Howdy, I'm using the audio daughter card on the 6713 DSK, which is sampling stereo 48 kHz. I believe this rate is fixed, via the jumpers on the board. I want to sample the data, but then decimate it to a lower rate, and send it back out to the daughter card. However, the output for the daughter card is still at the 48 kHz rate, not the lower decimated rate that I've just produced. My question is whether there is a way to get that 48 kHz output stream to sound like I was actually sending out at the lower decimated rate. Would just inserting 0's for the inbetween rates have this effect. For instance, if I were decimating by a factor of 4, from 48 kHz to 12 kHz ... could I just make every 4th sample on the way out from the 12 kHz stream, and have 0's in between ... to make the audio daughter card DAC actually sound like it was being run at a 12 kHz rate?
