Hi

Thanks for the reply.

well there is a special  chip by ISD it is called ISD chipcorder
you probably know this already.
the Isd chipcorder can happly record any speech in analog format so
the problem of a/d and d/a conversion is gone.
what i need is a pic wizard to program a pic for me :-) so that it can
capture the clock data from external clock  module and map this
information to the recorded speech on the ISD chipcorder.

Do you think a pic can do this?

S+
