Fount Audio
Description
The for the audio block the fount we will be using a ISD1932 driver that will play two sounds on the fount. With two messages in the cup at the desired sampling rate by fixing the R_osc to 53.3 kΩ, each message can be about 10.65 seconds but we can loop these messages to be longer or decrease the sampling rate. Also V_CC = V_CCA = V_CCD ranging from 2.4V to 5.5v and V_SS = V_SSA = V_SSD are the ground voltage at zero volts.
