|
## 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 4.0.0** here (link pending)
|
|
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.
|
|
- All output audio files will be the *'.wav'* format.
|
|
|
|
## Option Guide
|
|
|
|
### 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.
|
|
|
|
### 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_w512_nf2048.pth'**. The *'_sr44100_hl512_w512_nf2048'* portion automatically sets the *SR*, *HOP LENGNTH*, *WINDOW SIZE*, & *N_FFT* values within the application. If there are no values appended to the end of a selected model filename, the *SR*, *HOP LENGNTH*, *WINDOW SIZE*, & *N_FFT* fields will be editable and auto-populate with default values.
|
|
|
|
- **Default Values:**
|
|
- **SR** - 44100
|
|
- **HOP LENGTH** - 1024
|
|
- **WINDOW SIZE** - 512
|
|
- **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.
|
|
|
|
