Command-line Tutorial

1. Create YAML:

   • corrscope split*.wav --audio master.wav -w
   • Specify all channels on the command line.
   • -a or --audio specifies master audio track.
   • Creates file master.yaml.

2. Edit master.yaml to change settings.

3. Play (requires ffmpeg):

   • corrscope master.yaml -p/--play

4. Render and encode MP4 video (requires ffmpeg)

   • corrscope master.yaml -r/--render
