About This Course

Published 8/2016 English

Course Description

Do you know how to use equalisers?

Do you understand audio frequencies?

Do you understand hearing damage and how to prevent it?

Are you a budding audio engineer?

Are you a musician?

You need this course! Don't be intimidated anymore by mixers, equalisers and sound engineers. 


In this course you will learn:

  • how humans hear
  • what hearing damage is and how to prevent it
  • how to identify any frequency
  • how to eliminate feedback
  • how to make instruments and tracks sound full using 'timbre'
  • how to use all equalisers (single band EQs, parametric EQs, graphic EQs)
  • selective vs subtractive equalising
  • how to 'ring out a room'

As a bonus you'll learn all about psychoacoustics - the manipulation of sound to 'fool' the brain.

Section 1: How Do Humans Hear?

Everything in this course is based on hearing - how and why do we hear? Our biology determines our experience of sound and this lecture forms the basis for understanding of more complex audio principles.


This lecture explains the limits of human hearing - both in volume and frequency. It also explains the most common phenomenon musicians and sound engineers experience in live settings - threshold shifts.


Exceeding the volume limits of human hearing does permanent damage. This lecture explains how damage is caused and how to avoid it.

Section 2: Frequency Recognition

In this lecture, learn how to identify frequencies accurately - a skill you need for the first exam.


This is the first interactive exam where you can test your ability to identify frequencies.


The scariest and most annoying sound you can hear in a live setting. FEEDBACK! What is it and how do you prevent it?


This lecture introduces you to the secret training weapon of any good audiophile - the feedback trainer.

Section 3: Timbre

This lecture demonstrates the magic of Timbre - the quality that makes sounds rich.


The first element of timbre is harmonics - learn why every sound has multiple frequencies.


This lecture overviews the frequency range of instruments and how you can leverage it to hide or show off an sound.


The second element of timbre - attack. Learn why attack is the most important identifying quality of a sound. Also experience the confusion of sounds with the attack removed.


The third aspect of timbre - shimmer - ensures sounds are alive. Without it, sounds die.


The fourth aspect of timbre - sibilance - covers the most important frequencies of all for the human ear.


This lecture is an overall guide to frequency bands - how to target them for the desired effect.

Section 4: Equalisation (EQ)

To adjust frequencies we use equalisers but there are many types. In this lecture, learn which ones to use.


A common misunderstanding with equalisers is the difference between raising some frequencies and raising all frequencies. Learn the difference in this lecture.


In this lecture learn the technique of selective equalising with live demonstrations.


This lecture covers the more advanced and less well-known technique subtractive equalising.


Using your EQ skills, you can now 'ring out a room' to make it feedback proof. Learn how in this lecture.


In this interactive exam you will be practising your frequency identifying skills.

Section 5: Psychoacoustics

Now that you understand the science of frequencies, it's time to learn how to apply this knowledge in manipulating the brain and its perception of sound.


In this bonus lecture you'll be visiting the virtual barber shop - a famous auditory experience.


In this lecture, learn just a few tricks that Hollywood uses to make explosions sound louder than they are.


In this lecture we apply psychoacoustics to an audio track to transform a mono track to stereo.


This lecture shows more psychoacoustic techniques that you can use.


Most people talk in psychoacoustics, not frequencies: "it sounds warm, it sounds tinny, it doesn't shine..." Here is the cheat sheet to what frequencies they are referring to.


This is the final exam where you can use these MP3s to practice psychoacoustics. This is the ultimate in frequency manipulation - the type of adjustments you will be making in real life.

Instructor Biography

Matt Wong, Super Multi-Tasker (Pilot, Lawyer, Medical Entrepreneur)

I founded and ran a high end medical clinic for 8 years in Sydney, Australia. We spearheaded the introduction of genomic testing to the public and publishing house Penguin Books commissioned a book documenting these exploits for release in 2015.

I also created a nut manufacturing business that makes 'the best nuts on earth'. I qualified as an aircraft pilot in Sydney, trained as a lawyer at the University of Technology Sydney, and spent years leading teams both corporately and for community groups. I trained at the Australian Institute of Music - Classical Guitar, but secretly love playing the piano.

I have a 'hungry brain' that is addicted to learning, thus the lawyer/pilot/musician/manufacturer/medical entrepreneur qualifications. I believe one career is not enough. We have the ability to be much greater than we are, so don't settle; grow!
