I am looking for a cheap method to record and playback about 15 seconds of
sound on a chip.

The whole setup, I GUESS, will comprise:
1) A microphone
2) An A/D converter that digitizes the sound
3) A unit that accepts the commands "record" and "playback"
4) Some memory that holds the sound image
5) A D/A converter to generate an analog signal
6) A speaker for playback
7) Power supply

Does a chip that has most/all the features except the power supply exist?

If there is an alternative/better method I would be extremely interested to
know.
