Compression

-Automated level control

-using input signal

-to determine the output level

-set the compression by using threshold and ratio

“A threshold control determines at what signal level,the compressor will begin to operate”

Most compressors have ATTACK and RELEASE parameters.These controls determines,how fast or slow the compressor reacts to the beginning (Attack) and end (Release) of the signal.

When a compressor operates,it decreases the gain of the signal,so…there is another control called  “make-up gain”,which is used to boost the signal to it’s original level.

“EVERY 4 dB THAT GOES INTO THE COMPRESSOR,1 dB WILL COME OUT, FOR A RATIO OF 4:1”
