Earlier in the blog you mentioned “phase cancellation” as one of the reasons why bassline may sound flabby and not punch enough. Could you explain that please?
Let’s take a simple audio sample. I’m going to use a kick drum from some sample library. Just a regular kick, nothing fancy:
Now I’m going to duplicate the channel, add Utility tool to reverse the poles of the phase, and flatten this channel into a new piece of audio. Here is what’ve got:
Take a closer look at the waveforms: their peaks go in the opposite way. And now listen to what happens when I’ll playback both of these samples at the same time:
No, your speakers are fine. The result of these two samples playing together is silence — no sound, literally. This is what called a phase cancellation.
Typically, in the real production, your sounds’ phases won’t be exactly the opposite causing silence like in the example above, but even a subtle miss-phase will cancel some frequencies out. You should keep it in mind especially when dealing with a low-frequency signal such as bassline.
Watch also this excerpt from Lynda course. It demonstrates phase cancellation of an acoustic signal but the principle applies pretty much in every production:
