Audio Signal Switcher
June 16, 2020 - 2:33pm

Hey, I'm new here (and new to electronics in general).

I'm trying to use a 555 timer to build a circuit that redirects an audio signal into 1 or 2 paths.  (For now, let's say left/right speaker.)

I've already been able to build a circuit that alternates between 2 LED's.  Think of this circuit, but when one LED blinks, the audio signal goes left, and when the other blinks, the audio signal goes right.

My main thing is, I don't know how to incorporate the signal into this kind of circuit.

Any help would be appreciated.  Thanks.

Correction: I meant to say "1 of 2 paths", not "1 or 2 paths".

Use transistor

Use NPN and PNP transistor in the place of LEDs. It will work.

How exactly should the transistors be configured?

Audio signal flow is the path
July 20, 2020 - 11:29pm

Audio signal flow is the path an audio signal takes from source to output.The concept of audio signal flow is closely related to the concept of audio gain staging; each component in the signal flow can be thought of as a gain stage.

In typical home stereo systems, the signal flow is usually short and simple, with only a few components. However, in recording studios and performance venues, the signal flow can often be quite complicated, with a large number of components, each of which may cause the signal to fail to reach its desired output. Knowing each component in the signal flow becomes increasingly difficult and important as system size and complexity increases.
