About

This application is a GUI version of the vocal remover AI created and posted by GitHub user tsurumeso. This version also comes with eight high-performance models trained by us. You can find tsurumeso's original command-line version here.

Change Log

  • v4 vs. v5

    • The v5 models significantly outperform the v4 models.
    • The extraction's aggressiveness can be adjusted using the "Aggression Setting". The default value of 10 is optimal for most tracks.
    • All v2 and v4 models have been removed.
    • Ensemble Mode added - This allows the user to get the strongest result from each model.
    • Stacked models have been entirely removed.
      • Stacked model feature has been replaced by the new aggression setting and model ensembling.
    • The NFFT, HOP_SIZE, and SR values are now set internally.

  • Upcoming v5.2.0 Update

    • MDX-NET AI engine and model support

Installation

The application was made with Tkinter for cross-platform compatibility, so it should work with Windows, Mac, and Linux systems. However, this application has only been tested on Windows 10 & Linux Ubuntu.

FFmpeg

FFmpeg must be installed and configured for the application to process any track that isn't a .wav file. Instructions for installing FFmpeg can be found on YouTube, WikiHow, Reddit, GitHub, and many other sources around the web.

  • Note: If you are experiencing any errors when attempting to process any media files, not in the .wav format, please ensure FFmpeg is installed & configured correctly.

Running the Vocal Remover GUI & Models

  • Open the file labeled 'VocalRemover.py'.
    • It's recommended that you create a shortcut for the file labeled 'VocalRemover.py' to your desktop for easy access.
      • Note: If you are unable to open the 'VocalRemover.py' file, please go to the troubleshooting section below.
  • Note: All output audio files will be in the '.wav' format.

Option Guide

Main Checkboxes

  • GPU Conversion - Selecting this option ensures the GPU is used to process conversions.
    • Note: This option will not work if you don't have a Cuda compatible GPU.
    • Nvidia GPUs are most compatible with Cuda.
    • Note: CPU conversions are much slower than those processed through the GPU.
  • Post-process - This option can potentially identify leftover instrumental artifacts within the vocal outputs. This option may improve the separation of some songs.
    • Note: Having this option selected can adversely affect the conversion process, depending on the track. Because of this, it's only recommended as a last resort.
  • TTA - This option performs Test-Time-Augmentation to improve the separation quality.
    • Note: Having this selected will increase the time it takes to complete a conversion.
  • Output Image - Selecting this option will include the spectrograms in .jpg format for the instrumental & vocal audio outputs.

Special Checkboxes

  • Model Test Mode - Only selectable when using the "Single Model" conversion method. This option makes it easier for users to test the results of different models and model combinations by eliminating the hassle of manually changing the filenames and creating new folders when processing the same track through multiple models. This option structures the model testing process.
    • When ' Model Test Mode' is selected, the application will auto-generate a new folder in the ' Save to' path you have chosen.
    • The new auto-generated folder will be named after the model(s) selected.
    • The output audio files will be saved to the auto-generated directory.
    • The filenames for the instrumental & vocal outputs will have the selected model(s) name(s) appended.
  • Save All Outputs - Only selectable when using the "Ensemble Mode" conversion method. This option will save all of the individual conversion outputs from each model within the ensemble
    • When 'Save All Outputs' is un-selected, the application will auto-generate delete all of the individual conversions generated by the ensemble.

Additional Options

  • Window Size - The smaller your window size, the better your conversions will be. However, a smaller window means longer conversion times and heavier resource usage.

    • Here are the selectable window size values -
      • 1024 - Low conversion quality, shortest conversion time, low resource usage
      • 512 - Average conversion quality, average conversion time, normal resource usage
      • 320 - Better conversion quality, long conversion time, high resource usage

  • Aggression Setting - This option allows you to set how strong the vocal removal will be. The range is 0-100. The higher the value, the more the vocal data will be removed. Higher values can result in muddy-sounding instrumentals for instrumental models depending on the converted track, so this isn't always recommended. The default is 10 for instrumental & vocal models.

  • Default Values:

    • Window Size - 512
    • Aggression Setting - 10 (optimal setting for all conversions)

Other Buttons

  • Open Export Directory - This button will open your 'save to' directory. You will find it to the right of the 'Start Conversion' button.

Models Included

All of the models included in the release were trained on large datasets containing diverse sets of music genres. They were trained on different parameters, though they can convert tracks of all genres.

  • PLEASE NOTE: Do not change the name of the models provided! The required parameters are specified and appended to the end of the filenames.

  • Model Network Types

    • HP2 - The model layers are much larger. However, this makes them resource-heavy.
    • HP - The model layers are the standard size for UVR v5.

Here's a list of the models included within the package -

Main Models

  • HP2_3BAND_44100_MSB2.pth - This is a strong instrumental model trained using more data and new parameters.
  • HP2_4BAND_44100_1.pth - This is a strong instrumental model.
  • HP2_4BAND_44100_2.pth - This is a fine tuned version of the HP2_4BAND_44100_1.pth model.
  • HP_4BAND_44100_A.pth - This is a strong instrumental model.
  • HP_4BAND_44100_B.pth - This is a fine tuned version of the HP_4BAND_44100_A.pth model.
  • HP_KAROKEE_4BAND_44100_SN.pth - This is a model that removes main vocals while leaving background vocals intact.
  • HP_Vocal_4BAND_44100.pth - This model emphasizes vocal extraction. The vocal stem will be clean, but the instrumental might sound muddy.
  • HP_Vocal_AGG_4BAND_44100.pth - This model also emphasizes vocal extraction and is a bit more aggressive than the previous model.

Choose Conversion Method

Single Model

Run your tracks through a single model only. This is the default conversion method.

  • Choose Main Model - Here is where you choose the main model to perform a deep vocal removal.
    • The 'Model Test Mode' option makes it easier for the user to test different models on given tracks.

Ensemble Mode

Ensemble Mode will run your track(s) through multiple models and combine the resulting outputs for a more robust separation.

  • Choose Ensemble - Here, you choose the ensemble you wish to run your track through.
    • The 'Save All Output' option saves all of the outputs generated by each model in the ensemble.

Currently, there are 4 ensembles you can choose from. Below is a list of models included in each ensemble.

  • HP1 Models

    • HP_4BAND_44100_A
    • HP_4BAND_44100_B

  • HP2 Models

    • HP2_4BAND_44100_1
    • HP2_4BAND_44100_2
    • HP2_3BAND_44100_MSB2

  • All HP Models

    • HP_4BAND_44100_A
    • HP_4BAND_44100_B
    • HP2_4BAND_44100_1
    • HP2_4BAND_44100_2
    • HP2_3BAND_44100_MSB2

  • Vocal Models

    • HP_Vocal_4BAND_44100
    • HP_Vocal_AGG_4BAND_44100

  • PLEASE NOTE: Ensemble mode is very resource heavy!
