The schematic for a very simple audio detector is shown below. Any audio level of -6 dBv or greater will maintain at least 0.5 volts DC at the output. This covers most "line level" audio sources. If greater audio sensitivity is needed, use germanium diodes (1N34) or Schottky diodes (1N5819) for D1 and D2. Audio Detection Schematic Setup

Detectors are intended to be used for balancing bridge measurement circuits, potentiometric (null-balance) voltmeter circuits, and detect extremely low-amplitude AC (“alternating current”) signals in the audio frequency range. It is a valuable piece of test equipment, especially for the low-budget experimenter without an oscilloscope.

Two similar circuits: A) Automatic input selector: If input A is connected to the output, if input B has audio signal the circuit switches to input B. B) Detect audio signal to switch relay on and after some time off again when the music has stopped.
