- 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.
