Understanding Compression

Understanding Compression

So I keep reading and I keep forgetting. Today I re-read the technical aspects of how to control a compressor from this article:

Understanding Compressors and Compression

Now it all makes sense, except for the part where quiet sounds become louder.

Is it all in the makeup gain? I read through each of the controls here and could not find what function increases the volume of the quiet sounds?

I'll try to find another source, but in the meantime, any insight?

yeah, it's pretty much in the makeup gain. the compressor basically "levels" or evens out the loud parts, so that the overall dynamic range is less- there's less difference between loud and soft- and then you turn everything up. so the loud parts are the original volume, the medium parts are almost as loud as the loud parts, and the quiet parts are easily audible.

you know. on a basic level.

the tricky part is that it doesn't just make quiet things easier to hear- it can also change the balance, the eq spectrum, "how well" it cuts through the mix, and any number of other subjective things.
