I am way behind you guys on the DSP-SDR subject but I appreciate every

I am currently trying to puzzle out the strategy used in acquiring
data from a sound card.

Using C++, it's not that hard. This page of my website,
http://sdeyoreo.tripod.com/id5.html gives the steps and code to
capture sound and fill an array with the samples from the soundcard.
Fell free to ask me more if you want.

I have successfully built the Softrock Lite 40 meter receiver and am
ever so slowly working on a Softrock RXTX Ver 6.2 40 M transceiver.
