattr -rd com.apple.quarantine /Applications/Ultimate\ Vocal\ Remover.app
Manual MacOS Installation
- Download and save this repository here
- Download and install Python 3.10 here
- From the saved directory run the following -
pip3 install -r requirements.txt
- If your Mac is running with an M1, please run the following command next. If not, skip this step. -
cp /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/_soundfile_data/libsndfile_arm64.dylib /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/_soundfile_data/libsndfile.dylib
FFmpeg Installation
- Once everything is done installing, download the correct FFmpeg binary for your system here and place it into the main application directory.
Rubber Band Installation
In order to use the Time Stretch or Change Pitch tool, you'll need Rubber Band.
- Download the precompiled build here
- From the archive, extract the following files to the UVR/lib_v5 application directory:
rubberband-3.1.2-gpl-executable-macos/rubberband
This process has been tested on a MacBook Pro 2021 (using M1) and a MacBook Air 2017 and is confirmed to be working on both.
See Linux Installation Instructions
These installation instructions are for Debian & Arch-based Linux systems.
- Download and save this repository from GitHub.
- Extract the downloaded file to a directory of your choice.
Use the following commands based on your system type:
For Debian-based systems (Ubuntu, Mint, etc.):
sudo apt update && sudo apt upgrade
sudo apt-get install -y ffmpeg python3-pip python3-tkFor Arch-based systems (EndeavourOS):
sudo pacman -Syu
sudo pacman -S ffmpeg python-pip tkSetting up a virtual environment (venv) ensures that the program's dependencies do not interfere with system-wide Python packages.
-
Navigate to the extracted repository directory:
cd /path/to/ultimatevocalremovergui -
Create a virtual environment:
python3 -m venv venv
-
Activate the virtual environment:
- For Debian-based and Arch-based systems:
source venv/bin/activate
- For Debian-based and Arch-based systems:
-
Install dependencies in the virtual environment:
pip install -r requirements.txt
While the virtual environment is activated, start the application:
python UVR.py-
Avoid Modifying System Files:
Previous instructions suggested deleting the/usr/lib/python3.11/EXTERNALLY-MANAGEDfile, which is dangerous and can break Python package management. Do NOT delete this file. -
Why Use Virtual Environments?
Virtual environments isolate the program's dependencies, preventing conflicts with system Python packages. More information is available here. -
Known Issues and Discussions:
If you encounter issues, refer to the GitHub Issues page for help.
- Nvidia GTX 1060 6GB is the minimum requirement for GPU conversions.
- Nvidia GPUs with at least 8GBs of V-RAM are recommended.
- AMD Radeon GPU supported is limited at this time.
- There is currently a working branch for AMD GPU users here
- This application is only compatible with 64-bit platforms.
- This application relies on the Rubber Band library for the Time-Stretch and Pitch-Shift options.
- This application relies on FFmpeg to process non-wav audio files.
- The application will automatically remember your settings when closed.
- Conversion times will significantly depend on your hardware.
- These models are computationally intensive.
- Model load times are faster.
- Importing/exporting audio files is faster.
- 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 "Segment" or "Window" sizes.
There's a known issue on MacOS Sonoma where left-clicks aren't registering correctly within the app. This was impacting all applications built with Tkinter on Sonoma and has since been resolved. Please download the latest version via the following link if you are still experiencing issues - link
