[AudioI] single channel\single file\different recording using Sox

[Matt]

I have created a new application in gtkIOStream. It is a command line 
application which splits captured channels to individual audio files.

The code is here :

https://github.com/flatmax/gtkiostream/blob/master/applications/ALSACaptureSplitter.C

You can use it like so :

ALSACaptureSplitter -c 8 -r 48000 -t 5.1 /tmp/test wav

This command will split 8 channels to individual audio files in 
/tmp/test*.wav. It will record at a rate of 48 kHz and record for 5.1 
seconds. To see all options, run ALSACaptureSplitter -h

You will need to do a full compile of gtkiostream to get the application 
to work.

Do you know how to copmile gtkiostream ?

p.s. this doesn't do Octo channel swapping fixes ... I can add that 
later once you get this running.
