Say you have a H264/DTS MKV video file and you want to extract the center channel, as WAV, for easy editing.
- Download tsMuxeR and extract the audio stream as a .dts (eg. "multichannel.dts"), using the GUI
- Download eac3to and run the following command to convert to a multichannel PCM WAV:
eac3to.exe multichannel.dts multichannel.wav
- Download wavosaur and open the multichannel WAV. Then kill the channels you don't need, edit the file, etc.
