Techniques For Dealing With Phase

Pro Sound Web: Phase is a constant concern for recording and mixing engineers. Problems with phase can ruin your music; it can be easily avoided or corrected, but first you need understand how the problem occurs.

This guide will attempt to explain almost everything there is to know about phase, what it is, how it happens, what it can sound like and some techniques to deal with it.

Phase and Polarity issues have always confused me a little bit. This is largely due to the fact that many audio practitioners use the words interchangeably. In fact it wasn't until the Sound Recording class I took last year where my professor made it very clear what the difference was. Even still it is confusing to diagnose phase versus polarity issues. Until now. This article is very descriptive and specifically outlines the differences between the two different issues and how they can be handled. It seems to me that phase is an easier issue to diagnose and fix because it can be handled with time delay. The one thing that confuses me still is the phase switch on most sound consoles. Does that switch merely change the signals phase 180 degrees or delay it. It is strange to me that a button on a sound console would effect the acoustic properties of the signal.
