Audio signals are always alternating current electrical signals. In terms of strength, microphone signals are the weakest form of audio signals, while …
Alternating Current Signals - AC Signals | IamTechnical.com
http://iamtechnical.com/alternating-current-signals-ac-signals
Audio and radio signals carried on electrical wires are also examples of alternating current. These types of alternating current carry information encoded (or modulated) onto the AC signal, such as sound (audio) or images (video). These currents typically alternate at higher frequencies than those used in power transmission.

Application of Alternating Current. AC is the form of current that are mostly used in different appliances. Some of the examples of alternating current include audio signal, radio signal, etc. An alternating current has a wide advantage over DC as AC is able to transmit power over large distances without great loss of energy.

Analog audio signals are alternating current (AC) electrical voltages, meaning they constantly reverse polarity from positive to negative. The rate of this oscillation determines the frequency of the signal, which can vary from less than 20 times a second (20Hz) to more than 22,000 (22kHz), the range of human hearing.

AC vs DC coupling: What is it? – Noise Engineering
https://noiseengineering.us/blogs/loquelic-literitas-the-blog/ac-vs-dc-coupling-what-is-it
The electrical signal flows out one module, through the patch cable, and into another module’s input. That signal might be alternating current (AC) or direct current (DC). AC signals will come from things like audio oscillators: oscillators make signals that move up and down, generally pretty fast.
DC-Offset - Sound on Sound
https://www.soundonsound.com/glossary/dc-offset
Audio signals are conveyed electrically as an 'alternating current' or 'AC' signal. This might typically result in a signal voltage that varies, for example, between +3 Volts and -3 Volts, with a waveform that is more or less symmetrical about the 0V line. However, there are circumstances — often, but not always, as the result of a fault condition — where instead of alternating equally above and …
What is Impedance in Audio? Input and Output …
https://virtuosocentral.com/what-is-impedance-in-audio/
When dealing with analog sound equipment, the audio signal that goes in or out of the system is a level of AC voltage and current. In audio devices, impedance is the measure of the resistance of a circuit to alternating current (audio signal). It’s measured in Ohms. The “Z” symbol represents impedance. All audio equipment that receives an input and has an output will have impedance …
