The Audio Masterclass Professional Course in Equalization

This course covers all of the processes of equalization that are in regular use in recording studio operations. The twelve modules cover filters, parametric and graphic equalizers and acoustic equalization. Applications of EQ include individual instruments and voices, blending instruments in a mix, and the equalization of a completed mix.

The course is entirely practical and is assessed solely on the learner's practical assignment work. Text and graphic support materials are provided as appropriate, and the course includes audio example files demonstrating equalization techniques.

The outcome of the course will be an enhanced level of knowledge, skills and experience in equalization techniques.

Flexible Learning
You can study the Audio Masterclass Professional Course in Equalization online or by downloading all of the course materials to your own computer. The course can be completed in 12 weeks, or you can spread it out over up to two years if you wish. You can work on the course at any time you choose, and take breaks whenever you like.

Each of the twelve modules of this course includes a practical assignment project that you can work on in your own home recording studio using digital audio workstation software. The assignments include tasks that are typical of a professional recording environment. The challenges are tough, but full instruction is given, often with audio examples and demonstrations.

Study Methods
This is the fully-assessed version of the Audio Masterclass Professional Course in Equalization. Study centers around the practical assignment projects of the course and the assessments you will receive.

You can submit each of your twelve practical assignment projects to Audio Masterclass for our assessment, comments and advice. Our assessments are detailed, friendly and helpful. We will tell you exactly what you are doing right, what could be better, and how you can improve. Re-submissions are welcome.

You will receive the Audio Masterclass Professional Certificate in Equalization on successful completion of the course.

What our students say about Audio Masterclass courses

You did a great job!

Excellent material, audio and videos are really good and clear.

I appreciate the depth, very informative and useful. I increased my knowledge in the area I am so passionate about. I was able to implement a lot of new procedures in my own sound and musical projects.

My gratitude and best regards

Anton Strecky, Slovakia

With my employment in health service established years ago, music and recording is an essential withdrawal from professionalism to me, rather than a significant possibility to provide a supplement to earned income. But with growing interest and investment, achievement of professionally acceptable quality became a must. At that point studying at Audio Masterclass had only pros and no cons to me, and no equally accessible alternatives of world-class standards.

The book "How to set up a Pro Home Recording Studio" [by Audio Masterclass] and other information concerning hardware and software helped me to find "my way" in the jungle of possibilities, and it actually had a money saving effect.

Assessments of practical assignment projects were of especially great importance to me. It is easy for the beginner like me to have an illusion that the produced work is good, while actually it is not. Additional valuable information can be derived from individually provided comments too.

It is very comforting to have tons of audio examples at hand. Even after the course I use some of them as benchmarks of specific quality.

The most special experiences along the way of the course were moments of approaching the presumed limits of creative possibilities… stepping beyond… and finding that there is something more out there. And this kind of training may have implications that are not immediately obvious, but may prove to be of great importance in any intellectually demanding/competitive situation of life. All in all, I consider that to be my greatest gain achieved at Audio Masterclass.”

Hi David [Gatis refers to David Mellor, Course Director of Audio Masterclass], I very happy that I signed-up for your course and that I've graduated it!

Actually, before I made my mind, I did a lot of research on web about your course, because at that time I just finished my studies at America Audio Insitute, but I felt like it's not enough for me to get on next level - as I wanted it so much. So I found Audio Masterclass. I found just one review on google, where somebody told that: "you won't get what you as an engineer really need etc, it lacks of deep dive in subject... this and that...." - I thought to myself: "well... maybe this guys is all wise or he is not opened for new experience and knowledge, or he was a bad student". So I decided to take a risk as I had no clue what is will look like.

The first thing that made most sense to me is practical assignment - that is "everything"! But in many other online-schools (like America Audio Insitute or Detroit Recording institute), it's the biggest defect of the program. If you can send your material for constructive feedback, it's the most valuable learning point!

Next thing: Every time I got feedback on task, at first I started learn it with your written feedback - that had greatest value to me. Another great thing is that by reading your feedback, you really get this feeling that somebody is listening to your work and paying attention to details.

About content: the structure of the course is very similar to many other courses but the difference in content is huge! And by this I also mean the language - how you explain things and details. This is very important to me as I'm not comming from english speaking country, but here it's easy to perceive the information. There are many great recording engineers out there, but not everyone has capability to teach others - but you can teach! (and I mean it, especially if I compare with my previous courses on America Audio Insitute Detroit Recording institute).

Other student audio examples: - very good in understanding what to do, and what to avoid! Sometimes if you have nothing to compare your work with, then you might think that "oh, yeah, great record!", but when you start to listen to others ...hmmm.... it become a challenge - it's like setting benchmark.

And yes, for me, as a small studio owner, has no huge budget or possibility to try out some top-end mics, the files with pre-amp and mic samples are awesome - now I have an idea how U87 sounds! : )

About improvements - actually I don't have anything to add to this, because from all this course I can feel that it's all made with professional attitude.

Overall - I've learned a lot, but most important to me is that by having many "aha" moments, I've developed completley different mindset when I start to think about recording, mixing and mastering - for me, it's the biggest achievement! ...and I want to learn more!

Ok, again, thanks for everything - I got the certificate - it's a very important milestone for me towards my GRAMMY! : )

P.S. I've already decided, to save some money and enroll to your professional courses within few month, so see you soon!

P.S.S. I've also attached my picture from my home studio.

All the best.
