We say that a signal has a DC offset distortion when the mean amplitude of its waveform is not zero. A normal voice is a symmetric sine signal, where the high peak equals to the low peak. In case there is a DC offset, the sine signal is not symmetric and the average over time is not zero.

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 …

If multiplying a number by a signal scales the amplitude, adding a number to a signal performs an offset. From a waveform plot, addition shifts the value of every sample up (or down) by the same amount. 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: …

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.

I need to measure the DC offset of an audio signal at various points in a circuit. The signal amplitude can vary between +-12V. Ideally, I would like to be able to measure offsets with a precision of a few micro volts. I was thinking of using an ADC like AD7794 to get the resolution and to to have a low
