This circuit can be used to remotely monitor a loudspeaker, alarm, or audio source for presence of an audio waveform. It can also be directly connected across loudspeaker terminals used as a peak indicator.
A PC usually requires a plug-in ADC card to process analog signals. However, with this circuitry, a PC can communicate with an 18-bit ADC through its serial port.
