Design and Supply a schematic diagram of an 'Audio Delay' circuit.
The design should use components that are available at Digikey.
The cost of parts should not be more than $25USD.
The power supply voltage should not exceed 12volts DC, 5V supply is prefered.
The prefered delay of audio is 1 second.
The circuit should function.
The audio input is from an electric microphone.
The audio output should drive an 8ohm 5w speaker.
