Similarly, you will have the same issue when looping an audio clip as it has no zero-crossing.ĭC offset can also cause metering software/hardware to go haywire. Since the “zero” of an audio clip with DC offset has a value, it will create an audible “pop” when you split/splice it. The second issue you will face with DC offset is while editing. Notice how the height (peak level) is the same, but it’s clipping. The following pictures demonstrate the clipping problem: A typical waveform – note the height of the sine wave. You might also face issues in editing and metering. When a waveform is biased towards either the positive or the negative value, the higher value will reach the clipping level quicker. The worst problem with DC offset is that your audio will clip before it would as a normal audio waveform. And since DC offset essentially makes the waveform lean more towards one kind of signal over the other, we also call it DC bias. Now, if the waveform started alternating between +6v and –4v, you have a DC offset. Suppose you have a regular audio clip, and the waveforms are alternating between +5v and –5v. DC Offset is an imbalance between the positive and the negative signals in an audio waveform, where the zero becomes a different value, either positive or negative. ![]() ![]() ![]() In an audio clip, the horizontal line in the middle is zero, and the audio signal is recorded in positive (up) and negative (down) values. 4 Readings that you may like: What Is DC Offset?
