[sdiy] Phase shifts and instantaneous frequency

[John Mahoney]

The ear can definitely hear things that aren't there, otherwise Waves MaxxBass (for example) wouldn't work. It... well, pardon their marketing pitch, but I'll let Waves say it:

"When you need to seriously pump up your lows, choose MaxxBass, the bass enhancement technology used on more hit records and major motion pictures than any other. MaxxBass uses psycho-acoustics to calculate precise harmonics that are related to the fundamental tones of sound. When these harmonics are combined, it creates the effect of lower, deeper frequencies. For bass you can really feel, it’s got to be MaxxBass."

It really does work.
