I would like to make a recording and playback system.(voice recorder) It should start recording by the sound-signal and record for 3 minutes beginning and ending with a bleep. Its also necessary to have a switch so you can listen back for at least half an hour.
I have been searching quite while how to make this but I get a bit lost in the information and don't know where to start or where to find a similar example. So what components do I need and does someone have some recommendations?

Mijn dank is groot.

This is because what you ask is impossible on the normal Arduinos. it only 2K of memory you have about enough memory to record about a quarter of a second.

However if you get the new Due this will allow you to record sound but 3 minutes is out of the question again due to lack of memory. Have you worked out how much you need for that?
