If you want to hear the effect of standing waves:
1) play a continuous sine wave (100-150-200Hz) through your monitors and move around in your control room. Notice volume changes as you move from mix position to a corner (or even moving your head in the mix position closer to ceiling or floor !!)
2) play a very slow sweeping sine, say 20Hz --> 500Hz over 30seconds and record it. Check out the result in your fav wave editor. What should be a continous sine wave just became a picture of the grand canyon !!
Phasing: More difficult. If you have a mixing desk with a phase button on it, it's easy: send identical signals through two channels and flip phase on one.
If you don't, try to find a function in your fave wave editor that says 'phase' or 'invert' or 'negative' or whatever...
Best done with the left and right channel of drum overhead tracks. Notice how some frequencies get cancelled and others pass through.
