Priority Audio Switch - PAS
https://www.dcbnet.com/datasheet/pasds.html
For a typical installation using 4-wire E&M circuits, the Priority Audio Switch takes in two 4-wire E&M lines with the M-lead for switch control. The ports are paired as Priority and Secondary. The “Priority” will seize control of the audio channel …
Mixer circuit with input priority ? | All About Circuits

Priority encoder circuit with truth table for 8-bit and 4-bit are explained in the below section. 8 to 3 Priority Encoder. This kind of encoder is also named an 8-bit or Octal to Binary priority encoder. This type of encoder consists of 8 inputs and 3 outputs. When multiple inputs are active high at the same time, the input with the highest ...
Audio Switch Notes - Neat Circuits

The circuit below is an example of a simple audio switch: Values are not critical so experiment for best results. The 2N2222 or any signal NPN transistor is used to invert the control logic if required. Note there is no power required except to the 33k pullup resistor. This voltage can be from +5 to +15 volts.

3 HiFi Audio Circuit Design 3.1 DAC Circuit Design The DAC is the source of the analog audio signal chain, and the DAC is the performance bottleneck in the chain because the THD+N performance of the best DAC in the world is 10 + dB worse than the best amplifier. The DAC contains both analog and digital functional blocks and needs ultra-low ...

Audio Voice-Over - This is a circuit where a microphone and preamp circuit (voice circuit) have priority over any other audio signal. You can think of this as a one way intercom, if the main amplifier is used for listening to music, then when the push to talk switch is pressed, the amplifier is switched to the voice signal.
Audio Voice-Over Circuit
http://www.radanpro.com/Radan2400/Pojacala/Audio%20Voice-Over%20Circuit.htm
Voice-Over Circuit. In its simplest form, a voice-over unit is just a microphone and change-over switch feeding an amplifier, the output from the microphone having priority over the amplifiers audio signal when the "push-to-talk" switch is pressed. In this circuit, a preamplifier immediately follows the microphone and is designed to be used ...

https://github.com/sergeyfk05/AudioSwitcherSTM
Description. This project receives 4 or more audio channels to the input and outputs the first active audio channel in order of priority. If there is at least one active channel, then the logic unit is supplied to the LED and AMP outputs, thereby including a relay for the sound amplifier and an LED.
