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 ### 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. - **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. **PLEASE NOTE:** Do not change the name of the models provided! The required parameters are specified and appended to the end of the filenames. Here's a list of the models included within the package - - **v4 AI Engine** - **Main Models** - **MGM_MAIN_v4_sr44100_hl512_nf2048.pth** - This is the main model that does an excellent job removing vocals from most tracks. - **MGM_LOWEND_A_v4_sr32000_hl512_nf2048.pth** - This model focuses a bit more on removing vocals from lower frequencies. - **MGM_LOWEND_B_v4_sr33075_hl384_nf2048.pth** - This is also a model that focuses on lower end frequencies, but trained with different parameters. - **MGM_LOWEND_C_v4_sr16000_hl512_nf2048.pth** - This is also a model that focuses on lower end frequencies, but trained on a very low sample rate. - **MGM_HIGHEND_v4_sr44100_hl1024_nf2048.pth** - This model slightly focuses a bit more on higher end frequencies. - **MODEL_BVKARAOKE_by_aufr33_v4_sr33075_hl384_nf1536.pth** - This is a beta model that removes main vocals while leaving background vocals intact. - **Stacked Models** - **StackedMGM_MM_v4_sr44100_hl512_nf2048.pth** - This is a strong vocal artifact removal model. This model was made to run with *'MGM_MAIN_v4_sr44100_hl512_nf2048.pth'*. However, any combination may yield a desired result. - **StackedMGM_MLA_v4_sr32000_hl512_nf2048.pth** - This is a strong vocal artifact removal model.
