4/05/2020 verison 2.4 : This is a new installer if you are upgrading you must uninstall the previous version.
If you would like to compile your own version of the bundle, head over to my github page https://github.com/boy1dr/SpleeterGui and clone the project.
I use Visual C#2017 to compile it.
You will also need Python 3.7 and ffmpeg installed (make sure they are both in your environment variable PATH)
To install Spleeter, type the following...
python -m pip install spleeter
The GUI will look for python.exe in %appdata%\Roaming\SpleeterGUI\python
It will also need the [2stems.json, 3stems.json, 5stems.json] files from my original project which can be found here https://drive.google.com/open?id=1O6q68IPwPtAgdpK5ZSKiY5-Ew-jmUv9Y
Big thanks go to Grant and Brady for making contributions to this GUI project, we wouldn't have a fancy desktop app without you :)
