Document Summary

Phase: measured in degrees refers to a part of the cycle a sound wave has reached at a given point in time, used to compare the timing of different waves ie. phase shift to the left/right. Complex sounds: complex sounds can be treated as a collection of simple sin waves added together, fundamental frequency the lowest sinusoidal frequency in a complex wave, harmonic frequency sine component of a complex wave frequency that is an integer multiple of the fundamental frequency, numbered in order of distance from the fundamental, ex. Fourier theory: mathematical procedure that helps us break down complex sounds into their sine wave components, fourier spectrum, decomposed into magnitude and phase spectrum, representation of the magnitude of the individual frequency components in a signal (cid:224) magnitude spectrum, phase spectrum, representation of the relative phases of individual frequency components present in a signal, fourier synthesis allows you to perfectly reconstitute the signal from its magnitude and phase components.
