In the last few days we have had a few questions related to DSP.
How to compare two audio files?
and
Which freeware analysis software most closely resembles the functionality of Matlab DSP toolbox
The first question I linked to has been suggested to be better in stack overflow by endolith. While the second question was defended to stay on our site by both Joby Taffey and reemrevnivek here: Does this question seem to fit?
I have looked at the Stack Overflow tag for DSP and was actually rather unhappy. There are 157 questions tagged with the DSP tag, but most of them have gotten very little attention, especially for how active Stack Overflow is. I think this may be a case that the Stack Overflow experts are mostly Computer Science guys where as the experts on our site tend to be more in the Electrical Engineering field. In my experience EEs are much better suited to answer a DSP question then Computer Science guys.
So, where do you think we should draw the line here? DSP does tend to be much more programming oriented, which is what Stack Overflow is intended for however, our community seems to be better suited to answer the questions.
