Possible addition of Advanced Audio Channel Manipulation

[JavaShipped]

Hey there, I've been trying (and failing) to execute an ffmpeg command that will split my 5.1 video into 6 seperate audio tracks as detailed here.

This would be a powerful addition to the default GUI toolset!

As an Edit: I'm trying to train a tensor flow AI model for vocal isolation for film and TV - whereas most traditional models are for music. At the moment, my workflow is:

Split Audio into 5.1 -> Isolate the centre (vocal) channel -> Save centre channel -> Save other channels.

It's very tedious in Adobe Audition or Audacity considering I've got a data set of around 60 hours and I was hoping ffmpeg would be my saviour!
