How to use the EQ Practice Tool | iZotope Pro Audio Essentials

Hi.

In this video will take a look at the EQ practice tool, which you can use to improve your skills and ear training, and see how different areas of the spectrum affect instrument groups, and sound characteristics. Now that you've watched the videos about EQ. You'll recognize some of the features.

This is a straightforward EQ spectrum, similar to the one you might see in your plug-in or in your DAW. Frequency markers appear horizontally across the top, and amplitude is notated vertically on the side. Play one of the songs and drag the peak EQ points to listen to how your boots and cuts affect the sound.

We have limited the frequency and amplitude points to give you a few to play with, so that you can learn about EQ. We've chosen these points, because they're easy to hear, one compared to the next. When you start getting better at EQ, you can experiment on your own with your EQ tools, and experi

Types of EQ | iZotope Pro Audio Essentials

In this video, we're going to spend a few minutes talking about the different types of equalizers and their purposes.

Shelving EQ (0:10)

Let's start with an EQ type that you've probably used all your life, maybe without knowing it, the shelving EQ, look familiar? If you've ever turned up the bass or treble on your car radio, you've used something like this.

The name is descriptive. It looks like a shelf, with an entire range of frequencies being affected equally, above or below the frequency being affected.

Amplitude, Levels and Loudness | iZotope Pro Audio Essentials

Amplitude is the term we use when were talking about level. The vertical axis that you see on the right side of the spectrum shows the level or amplitude of a signal. A lower amplitude will be heard is quieter than a higher amplitude.

When were using an EQ to add amplitude and a certain frequency area, that's generally referred to as a boost. When we remove amplitude we call that a cut. You'll be practicing boots and cuts at different frequency points when you use the EQ practice tool.

The unit we use to describe amplitude is called the decibel or dB. Take a look at the meter on the right. You see a signal that sitting at -5 dBFS. Now I'm going to open up a fader like what you see in your DAW, and I'm going to turn the signal up, by 2 dB on the fader. If we look back at the meter, we now have a level of -3 dBFS. Let's go back to the fader. Now I will bring the signals down 3 dB, and you'll see tha

Connecting EQ to Musical Sound | iZotope Pro Audio Essentials

A music usually think in terms of the musical scale. When we mapped the frequency of musical notes, we noticed something interesting. As we go further and further up the scale the distance between each note is greater in terms of frequency. If we compare the distance between octaves, we have a very simple relationship: the frequency doubles with each ascending active. So we mention that the note A, commonly used as a tuning reference by classical musicians, vibrates at 440 Hz. The next octave higher is 880 Hz. The next is 1760 Hz or 1.7 kHz. So you see the distance in terms of numbers of frequencies increases as the notes get higher. Between 20 Hz and 20,000 Hz, we get about 10 octaves. You see this range in modern EQs, because it relates to the range of human hearing.

Fundamental and Harmonic Frequencies (1:02)

The note or the pitch being played by an instrument, is determined by the fundament

Understanding Frequency | iZotope Pro Audio Essentials

Hi everybody.

In this video, we're going to spend just a few minutes talking about frequency, looking at the spectrum, and listening.

First, here's a definition of frequency. Frequency is the speed of a sound's oscillation. It's what we hear as pitch.

A slower vibrating sound wave will sound lower in pitch, and a rapidly vibrating sound wave will sound higher in pitch. The unit we use to describe this vibration is hertz (Hz), that means the number of cycles per second.

A Word About EQ | iZotope Pro Audio Essentials

Welcome to the section on EQ.

If you want to get better at using equalizers, there are some things you need to understand about them, and that we were going to spend a few minutes getting down to basics.

The pros all know these basics so you should too. It will pay off for you later when we look at how to do things.

EQ you've probably used it all your life. There and many of the music players you use everyday. Your car stereo which has tone controls to boost or cut the lower high-end. Your phone or music player which has different presets for different types of music. You'll find them everywhere.
