level and cuts it off when it drops below that level.<br />
Imagine you play a chord on your guitar, which is connected to a noise<br />
gate, which is then connected to your amp. The noise gate 'sees' a<br />
decent signal level and lets the sound through. You then damp the<br />
chord off with your hand.. The noise gate sees the signal level drop<br />
and cuts the sound off. If the gate weren't there, you'd still hear<br />
all the low level stuff like hum, the sound of your hand sliding on<br />
the strings, the sound of the guitar clanking against your belt<br />
buckle. As soon as you play a note, the gate 'opens' and you hear the<br />
guitar again.<br />
Q2.5 What is (upward) expansion?<br />
marcl508@hudson.iii.net (Marc LaFleur) writes:<br />
Upward expansion is the inverse of compression. Where compression<br />
decreases excessive peaks over a threshold, upward expansion decreases<br />
excessive troughs below a threshold. As the signal falls below a<br />
preset lower threshold, the gain is scaled "upward" by the set ratio<br />
(e.g. an input signal falling below the threshold by 10dB would be<br />
boosted to 5dB below the threshold with a ratio of 2:1).<br />
