One of the few downsides to all our amazing digital hardware and software is that it’s nowhere near as forgiving as our older analog gear. And nothing’s worse than laying down a perfect track and then discovering there’s a tiny digital click at a crucial part of the song. You might be able to hide it in a dense mix, but in a sparse arrangement, it’s pretty much impossible. That’s why Peak includes a very simple way to find and repair those pesky clicks. Not surprisingly, the feature is called Repair Clicks and is found in the DSP menu. It allows you to find all clicks or pops in an audio document automatically.
Repair Clicks works by looking for any significant discontinuity from sample to sample. If it sees a value of -100 followed by a sample value of 10,000, it’s almost certainly a click. Once the artifact is located, a smoothing technique is used to eliminate the click and substitute interpolated data from the audio before and after the click. Peak also allows you to do the repair surgically by yourself using the pencil tool to draw in a smooth waveform.
