Stereo WAV file recorder (Ruby)

[User108]

Hi all! I've made some changes to original mono wave recorder schematic found somewhere here. Now it supports mono /stereo recording not only streaming to disk, but also in memory (for slow hdd).
Also added an "Add" mode when recording appends to a previous one.
Could not make Add mode to work in disk record mode - that's why this mode works only in Disk Rec mode off.
Attached a simple delay to right channel to make stereo out of mono input. Hopefully will be of use to someone. I once stumbled upon somebody asking for this feature on StackOverflow, using the same Ruby wave class and mono wave recorder schematic..

I think I should add indication of memory usage when recording to RAM - by counting recording buffer array size. But not shure of exactness of this method, because arrays in Ruby also use some other information for self organization.
