DC offset is a mean amplitude displacement from zero. In Audacity it can be seen as an offset of the recorded waveform away from the center zero point. DC offset is a potential source of clicks, distortion and loss of audio volume. This page explains the causes and dangers of offset and how to remove it.

Why does DC offset occur?
In audio recording, a DC offset is an undesirable characteristic. It occurs in the capturing of sound, before it reaches the recorder, and is normally caused by defective or low-quality equipment. It results in an offset of the center of the recording waveform that can cause two main problems.
What is DC offset in power quality?
A fault at zero degrees on the A-Phase voltage means that there is zero voltage when the fault is applied to the system. When the voltage is zero in an inductive circuit, the current must be maximum. Therefore the maximum DC offset occurs when the voltage is zero.
What is DC offset in logic?
DC offset is a nasty little component of many digital audio signals that, while often inaudible, can add to the noise floor of your project. At worst, DC offset can result in an audible “click” on the beginning or end of an audio clip that has been edited. You can see DC offset by zooming in on a view of a waveform.
