It would be great to see this wrapped under (or both) perl and wxWidgets
    

Thanks for sharing that link Ed!  I have been struggling with finding an good cross platform audio library as well.  Indeed, it would be great to wrap this for perl.
  

Portaudio is the classic library and more mature, but at the time I found RtAudio cleaner and easier for smaller projects and also the Jack support was important to me.

RtAudio would also lend itself to implementation in a Wx style by hooking the non blocking API into wx events.  So basically you would instantiate a WxSound object, then set it to start playing at a certain sample rate with a certain number of channels and it would just fire a "feed me" event which lets you load it up with the next block of data and the same again to let you have any recorded samples. 

PortAudio and RtAudio are the only two really mature cross platform libraries that I am aware of though.
