Logic Pro X keyboard command of the day. #LogicProX @StudioIntern1
Remove DC Offset ⌃D
I don’t recall ever seeing an audio file with DC on it, but I know how to remove it. Removing DC offset will present a dialog box indicating how much offset is found, and requiring you to confirm removal. In my case all I ever see is 0.00%, so I cancel.
Some audio interface hardware can layer direct current (DC) over the audio signal. This results in a vertical shift of the waveform position that can be clearly seen in the Audio File Editor. It can also cause crackling sounds at the start and end of the audio region during playback. Choose Functions > Remove DC Offset to center the waveform around the zero amplitude line.
