Voice-rec-3

Voicerec3 Manual:

This module uses a ISD1820PY voice recorder chip to playback sounds. 
This is the second module I have designed with this chip, the voicerec2 also uses this chip. The chip has a problem, the problem is that it powers off after it has played the sound it recorded, resulting in a nasty click in the sound. Tom Verbruggen told me a nice trick he uses to get rid of this click is to use a vactrol to make the volume go down when the rest LED turns on from the ISD1820, this seems to work so I implemented it in this module. The LED also starts the sample playback, so then it is permanently looped.

ON/OFF/ON TOGGLE SWITCH: 
The module has a gate input that can be set to shortened or normal gate or off using this switch.

The mic is located under the holes left of the black button.
