Hello, I've used this my AudioSplitter.bat script placed in windows "send to" folder for quick access. It could probably be much smarter but anyways it does the job for me. It loops now 50 times and creates 24bit wav files.

The video could have N stereo streams (normally up to 16), M mono streams (up to 16), or a combination of both. Now I have to write the -map structure manually after probing the input. Ideally I need to end up with as many mono wavs as individual channels. If you could give me a starting point, I could probably figure out.
