MXA113 VOICE RECORDER 680 SEC 8 MASSAGES WITH 8W AMPLIFIER

This circuit can record (in digital format) and play back any voices which were then
stored in the IC (aPR33AX_C2). The playing back voices can be used in public relations
and advertising campaigns as well as the humanization of a donation box.
