Doesn't sound as good to me, maybe it's just a bad sample. I for some reason ( I know the math tells me otherwise ) I find it sounds better the faster I sample, like 500M. I feel like it has something to do with more exact following of the FM signal curve or something.
So how exactly does the software FM Demod work ( crossing detection )? And why can my $5 toy FM radio sound so much cleaner? On Mon, Mar 12, 2012 at 9:09 PM, Marcus D.
