Microsounds
Open the tutorial.
We usually use the noise gate to keep from amplifying things that should not be heard when compressing. Sometimes these in-between sounds are very interesting in themselves. I like to record very tiny sounds, like the ticking of a mechanical stopwatch. When doing that, I use quite a lot of compression to bring up the ting of the spring while keeping the grind of the winding at a reasonable level. The patcher C8mMicrosounds is set up for this. Compression is applied to signals that are below the threshold, and signals above are unchanged. This leaves the notes essentially alone, but the sounds between the notes are brought out. (This is how a guitar sustain pedal works.) Of course there is a lot of junk at very low levels we don’t want to hear, so the patch has a second threshold; levels below this threshold are unaffected.
Expansion
The C8mMicrosounds patcher has one more trick. The ratio can be set below 1:1. Fractional ratios give expansion, where soft sounds are made softer. This can restore tracks that have been over compressed, or separate out the loudest sounds in a pattern.
