Anything which causes expansion esp. (Mech.) a tool for stretching open or expanding a tube, etc.
A dynamics processor which increases the dynamic range of a signal--basically the opposite of a compressor. Limited application in live sound, except when used as a gate.
A circuit to perform dynamic range expansion of an audio signal, usually in a logarithmic manner. The receive portion of a companding system.
Audio device that increases the dynamic range of sound by strengthening the loud sounds while weakening the soft sounds. Often used in conjunction with a compressor.
a compressor running in reverse
a dynamics control processor that lowers the volume of the signal when the overall level of the signal decreases
a dynamics processor that expands the dynamic range
a gentler form of noise gate which can help solve the chopping problem but does nothing to the noise embedded in signal
a more sophisticated form of gate
is a device or computer algorithm that reduces the level of a signal when it falls below a specified threshold in order to exaggerate its dynamic range.
An expander is another form of automatic level control. By attenuating the signal below the threshold, the expander reduces low-level noise or expands the dynamic range of the recorded material.
A device which is designed to decrease the level of low-level signals and increase the level of high-level ones, thereby increasing the dynamic range of the overall signal.
the opposite effect of compression is called expansion. Used to create an increased dynamic range of a signal.
A signal processing device used to increase the dynamic range of the signal passing through it.
an electronic device that increases dynamic range by reducing a signal's level any time it falls below a specific threshold.
A type of dynamic range processor which reduces the gain of audio signals which are under an adjustable 'threshold' level, therefore increasing the dynamic range. Generally allows the operator control over threshold, ratio, attack, release and 'hold' times. Both analogue and digital types are available.
An electronic device for increasing the range of dynamics of an audio signal.
In home audio, a device that increases the dynamic range of an incoming signal by making the loud passages louder and the quiet ones quieter. Rarely required with modern digital program material, expanders can make older recordings and video soundtracks that were compressed to accommodate analog-playback-medium limitations more realistic sounding. Some expansion circuits, like Dolby B, C, and S, as well as the dbx system still used in MTS video sound systems, are designed to work with signals that were previously compressed in a specific manner.
