# Ultimate Vocal Remover GUI v5.0.0
|
||||
|
||||
## About
|
||||
|
||||
This application is a GUI version of the vocal remover AI created and posted by GitHub user [tsurumeso](https://github.com/tsurumeso). This version also comes with a total of 11 high performance models trained by me. You can find tsurumeso's original command line version [here](https://github.com/tsurumeso/vocal-remover).
|
||||
This application is a heavily modified version of the vocal remover AI created and posted by GitHub user [tsurumeso](https://github.com/tsurumeso). You can find tsurumeso's original command line version [here](https://github.com/tsurumeso/vocal-remover). The official v5 GUI is still under developement and will be released some time in Q3 2021. The v5 beta is available via command line only at this time. You can test it [here](https://github.com/Anjok07/ultimatevocalremovergui/tree/v5-beta-cml).
|
||||
|
||||
- **Special Thanks**
|
||||
- [tsurumeso](https://github.com/tsurumeso) - The engineer who authored the AI code. Thank you for the hard work and dedication you put into the AI application this GUI is built around!
|
||||
- [DilanBoskan](https://github.com/DilanBoskan) - The main GUI code contributor. Thank you for helping bring this GUI to life! Your hard work and continued support is greatly appreciated.
|
||||
|
||||
## 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.
|
||||
|
||||
### Install Required Applications & Packages
|
||||
|
||||
1. Download & install Python 3.7 [here](https://www.python.org/ftp/python/3.7.0/python-3.7.0-amd64.exe) (Windows link)
|
||||
- **Note:** Ensure the *"Add Python 3.7 to PATH"* box is checked
|
||||
2. Once Python has installed, download **Ultimate Vocal Remover GUI Version 4.0.1** [here](https://github.com/Anjok07/ultimatevocalremovergui/releases/download/v4.0.1/UVR_V4GUI_All_IN_ONE_12_10.zip)
|
||||
3. Place the UVR-V4GUI folder contained within the *.zip* file where ever you wish.
|
||||
- Your documents folder or home directory is recommended for easy access.
|
||||
4. From the UVR-V4GUI directory, open the Windows Command Prompt and run the following installs -
|
||||
|
||||
```
|
||||
pip install --no-cache-dir -r requirements.txt
|
||||
pip install torch==1.6.0+cu101 torchvision==0.7.0+cu101 -f https://download.pytorch.org/whl/torch_stable.html
|
||||
```
|
||||
|
||||
### FFmpeg
|
||||
|
||||
FFmpeg must be installed and configured in order for the application to be able 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 that are 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**](https://github.com/Anjok07/ultimatevocalremovergui/tree/beta#troubleshooting) section below.
|
||||
- **Note:** All output audio files will be in the *'.wav'* format.
|
||||
|
||||
## Option Guide
|
||||
|
||||
### Resolution Type:
|
||||
|
||||
- You can now choose the type of spectrogram the AI uses to analyze your track. Results will vary slightly between each option.
|
||||
|
||||
### Choose AI Engine:
|
||||
|
||||
- This option allows you to toggle between tsurumeso's v2 & v4 AI engines.
|
||||
- **Note:** Each engine comes with it's own set of models.
|
||||
- **Note:** The TTA option and the ability to set the N_FFT value is limited to the v4 engine only.
|
||||
|
||||
### Model Selections:
|
||||
|
||||
The v2 & v4 AI engines use different sets of models. When selected, the models available for v2 or v4 will automatically populate within the model selection dropdowns.
|
||||
|
||||
- **Choose Main Model** - Here is where you choose the main model to perform a deep vocal removal.
|
||||
- Each of the models provided were trained on different parameters, though they can convert tracks of all genres.
|
||||
- Each model differs in the way they process given tracks.
|
||||
- The [*'Model Test Mode'*](https://github.com/Anjok07/ultimatevocalremovergui/tree/beta#checkboxes) option makes it easier for the user to test different models on given tracks.
|
||||
- **Choose Stacked Model** - These models are meant to clean up vocal artifacts from instrumental outputs.
|
||||
- The stacked models provided are only meant to process instrumental outputs created by a main model.
|
||||
- Selecting the [*'Stack Passes'*](https://github.com/Anjok07/ultimatevocalremovergui/tree/beta#checkboxes) option will enable you to select a stacked model to run with a main model.
|
||||
- If you wish to only run a stacked model on a track, make sure the [*'Stack Conversion Only'*](https://github.com/Anjok07/ultimatevocalremovergui/tree/beta#checkboxes) option is checked.
|
||||
- The wide range of main model/stacked model combinations gives the user more flexibility in discovering what model blend works best for the track(s) they are proessing.
|
||||
- To reiterate, the [*'Model Test Mode'*](https://github.com/Anjok07/ultimatevocalremovergui/tree/beta#checkboxes) option streamlines the process of testing different main model/stacked model combinations on a given track. More information on this option can be found in the next section.
|
||||
|
||||
### 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.
|
||||
- Nividia GPU's are most compatible with Cuda.
|
||||
- **Note:** CPU conversions are much slower compared to 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 on *some* songs.
|
||||
- **Note:** Having this option selected can potentially have an adverse effect on 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.
|
||||
- **Note:** This option is ***not*** compatible with the *v2* AI engine.
|
||||
- **Output Image** - Selecting this option will include the spectrograms in *.jpg* format for the instrumental & vocal audio outputs.
|
||||
- **Stack Passes** - This option activates the stacked model conversion process and allows the user to set the number of times a track runs through a stacked model.
|
||||
- **Note:** Unless you have the *'Save All Stacked Outputs'* option selected, the following outputs will be saved -
|
||||
- Instrumental generated after the last stack pass
|
||||
- The vocal track generated by the main model
|
||||
- **Note:** The best range is 3-7 passes. 8 or more passes can result in degraded sound quality for the track.
|
||||
- **Stack Conversion Only** - Selecting this option allows the user to bypass the main model and run a track through a stacked model only.
|
||||
- **Save All Stacked Outputs** - Having this option selected will auto-generate a new folder named after the track being processed to your *'Save to'* path. The new folder will contain all of the outputs that were generated after each stack pass. The amount of audio outputs will depend on the number of stack passes chosen.
|
||||
- **Note:** Each output audio file will be appended with the number of passes it has had.
|
||||
- **Example:** If 5 stack passes are chosen, the application will provide you with all 5 pairs of audio outputs generated after each pass, if this option is enabled.
|
||||
- This option can be very useful in determining the optimal number of passes needed to clean a track.
|
||||
- The *'stacked vocal'* tracks will contain the audio of the vocal artifacts that were removed from the instrumental.
|
||||
- These files can be used to verify artifact removal.
|
||||
- **Model Test Mode** - This option makes it easier for users to test the results of different models, and model combinations, by eliminating the hassel of having to manually change the filenames and/or create 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 to them.
|
||||
- **Custom Parameters** - Checking this box allows you to set custom parameters (*SR*, *HOP LENGNTH*, & *N_FFT*) instead of the ones appended to the model filenames.
|
||||
- **Note:** Using the parameters the model was trained with is still recommended. This option is for testing.
|
||||
|
||||
|
||||
### Parameter Values
|
||||
|
||||
All models released here will have the values they were trained with appended to the end of their filenames like so, **'MGM-HIGHEND_sr44100_hl512_nf2048.pth'**. The *'_sr44100_hl512_nf2048'* portion automatically sets the *SR*, *HOP LENGNTH*, & *N_FFT* values within the application. If there are no values appended to the end of a selected model filename, the *SR*, *HOP LENGNTH*, & *N_FFT* fields will be editable and auto-populate with default values.
|
||||
|
||||
- **Note** - The WINDOW_SIZE value is universal. The smaller your window size, the better your conversions will be. However, a smaller window size means longer conversions times and heavier resource usage.
|
||||
- Here are the recommended 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
|
||||
- **272** - Best conversion quality, longest conversion time, heavy resource usage
|
||||
- *272 is the lowest window size value possible.*
|
||||
|
||||
- **Default Values:**
|
||||
- **SR** - 44100
|
||||
- **HOP LENGTH** - 1024
|
||||
- **WINDOW SIZE** - 320
|
||||
- **N_FFT** - 2048
|
||||
|
||||
### Other Buttons:
|
||||
|
||||
- **Add New Model** - This button will automatically open the models folder.
|
||||
- **Note:** If you are adding a new model, make sure to add it accordingly based on the AI engine it was trained on.
|
||||
- **Example:** If you wish to add a model trained on the v4 engine, add it to the correct folder located in the 'models/v4/' directory.
|
||||
- **Note:** The application will automatically detect any models added the correct directories without needing a restart.
|
||||
- **Restart Button** - If the application hangs for any reason, you can hit the circular arrow button immediately 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.
