The APR6008, a chip I have managed to source to do some sound recording experiments. I am getting pretty annoyed at the manufacturer (without straying too much off the subject) they offer bugger all in terms human communication. In fact, I'm not sure they know what they are selling. Just another greedy company.
The spec sheet is elaborate enough, though there are some ambiguities that need ironing out.
do you know this chip by any chance?
