How to Fill Your Mix's Frequency Spectrum

Understanding the Audio Frequency Spectrum

Are your tracks sounding thin?

It can be really disheartening. You put forth a ton of effort, feel like you're doing everything right, but the sound keeps coming up short.

Many times people will have the same types of instruments in a track, but it just doesn’t sound as full as the professional one they are referencing. So why is this?

Well, this can be for many reasons, such as:

• Sometimes it’s the mix in general
• Other times you may need additional effects on a track
• You may need different instruments in place for the song to sound full.   

First things first, you should have a general idea of what a frequency spectrum 

is comprised of.

The spectrum consists of low, low mid, high mid and high frequencies. These four can be wrapped up in the bigger spectrum of Bass, Mids, and Highs.

Each of these parts of the spectrum will consist of different synths, basses, drums and many more instruments.

It’s important to know where each instrument lives in the spectrum so you can know which part is missing if your song is sounding thin. 

Let's see how we can bring a track to life.
