AC Coupling - Sound on Sound
https://www.soundonsound.com/glossary/ac-coupling
AC Coupling (sometimes also known as DC-Blocking) is an electronic engineering arrangement that allows an audio (or any other alternating) signal to be passed through a connection while simultaneously preventing any DC bias or offset voltage on the source signal from getting through. In other words, AC coupling rejects any DC components within a signal, passing only …

When dealing with audio, we don’t want offsets for a number of reasons: it can limit dynamic range, it can damage audio equipment, and it can cause other issues when dealing with audio processing. Let’s look at what AC coupling would do to that initial offset sine wave:

Audio AC Coupling Help ! Using Arduino. General Electronics. DuaneB August 24, 2012, 4:30pm #1. Hi, I have an Arduino Audio project that has a 2.5V DC component that I want to dump before my amp - the audio signal from the Arduino is +5v to 0v centered on 2.5v. If i run the circuit into an commercial audio amp it works nicely, if however I run ...

Re: Audio AC coupling and DC bias. « Reply #1 on: June 17, 2010, 06:50:14 am ». If power supply pins of the MUX are connected to unipolar supply (+5V and 0 V for instance), then you definitely need the VCC/2 biasing on the signal. As a general rule, an input signal to the any IC should not exceed supply voltage (of course there are some ...

Audio detector with headphones; Length of telephone cable, several feet long (Radio Shack catalog # 278-872) ... This is precisely how oscilloscopes provide an “AC coupling” feature for measuring the AC content of a signal without any DC bias voltage: a capacitor is connected in series with one test probe.
