Hi Richard,

Thanks for the info.

Basically like other people have said it is more like 5 MIPS.. however my
code is "well structured" C, and in no way optimised yet. Actually for this
project I'll probably not bother to do any optimisation - This is probably
twice the rate I actually need :) If I get time I'll do it, but basically
I'm running out of that rapidly :)

I also have a bunch of other things going on in the PIC as well for this
application.

Actually, I've got an annoying glitch that you may be able to help with. I
seen to be unable to flush the buffer in the STA013, so that if I stop
playback, wait awhile and start a new song, I get a burst of sound that
seems to be what was left of the previous song. Any ideas on how to clear
the buffer? Has or Does this happen with your version?

Cheers,
Ash.
