NOTE: If you purchased the original version of Compression Explained, log in now to download the new version for free!

This series sets out to explain what compression is, how compressors work, and how to use compression in sound design, mixing, and mastering.

Daves videos highlight using native and DSP-based software compressors, as well as hardware compressors, so you can use this information with any DAW or hardware compressor unit.

Dave starts out with a primer on the basic components of an audio signal, which leads into an explanation of the basics of dynamic range. After that, Dave offers a brief history of how compression developed into the staple of audio production it is today.

Next, Dave explores the kinds of compressors in use today, and the electrical components that control them, as well as the components the software versions emulate. That leads directly into videos on the specific controls common to most compressors: threshold, ratio, and makeup gain.

Dave now covers the more creative compressor controls by showing you how to shape your sound with various types of envelope controls. He reveals the different knee behaviors, where the threshold meets the compression ratio, and explains how you can control your compressor using a different signal via the sidechain input.

Dave continues with a video on alternate compressor types, such as multiband compressors, upward compressors, and limiters, as well as how you can stack compressors using parallel or serial compression.

Finally, Dave wraps up the series with videos showing you how to apply everything youve learned. He shares his approach to mixing with compression, and what goes into his decision making process. Then he shows you how to use compression when mastering audio for final release to the world.

Knowing how to use compression can be the difference between a muddy and dull sounding mix or a polished and exciting one. If youve ever wanted to master these vital dynamics techniques, watch Compression Explained today!

Wonderfully informative tutorial from Mr Askew

I've done a few of Dave's tutorials - mostly related to Cubase and in a very short timeframe these complex technologies have transitioned from being tedious foes to becoming old friends. He has a perfect blend of knowledge depth and experience, the ability to convey complex ideas and the energy to make it compelling. In this series the graphics are very well done and really work for visual people. As I progress through this course I am starting to feel very comfortable with the 'dark art' of compression. Finally, after years of messing around and confusing myself with conflicting 'Tube clips and forums, I'm feeling like I'm getting somewhere here. I am very impressed and highly recommend this course.

Very good

Deep background knowledge about compression. Sadly the last parts about mixing and mastering with compression where a little hasty. I would have appreciated going more into detail there. That why I give it 4 of 5 stars.

An absolutely excellent series

A great series of lessons on compression and its uses. This series of lessons is good for all levels of engineers from beginners to experts. There are so many techniques described in this series, I would say it's a must for anyone wanting to understand how compressors work, and the techniques involved in using them. From FX, to mastering, this series covers a huge range of subjects. Make sure to have your audio coming out of something better than Laptop speakers so you can really hear what is being demonstrated

1. When did you start dabbling in music?

I've been a musician since a very early age starting with playing the trumpet, guitar, bass, and piano. Not the drums though, my brother got those genes. I am an excellent finger drummer though to say the least!

2. What training have you had?

For formal training I took regular music lessons in grade school and high school which were fortified with training from private tutors. After school I joined the Army band and went through the Army School of Music as well. I'd like to say that most of what I've learned though came through experience and having hands-on opportunities.

3. When did you get into recording?

During my stay in the Army I was the live sound manager. I loved operating the mixing board but I loathed the 'live' environment. I truly enjoyed making things sound great but I didn't like the fact that there is so little room for error in the live setting. I had wished for more time to invest in being able to make something that sounds ok, turn into something phenomenal. I started by recording our Army band performances on a Yamaha AW1600 for fun, but really enjoyed that I could capture that moment then take my time to make it sound amazing without having to worry about the crowd booing. The rest is history!

4. People you have worked with/for?

A few musical highlights have been running live sound for the President of the US, and doing some on the side tech work for the band Dope. I also was able to work with Virus on one of his side projects. Over the years though my focus has been mainly in customer service and tech, so I've talked with thousands of industry professionals on a daily basis which have truly been too numerous to name individually.

5. Why are you so good at training people?

Growing up I always felt that I spent a lot of time training myself how to do things, but oddly enough I always thought I'd never make a great teacher even though I'm a geek through and through. In the early part of my career I turned down so many opportunities to teach music and engineering. I think part of that came with my own insecurity of not having the formal education that society tells us that we need to succeed. It took a lot of time, practice, and personal education to get me past that hump of feeling confident in trusting that what I taught myself was legit. I've finally reached a point where I feel like I have a lot to offer in terms of knowledge, but most of it has come through investing the time with having the hands on experience that not even formally educated people get sometimes. I truly believe the best way to learn something is to get your hands on it and immerse yourself in every little detail. Groove 3 is a great avenue to be able to share that knowledge.

Rated 3.0 out of 5 by from i don't think this was taught exceptionally iwell Is there a subtle art to teaching? Do different students have different perceptions of what artful teaching is? Bottom line: I don't think this course was conveyed well. It is difficult for me to say this because aesthetically/transitionally it was very well put together...but what else can I say- this guy didn't really convey the information well (in my opinion). Some good fundamentals were laid down on compression though. But a lot of it dragged for me. (i have been home recording for one year (using Logic Pro X), i am by no means an expert. I am an amateur (heavily devoted, but no professional training))

Rated 5.0 out of 5 by from One of the best explanations of compression I'm one of those people who has struggled with compression for years. Yes, I understand how the controls work... but how, why, and when do I actually use compression? This video series helped me out big time. Here was the key insight for me: it's all about keeping the quitest sounds above the noise floor, and the loudest sounds below digital clipping. So imagine you have a recording that has a whisper sound, and a train going by. If you increase the level so the whisper is above the noise floor, the train sound is going to be clipping. But if you lower the level so the train sound isn't clipping, then the whisper sound is going to be drowned in noise. Compression to the rescue! It was in the first few videos here that compression clicked for me – finally! Then the instructor shows examples of using compression to modify bass sounds, drums, and complete mixes... very very useful.
Date published: 2016-09-03
Rated 4.0 out of 5 by from Thorough, but... This tutorial series is very thorough, but when you teach what attack means you're not entirely correct. Attack is not how long the compressor waits to start reducing gain. Attack is how long the compressor takes to reduce the gain. Gain reduction is happening from the moment the threshold is crossed, and the attack time is how long it takes for the reduction to complete. An attack time of 15 ms means that as soon as the sound crosses above the threshold, it will take 15 ms for the sound to be pushed down. It doesn't mean that it will wait 15 ms to begin reducing gain.
