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 4-stem models).
Ultimate Vocal Remover
Ultimate Vocal Remover is a software tool designed to remove vocals from audio files using state-of-the-art source separation models. The application employs advanced deep neural networks to achieve precise vocal removal while preserving instrumental components. Key features include a user-friendly graphical interface and high-quality processing results. It is ideal for content creators, music producers, and remixers who need to isolate instrumental tracks for creative projects or personal enjoyment. Ultimate Vocal Remover can be installed via winget.

Ultimate Vocal Remover GUI v5.6
About
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.
Windows Installation
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.
Download the UVR installer for Windows via the link below:
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.
> 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:
>
> bash > sudo xattr -rd com.apple.quarantine /Applications/Ultimate\ Vocal\ Remover.app >
Step 3: Set Up a Virtual Environment (Recommended)
Setting 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
Install dependencies in the virtual environment:
pip install -r requirements.txt
Step 4: Run the Application
While the virtual environment is activated, start the application:
python UVR.py
Important Notes
Avoid Modifying System Files:
Previous instructions suggested deleting the /usr/lib/python3.11/EXTERNALLY-MANAGED file, 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.
If you encounter issues, refer to the GitHub Issues page for help.
Other Application Notes
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.
Performance:
Model load times are faster.
Importing/exporting audio files is faster.
Troubleshooting
Common Issues
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.
MacOS Sonoma Left-click Bug
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
Please be as detailed as possible when posting a new issue.
If possible, click the "Settings Button" to the left of the "Start Processing" button and click the "Error Log" button for detailed error information that can be provided to us.
