Audio Signal Detector/Switch Circuit designed by David A. Johnson, P.E. For some audio systems it is desirable to have an automatic switch circuit turn on other devices, such as an Amplifier, if an audio signal is detected on one line. The hobby circuit below will activate a
Dual Input Audio Switching Circuit : 6 Steps (with ...
https://www.instructables.com/Dual-Input-Audio-Switching-Circuit/
This Instructable is about making a very simple 3.5mm stereo audio switching circuit. All you need is a switch, a few audio sockets, an enclosure of some sort and some wires. In this Instructable, I've made a switching circuit for 2 inputs and one output, but this can easily be expanded to several inputs and one output by swapping out the switch and using more audio …

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.
