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-disable

Second, run the following command to bypass Notarization:

sudo xattr -rd com.apple.quarantine /Applications/Ultimate\ Vocal\ Remover.app

Manual MacOS Installation

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.

Linux Installation

See Linux Installation Instructions

These install instructions are for Ubuntu 22.10.

• Download and save this repository here
• From the saved directory run the following commands in this order-

sudo apt update && sudo apt upgrade
sudo apt-get update
sudo apt install ffmpeg
sudo apt install python3-pip
sudo apt-get -y install python3-tk
pip3 install -r requirements.txt

Other Application Notes

• Nvidia RTX 1060 6GB is the minimum requirement for GPU conversions.
• Nvidia GPUs with at least 8GBs of V-RAM are recommended.
• AMD Radeon GPUs are not supported at this time.
• 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.

Change Log

Most Recent Changes:

• Fixed Download Center model list issue.
• Fixed audio clip in ensemble mode.
• Fixed output model name issue in ensemble mode.
• Added "Batch Mode" for MDX-Net to increase performance.
  • Batch Mode is more memory efficient.
  • Batch Mode produces the best output, regardless of batch size.
• Added Batch Mode for VR Architecture.
• Added Mixer Mode for Demucs.
  • This option may improve separation for some 4-stem models.

Fixes & Changes going from UVR v5.4 to v5.5:

• The progress bar is now fully synced up with every process in the application.
• Drag-n-drop feature should now work every time.
• Users can now drop large batches of files and directories as inputs. When directories are dropped, the application will search for any file with an audio extension and add it to the list of inputs.
• Fixed low-resolution icon.
• Added the ability to download models manually if the application can't connect to the internet.
• Various bug fixes for the Download Center.
• Various design changes.

Performance:

• Model load times are faster.
• Importing/exporting audio files is faster.

New Options:

• "Select Saved Settings" option - Allows the user to save the current settings of the whole application. You can also load saved settings or reset them to the default.
• "Right-click" menu - Allows for quick access to important options.
• "Help Hints" option - When enabled, users can hover over options to see pop-up text that describes that option. The right-clicking option also allows copying the "Help Hint" text.
• Secondary Model Mode - This option is an expanded version of the "Demucs Model" option only available to MDX-Net. Except now, this option is available in all three AI Networks and for any stem. Any model can now be Secondary, and the user can choose the amount of influence it has on the final result.
• Robust caching for ensemble mode, allowing for much faster processing times.
• Clicking the "Input" field will pop up a new window that allows the user to go through all of the selected audio inputs. Within this menu, users can:
  • Remove inputs.
  • Verify inputs.
  • Create samples of selected inputs.
• "Sample Mode" option - Allows the user to process only part of a track to sample settings or a model without running a complete conversion.
  • The number in the parentheses is the current number of seconds the generated sample will be.
  • You can choose the number of seconds to extract from the track in the "Additional Settings" menu.

VR Architecture:

• Ability to toggle "High-End Processing."
• Support for the latest VR architecture
  • Crop Size and Batch Size are specifically for models using the latest architecture only.

MDX-NET:

• "Denoise Output" option results in cleaner results, but the processing time will be longer. This option has replaced Noise Reduction.
• "Spectral Inversion" option uses spectral inversion techniques for a cleaner secondary stem result. This option may slow down the audio export process.
• Secondary stem now has the same frequency cut-off as the main stem.

Demucs:

• Demucs v4 models are now supported, including the 6-stem model.
• Combining remaining stems instead of inverting selected stem with the mixture only when a user does not select "All Stems."
• A "Pre-process" model that allows the user to run an inference through a robust vocal or instrumental model and separate the remaining stems from its generated instrumental mix. This option can significantly reduce vocal bleed in other Demucs-generated non-vocal stems.
  • The Pre-process model is intended for Demucs separations for all stems except vocals and instrumentals.

Ensemble Mode:

• Ensemble Mode has been extended to include the following:
  • "Averaging" is a new algorithm that averages the final results.
  • Unlimited models in the ensemble.
  • Ability to save different ensembles.
  • Ability to ensemble outputs for all individual stem types.
  • Ability to choose unique ensemble algorithms.
  • Ability to ensemble all 4 Demucs stems at once.

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 "Chunk Size".

Issue Reporting

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.
