Hi Tim,

Thanks, that's very informative feedback! How does oversampling work, 
practically speaking, in audio - I understand the concept from my years 
of computer graphics, but it is a little different when you don't 
necessarily control the fidelity of the input.

Would the approach to use a sample-rate converter to essentially 
interpolate samples, then do the processing, and then sample back down?

How does that work for live streams of data?
