The Italian word for "echo"; an effect in which a group of notes is repeated, usually more softly, and perhaps at a different octave, to create an echo effect égal (Fr.) Equal eilend (Ger.) Hurrying ein wenig (Ger.) A little einfach (Ger.) Simple emporté (Fr.) Fiery, impetuous en animant (Fr.) Becoming very lively en cédant (Fr.) Yielding en ...
The frequency of a sound is defined as the number of repetitions of its waveform per second, and is measured in hertz; frequency is inversely proportional to wavelength (in a medium of uniform propagation velocity, such as sound in air). The wavelength of a sound is the distance between any two consecutive matching points on the waveform.
A synonym for distortion. With vocals, acoustic instruments, front of house mixes, and monitor mixes, clipping is almost always deemed to be undesirable, and it is minimized by reducing gain levels, using compression devices, adding "pads" (attenuation circuits), etc.
Because amplitude varies directly with sound pressure (A = k 1 P) and sound pressure varies directly with distance (P = k 2 d), such that amplitude also varies directly with distance (A = k 1 (k 2 d) = k 1 k 2 d), the amplitude of the sound as perceived by the listener will be greatest when the speaker is at the point in its rotation closest to ...
A distinct use of the term sound from its use in physics is that in physiology and psychology, where the term refers to the subject of perception by the brain. The field of psychoacoustics is dedicated to such studies. Webster's dictionary defined sound as: "1. The sensation of hearing, that which is heard; specif.: a. Psychophysics.
Using this technique, the audio data is stored as a sequence of fixed amplitude (i.e. 1-bit) values at a sample rate of 2.884 MHz, which is 64 times the 44.1 kHz sample rate used by CD. At any point in time, the amplitude of the original analog signal is represented by the density of 1's or 0's in the data stream.
In these cases, the waveform is an attribute that is independent of the frequency, amplitude, or phase shift of the signal. The waveform of an electrical signal can be visualized in an oscilloscope or any other device that can capture and plot its value at various times, with suitable scales in the time and value axes.
The concept of wavelength is most often applied to sinusoidal, or nearly sinusoidal, waves, because in a linear system the sinusoid is the unique shape that propagates with no shape change – just a phase change and potentially an amplitude change. [15] The wavelength (or alternatively wavenumber or wave vector) is a characterization of the ...
