As tedious as editing is, it is one of the most important process that contribute greatly to the sound quality of the final production.
It’s bad enough that you have to do the tedious task of audio editing. But it is even frustrating when your edits make the audio track worse. Every spit creates a terrible click or pop in your audio track.
Isn’t the point of editing to get rid of clicks and pop?
I wish someone had told me about this editing method I’m going to show you, when I first started out. Below I tell you why you keep on getting that click and the very simple method to prevent it.
You won’t believe how simple it is!
There is always that occasion when editing where you going to have to split the audio track in the middle of a word or a note. You listen to make sure you didn’t shorten the word or the note, but when you split the audio file, all you hear is that annoying pop at the beginning and end of the regions.
Cross-fade sometimes get rid of the pop, but not always.
So, why the pops?
This may be because of two reasons. To make things easy, lets say we are editing a sine wave. We want to cut the best part of the sine wave to go with the sine wave we recorded yesterday.
You may have cut in the middle of the amplitude peak.
First you must make the split at the zero-crossing point, which is where the waveform crosses the vertical centre of the waveform cycles.
What this does is ensure a smooth transition from one region to another and prevent the pops.
“But I’m not editing sine waves” I hear you say. This also applies to more complex waveforms as well. If you go into your DAW and zoom into any of your audio files, you will see a repeating cyclic pattern, even if it is not as define as a sine wave.
