In audio, the ratio of output level to the corresponding input level for a device. Level is typically represented in terms of power or voltage, but gain is unitless and is identical whether voltages or powers were used to calculate it. Because gain is a ratio, it is usually described using decibels. A gain of 0 dB indicates no change in level, while a gain of 10 dB is perceived as approximately a doubling in loudness—depending on the nature of the sound and on the initial loudness.
Industry:Software; Computer
In audio, the range, expressed in decibels, between a standard reference signal level and the maximum allowable signal level (the ceiling). See also dynamic range.

(1) In electronics, the amount of opposition a circuit presents to an AC (alternating current) signal at a given frequency. Impedance includes both a resistive (frequency-independent) and a reactive (frequency-dependent) component. (2) In acoustics, the ratio of average sound pressure to particle velocity over a given surface area and at a given frequency.
Industry:Software; Computer
An operation that changes the scale of the coordinate space by the specified x and y factors, effectively stretching or shrinking coordinates. The magnitude of the x and y factors governs whether the new coordinates are larger or smaller than the original. A negative factor flips the corresponding axis.
