ADAU1701 has algorithms of decompression for the reproduction of vocal messages saved in RAM.
If the answer is affirmative which is the procedure of decompression and reproduction.
SigmaDSP can't do the frequency-domain processing that's at the heart of compression algorithms like MP3. Thus, there isn't anything in the toolbox for coding or decoding audio.
I have to obligatorily use a chip of the nuvoton patience.
I had read here on the forum regarding this problem, a post of a person that had found a solution.
I don't succeed in finding this post anymore.
You that you follow by chance a lot the forum you remember yourself something?
Sorry I have not seen any such post, nor could I find any by search. Of all the SigmaDSPs, the ADAU1452 would be the most likely to accomplish perceptual audio coding (since it does block processing). As gas as I know, this has not yet happened.
