'[PICLIST] [PIC] Sampling'

Can anyone please recommend a particular PIC model for sampling and
processing analog data at 24bit 96khz (music related)
Thanx in advance.

There is no PIC with an on board 24 bit A/D converter.  You'll need to find an
external converter that will do the job for you (try TI).  In that case, you'll
need a PIC with lots of pins (I haven't seen any 16 bit or greater A/D
converters that operate in serial mode, only parallel), so nearly any PIC with
28 or 40 pins will read from one of those converters.

you would be best to look for the A/D converters designed to be used for CD's. The D/A side are readily available, but I am not sure of the A/D side. Check companies like Analog Devices and Burr Brown.

I think the choice of ADC is going to be the least of his worries.  At
96KHz, the average mid-range 20MHz pic will have around 50 instruction
cycles between samples from which has to be subtracted the overhead of
actually aquiring the samples..  If the "processing" is going to involve
multiplication or division, then things are going to get a little tricky,
especially with 24 bit math.

An 18C series PIC running at 40MHz with a hardware multiply might be able to
do something usefull, but really this is exactly thet sort of things DSP's
were designed for.  Simple 8 bit micro's like the PIC just don't have that
kind of horsepower.
