This is where a channels dynamics settings can be altered. Each channel has two dynamics processors which can be inserted. One is a 'gate type' and the second is a '[[Compression]] type'.  
+
Not to be confused with data compression common in .mp3s, compression as used by Engineering refers to the compression (or reduction) of the dynamic range of a signal. Most basic compressors have a threshold, ratio and make up gain control.  
   −
Both dynamics processors are parametric, which means that parameters such as attack, hold and release time (measured in milliseconds) can be adjusted. Not every compressor/gate will let you do this.
+
'''Threshold'''
 +
 
 +
The threshold is where, above a certain level of loudness, such as -18dB (where 0dB is maximum relative loudness) the compressor begins reducing the dynamic range or maximum peak values of the audio signal.
 +
 
 +
'''Ratio'''
 +
The ratio is how hard a compressor works to reduce dynamic range above the threshold. With a threshold of 1:1, the Compressor does not do anything to the audio signal.
