The stage that a particle in vibration has reached in its CYCLE. Particles are in phase when they are at the same stage in the cycle at the same time, and out of phase when they are at opposite stages. Phase is measured by the angle of rotation, in degrees or radians.
Also called flanging or flangeing. An effect created by adding together two identical SIGNALs separated by a very short time delay (less than 25 ms, but strongest below 10 ms). These short delays are within the audio WAVELENGTH range, and the combination of the two signals affects the frequency SPECTRUM of the composite sound.
For any PERIODIC wave the wavelength is the distance from a given point in the wave to the corresponding point in the next cycle of the wave, frequently represented by the Greek letter lambda. It may also be thought of as the distance the sound travels in one CYCLE or PERIOD.
An ordering of a system of PITCHes, usually in ascending FREQUENCY order. The distance between any two pitches or NOTEs is called an interval.
