Compression reduces the dynamic range of a piece of music. It brings the loudest points (that are over a certain threshold) down, so you can then bring the overall volume up.
Dynamics is the relative loudness or volume of the piece of music, and how it changes throughout the song.
During the 1940-1950's, someone would manually control the dynamics. Eventually something was made to control it automatically.
Compression works by monitoring an input and using the data to effect the output. It reduces the volume of the loudest points in the signal, so they loudest parts are closer to the quietest parts.
The ratio is how much you turn the loudest points down by.
A limiter is something that makes sure it doesn't go past the threshold.
Compression settings:
*Threshold- how loud the signal has to be before compression is applied
*Attack- how quickly the compression changes the volume. How long with a frequency stay over the threshold before compression is applied.
*Release- How long does it take the compressor to turn down
*Makeup Gain- when you turn the whole piece of music up, after applying compression.
