Compression is a difficult topic to cover, and often many producers struggle to grasp the capability and an effective use of compression.

What is compression?
When should you compress?
How do you even compress?
What is Dynamic Range?
What is Uplift Compression?
Why Do Attack & Release Matter?
Why Use Gain-Compensation?

These are only a few questions and topics that are covered below. I highly suggest reading these articles, as they are imperative to having a concrete understanding of compression in its entirety.

Two articles which were essential to my knowledge, understanding, and application of compression in my mixes were written by Mike Senior and Hugh Robjohns from SoundOnSound. Below is a link to these articles.

If you have your own articles or any relevant information, feel free to pass it along and I will modify the table of contents for quick and easy access to all those who are interested.

** I was debating to make an entire table of contents and compression guide, however I feel as if this information is so readily available via Google searches, so it may be redundant.

I have a Word document of nearly every compression article I have ever read.. If you think it is a good idea, let me know and I will gladly put in the work to collect and organization all relevant compression information, and will even make a concise organized list of all relevant compression tips, tricks, and threads on TPF.
