FileNotFoundError: [WinError 2] The system cannot find the file specified

If you have this error then fear not, it can be fixed pretty easily:

• Download a binary executable from https://ffmpeg.org/download.html
• Add the executable to your project
• Add these lines of code in your script (before any calls to the rvc libraries):

  
  import os
  import pydub

pydub.AudioSegment.converter = os.getcwd() + "\ffmpeg.exe" # or any other path to ffmpeg, as long as it is absolute and not relative.

- You're good to go.
