DC Offset
Audio that is not centered around the zero baseline in the waveform display is said to have a DC offset. DC offsets are typically caused by
electrical conflicts between the sound card and input device. The DC Offset function (located on the Process menu) is used to change
the baseline of an audio file by adding a constant value to each sample to compensate for offsets.
Estimating DC Offset
You can estimate the DC offset of an audio file by choosing Statistics from the Too ls menu.
