EQ Ranges: Sweeping Frequencies (Formants) (2)

 

To get used to using EQ effectively, you will listen to various elements of the song "Nomadic Instinct" (download the mp3 file from here) and apply specific frequencies in boost and cut to find out which ones work for the specific instruments you are using. You are going to be asked to isolate individual instruments or groups of instruments, insert EQ processor into the audio track, and adjust the EQ parameters. 

 

1) Load in the song "Nomadic Instinct" into a Pro Tools audio track (*If you don't have Pro Tools, you can download its free version, Pro Tools | First, in here)

2) Identify the formants for the bass and snare in the song.

For each instrument listed in the table below, set one of the gains on a peak EQ to at least +8 dB. With just that track open set the bandwidth to narrow (high Q), and sweep through the frequencies finding the formant. You will know the formant frequencies because as you boost them, they will be louder than the other non-formant frequencies you have boosted. Write these frequencies in the appropriate columns in the table. (below table ) Cut or Boost these tones accordingly and EQ to make it sound its best.

*TIP: How to describe the quality of the sounds

When describing frequencies, you might want to use terms such as "tinny", "boomy", "hissy", "hum", "squeaky", "noise", "(instrument) leakage", etc.

Instrument Formant (Hz) Description of Formant Effect
Bass Low  40   Boomy
Bass Mid  80 Boomy (weight) 
Bass High  175  Clear Body
Snare Low  250  Bottom Boomy
Snare Mid  500  Clear Mid
Snare High  1000  Body. Clear sound

*Quick Reference Guide: How To Find The Frequency of Important Formants:

1) Select the range

2) Boost the range (lowest fc @ +8 dB)

3) Select narrow bandwidth (high Q)

4) Sweep the frequency range and listen for the formant
