Trying to design and build a very cheap "digital audio recorder". I've located some cheap a/d d/a's with serial memory interfaces from Microchip. I'd like some suggestions as to memory section. I've never used and not familiar with serial ported memory. I'll take care of signal interfacing but, wouldn't it be nice to have something that just "dropped" (or cooperated) into place.
The circuit will record audio until instructed to playback. Then it'll just playback the last n seconds forever.
Thank you.
