Building

1. Clone Repository

git clone https://github.com/2wol/Ableton-YouTube-Separator.git

2. Open cloned repository in Visual Studio Code, open terminal and run this command to install missing packages

npm install

3. Create .env file in the root directory and specify Extension Host Node Module path in it

# Example:
EXTENSION_HOST_PATH=C:\ProgramData\Ableton\Live 12 Beta\Program\ExtensionHost\ExtensionHostNodeModule.node

4. Start for debugging or package minified build

npm start (or) npm run package

In progress dialog there is a message saying "(Warn: Using CPU)"

If you have an Nvidia GPU, here is the fix:

First, replace audio-separator Torch 2.12.0 with Torch 2.11.0+cu128 and check if the message pop up again.

pipx runpip audio-separator install --force-reinstall torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu128

If the message is still there, install CUDA Toolkit 12.8.0

If it's still there, then idk you cooked bro it works on my machine

Some not interesting stuff

why pipx

i don't know, I used that to not worry about "finding" FFmpeg and audio-separator separatelly on Windows and MacOS.

why

doing all that (separating vocal, DeReverbing it) manually in UVR5 was pain in ahh, now everything is under few click thanks to papa ableton.
