What is downward expansion?

Downward expansion is the most common expansion used in pro audio and recording. This type of expansion applies noise reduction to all signals below a set threshold level.

What is upwards expansion?

Upward expansion is akin to regular old compression in a key way: it affects a louder signal as it crosses the threshold. However, instead of clamping down on the signal, the expander pushes the sound up in level. ... So if your compressor can give you a ratio of 0.5:1, then most likely it's expanding at that point.

Is upward compression the same as expansion?

Well, as we've discussed, upward compression brings the audio signal below a set threshold up in level by a set ratio in order to compress dynamic range. Expansion, on the other hand, brings the audio signal below a set threshold down in level by a set ratio in order to expand dynamic range.

What is upward and downward compression?

Downward compression reduces the volume of loud sounds above a certain threshold. ... Upward compression increases the volume of quiet sounds below a certain threshold. The louder sounds above the threshold remain unaffected.
