An automatic volume limiter system (AVLS) is an option that limits the maximum volume level and is enabled through software or hardware in stationary or portable media player devices used with headphones such as the Walkman or Sony PSP. [1]
Most devices capable of compressing audio dynamics can also be used to reduce the volume of one audio source when another audio source reaches a certain level; this is called side-chaining. [13] In electronic dance music , side-chaining is often used on basslines , controlled by the kick drum or a similar percussive trigger, to prevent the two ...
The visual indicator on the limiter works most commonly on a “traffic light” system: green = no problem, amber = sound levels approaching the threshold, red = threshold breached. If the light stays red for more than a few seconds, then the limiter will take action and cut the power.
The Fairchild 660 is a tube-based single-channel audio compressor invented by Rein Narma and manufactured by the Fairchild Recording Equipment Corporation beginning in 1959. The 660 was the first intelligent automatic volume control limiter. [1] The Fairchild 670, introduced shortly after the 660, is a dual-channel version. [2]
For loudness compensation to work correctly the playback system must also accurately assume what volume level was used in mastering. For movie soundtracks this reference volume level is an industry standard [ 4 ] and can be used by manufacturers to provide a loudness feature that works with a reasonable degree of accuracy.
An Alesis Micro Gate noise gate. A noise gate or simply gate is an electronic device or software that is used to control the volume of an audio signal.Comparable to a limiter, which attenuates signals above a threshold, such as loud attacks from the start of musical notes, noise gates attenuate signals that register below the threshold.
