Course Description

We can describe mastering as the final process in audio and music production. In this stage, we optimize the track's mix and final volume to get a professional result. Mastering can improve the quality of a music production and get it ready for commercial distribution. This could be done for CD, TV, the Internet, video games, etc.

"A way of maximizing music to make it more effective for the listener as well as maybe maximizing it in a competitive way for the industry." -Bernie Grundman

"Mastering is the last creative step in the music production process, the bride between mixing and replication.. -Bob Katz 


Mastering aims to make your audio sound properly on any kind of audio system, device or application (home system, earphones, club, theaters, etc.). A well-mastered song will have the right volume, avoiding those unpleasant volume changes from song to song. Mastering also brings more clarity and punch to the music, so it can compete with other professional productions.

In this new course, you will learn the most common audio processes for mastering music. The concepts learned in this course can be applied to any kind of audio project. All this knowledge comes from the experience of great mastering engineers, like Bob Katz, Greg Calbi, Bernie Grundman, Bob Ludwig, Doug Sax, among others.

With practice and patience while following the recommendations, you will get better results each time and your music will sound more professional and well-finished.

A course designed for a step-by-step approach

This course has been designed to be clear and effective. Each lesson explains the most important topics related to music mastering in a clear and direct way. You can study a couple of lessons in just 15 minutes each day! It takes you in a step-by-step process, from file selection to audio bouncing for CD or web platforms (Apple Music, Spotify, YouTube, etc.). The lessons include topics like:

  • Monitoring considerations

  • Audio file Editing and noise reduction

  • Equalization techniques

  • Dynamics processing

  • Serial, parallel and multiband processing

  • Compression techniques

  • Control and balance of stereo image

  • Stereo L-R vs M-S processing

  • Use of reverb and harmonic enhancers in mastering

  • Limiters and levels for CD and streaming platforms

  • Loudness, LUFS and dBs

  • Dithering

All these techniques can be applied on any music style: Pop, rock, latin, hip-hop, EDM, urbano, ballad, country, etc. The information in the course is also valuable for other kinds of audio productions, like:

  • Video game audio

  • Audio for Video

  • Podcast production

  • Audio for mobile or web Apps

  • Multimedia


At the end of the course, you will get the knowledge and examples to start mastering your own songs and music productions. You will know how to use your available audio plugins (VST, AU, AAX, etc) in a mastering setup.

You only need any DAW (Logic, Pro Tools, Cubase, Ableton Live, etc.) and its native processors (plugins) to get started!*

Current students comment:

"A very complete course. Perfectly explained, there was no need to review again one lesson since it is explained on detail with visual examples and documentation. It is important that you must practice to improve your ear and be able to fully master the audio mastering." Daniel Hurtado

"This was just what I was looking for. I got a clear basic picture of what is the mastering process order and tools for it. Now it's up to me to start using it in practice, but at least I have a good basic course done as a foundation." Juha Mäkelä

"I am blown away by this course! By lesson 12 and using 12-year-old Garageband 09', I have been able to improve the quality of my very amateur indie tracks that I plan to release after this course." Lake Smith


You will be guided by a certified audio instructor, with more than 20 years of teaching experience at all levels, from seminars to college-level classes and a top instructor on Udemy, so academic quality is guaranteed. Join more than 20,000 students worldwide and learn more about audio!

Great and to the point. Ive been mixing audio for 20 years and while you always think you know something going back to the fundamentals and keeping things simple never gets old. Worth it for the null check limiter tip! That is such a clever way to hear what a processor is doing. You could do that technique for ANY plugin really. Will watch his other series.

By James Larsen on 12/4/2025

The course was very informative and it was structured logically and clearly. The information was easy to digest. The subtitles on the other hand were really bad and at times said the opposite of what was implied. It would be better to have no subtitles if they dont communicate correctly what the teacher is saying.

By Michael Turner on 11/30/2024

VERY GOOD VERY INFORMATIVE WILL NEED MORE COURSES LIKE THIS TO BE ABLE TO REPRODUCE MY OWN MASTERS BUT AGAIN VERY GOOD VERY CLEAR THE TEACHER HERE DOES NOT OVER TALK OR TALK TO MUCH HE IS RIGHT TO THE POINT, I MUST SAY HATE THE QUIZZES BECAUSE IT IS TOO MUCH DATA TO RECALL ON ALL OF THE PROCESSORS BUT THAT IS DUE TO MY IMMATURITY AND NEW UNDERSTANDINGS

By Braulio Silva on 6/27/2023

1-10 of learning, I hit a 9 for sure. I'm fairly good at mixing but mastering was the last push I needed. Marco certainly does a great job at showing the stages of mastering, start to finish, and explains why they are necessary. However, it should come as no surprise to anyone that you will need to invest in the required tools to complete most of your master. I think the range of this course is very broad in what it covers and will expand your musical mentality. Gracias por tu ayuda Marco, si se puede perro!

By Dan Lukens on 12/23/2022

I wanted to learn mastering because I can mix pretty well but my mixes lack that extra quality that mastered songs have and my mixes don't always translate well to different systems. There were a lot of things in this course that I understood completely but there were also some things that I will need to go back and repeat those sections over and over until I completely understand them but overall, I thought the course was more informative than any other information I've been able to find about mastering over years and years of searching online and buying books.

By Stelios Mimilakis on 7/26/2022

It is too empirical for a course. Even for the nature of audio mastering, there should be at least multiple music examples from various genres, instrumentation, etc.

By Battee Seyou on 2/13/2022

Great contents, as a music lover who has no idea on mastering I find this class enjoyable. I feel like you should of walked your students through the mastering process on the; what to do first, what to look for, I mean visually. I what to learn the concept but without the too much unnecessary lectors, straight to the point. Thank you for the knowledge, it was beautiful.

By Arto Schroderus on 12/20/2020

Waiting for the good stuff. So far we have heard about basic recommendations, which is good be highlighted but I am sure it gets more interesting from here onwards.

By Colin Grist on 12/6/2020

Excellent! Very well presented with very clear explanations of the topics. I am a relative newcomer to digital music recording and I found the course easy to understand. Definitely recommended.
