DC Offset

Use this to remove DC Offset, which is usually an undesirable characteristic of a recording normally caused by defective equipment. This effect works like a high pass filter and has no controls. DC stands for Direct Current which is the average amplitude of the waveform. It sounds best when it is absent, represented by zero, so that there is no imbalance in the audio.
