Line 1: Line 1:
−
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.

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.

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.
