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.

In many cases a DC offset is caused by the analogue parts of the system that add a DC current to the audio signal. Such analogue parts might be any analogue component that is part of the audio path like: the sound cards or the microphone.
DC Offset - Hack Audio

The term, “DC Offset,” is commonly used by audio engineers to describe this operation. From the days of analog circuits, there were two types of current: direct current (DC) and alternating current (AC). When direct current was applied to alternating current, the result was a signal shifted away from zero.

DC Offset DC offset occurs when hardware, such as a sound card, adds DC current to a recorded audio signal. This current results in a recorded waveform that is not centered around the baseline. In some cases, when DC-Offset is present, glitches and other unexpected results can occur when sound effects are applied to the audio file.
What is "DC Offset"? - Sweetwater

DC offset is an imbalance that sometimes occurs in A/D converters (see WFTD archive “ A/D Converter “). When working with audio it is desirable to have only the audio program material passed through the signal path. Almost by definition audio, being a periodic waveform, is an AC (Alternating Current) signal.
How to Fix DC Offset and Transformer Hum In Your …
https://www.pooraudiophile.com/2015/03/how-to-fix-dc-offset-and-transformer.html
DC Offset, sometimes called “DC in the AC,” is usually the result of unbalanced loads or flaws in the power distribution system. This can cause DC current flow in the transformers that power your audio equipment, making them run hotter and produce an audible, mechanical hum. In some extreme cases, DC offset can even damage your equipment.
What is the DC offset in audio? - Quora

This DC offset is removed by AC coupling built into your audio system. However, there will be a loud thump when you just connect the audio jack because of sudden transition in DC offset from max to 0 by this filter. This thump may have caused a mechanical damage in one of the loudspeakers. 2. Many times chassis ground of di Continue Reading
How to Measure DC Offset: 5 Steps (with Pictures) - …
https://www.wikihow.com/Measure-DC-Offset
DC offset (also known as DC bias) is a concept employed when dealing with electrical components, most notably audio equipment. These components send either power or audio signals using alternating current (AC), by which the signal reverses direction regularly.

Ideally, there will be no DC voltage (offset voltage) across the speaker terminals of an amplifier. Most amplifiers have a small amount of DC. Most people (those building or repairing amplifiers) consider 0.025v or less to be acceptable. 0.1v may be acceptable for others.
DC offset...what does this refer to? | Car Audio Forum ...
https://www.caraudio.com/threads/dc-offset-what-does-this-refer-to.44911/
Basically it refers to some DC voltage that an AC voltage "rides on". One example: In an electronic system that outputs AC voltage (like an amplifier), if the driver circuit is not perfectly balanced there can be a DC component (DC offset) on the output. Like if you put a voltmeter on the speaker, with no audio you'd measure some DC voltage.
