Yes !! This has got to be the best solution [which I never thought of]:
ISD has been doing this stuff for years.
Didn't they make the 'sounding' birthday-cards -- a mass consumer
item level product; compatible with pic volume/prices ?
Or telco answering machines.
Is it easy to save the digital audio captures to separate IDE files,
for later randomly selected re-down-load to the ISD chip for
play back ?
I.e hack the intended configuration, to be able to accumulate a lot of
telco voice recordings saved on IDE for later random access replay.
Or is the data from the CPU/dsp to the flash-mem not accessible ?
