The linked tar-ball includes jcapture-0.0.1.cpp that
does not save any .wav file.
Oh my God! I confused jcapture-0.0.1.cpp (the first attempt) and jcapture-1.0.0.cpp. I
will upload the good one during this week-end.
I presume by "frequency shifting & frequency
sweeping" you mean resampling the signal & playing it back, not true "pitch
shift" with time remaining constant..?
Yes, that is, just resampling. Shifting the frequency by 2 means taking a sample of two,
and the playback time is divided by two.
Thanks for the feedback. I will look at comments and links.
