Hi all, first post. I need help designing a voice storage system. I want to store about 5 short messages (less than a minute in most cases), and be able to play them back. I am trying to find a decent IC that can do this, but am not having any luck finding something readily available. The goal is to be able to listen to a voice-band radio and store the 5 most recent for playback. I'm thinking the "click" of the microphone keying up would make a fine "start and stop recording" trigger. It would also need to be able to throw the oldest message out to free up space for newer transmissions. This is likely least complicated with a dedicated microcontroller that can be programmed by PC or something, rather than discreet components. Attached is the concept block diagram. Any help at all would be appreciated.
