Phase and time

Phase and time: Digital Audio Foundations
Phase and time: Digital Audio Foundations

Sound waves have a property called phase that refers either to specific parts of the cycle of rising and falling or the timing between 2 sounds. Complex sounds contain more than 1 frequency, and their shape is based on the phase and amplitude of those frequencies. When mixing complex sounds, out-of-phase frequencies tend to cancel and in-phase frequencies tend to reinforce. "Reversed phase" should be called "reversed polarity" because phase refers to changing the timing, not inverting the wave.
