Compressor Patch

The Compressor patch reduces the volume of loud sounds or amplifies the volume of quiet sounds, thus reducing or compressing an audio signal's dynamic range. Use this patch to help even out the loud and quiet parts of audio clip or other audio source, so that both can be heard more clearly.



The audio source that you want to alter. Attach to an audio clip, microphone or other audio source.


The level above which the compressor begins to act. A threshold of -12dB means you would only hear compression on sounds louder than that.

Attack Time

This is the duration of time it takes for the compressor to act on the unprocessed signal, once the threshold had been reached.

Release Time

This is the duration of time it takes for the signal to decay to its unprocessed level, once the audio had fallen below the set threshold.

Hold Time

This is the duration of time the compressor acts on the signal after the attack time has passed, and before the release time begins.

Lookahead Time

The amount of time to delay the signal before applying the calculated compression attenuation.


How aggressive the dynamic range compression is. A ratio of 3 means for every 3dB of signal above the threshold, only 1dB passes through.


How smoothly the transition to the attenuated level occurs--larger values will result in a more gradual change, and smaller ones will result in a more abrupt one.

Input Gain

This controls the amplitude of un-effected signal fed into the compressor.

Output Gain

This controls the amplitude of effected signal coming out of the compressor --raise this level to hear changes to the audio.


Disable this processor while still allowing unprocessed audio signal to pass.



Audio output. Connect to a speaker an audio effect ot another patch that has an audio input.
