Hi.
Out of curiosity, I am just wondering how to sample data at 44.1kHz. I know the history behind CD with 44.1kHz sampling rate. But how they do it with a timer interrupt ?
I have been sampling data with interval timer at 25microseconds which equivalent to 40ksps. But I am confused on how to sample data at 44.1kHz. Should I just pass 22.6757 microseconds interval timer (which is not round number) ?? If the interrupt is at 20microsecs, it would become 50ksps instead. Hope Paul or other experts see this
Many thanks and have a great day !
