Apply Filter Curve EQ in Audacity

Mike Russell·Oct 2024

Demo summary

The demonstrator walks through opening the Filter Curve EQ, setting a flat default, and manually adjusting handles to boost high-end crispness, roll off low-end rumble, and reduce nasality.

Step-by-step

Double-click the audio track to select it
Go to the Effect menu and select EQ and filters > Filter Curve EQ
Go to Presets and settings > Factory presets > Defaults to start with a flat line
Grab the high-end handle and boost it up to 6dB for clarity
Click above 100Hz and add another dot at 60Hz to roll off the low-end rumble
Add dots around 200Hz and apply a slight boost for warmth and presence
Select the mid-range handles and fade them down to reduce nasality
Click Apply

Options

Adjust the zoom level to work within a specific decibel range

Tips

Avoid huge boosts; aim for a maximum of 6dB
Roll off frequencies below 60Hz to remove mic pops and low-end rumble that isn't audible in the voice
Boost around 200Hz to add warmth to the recording
Reduce the mid-range if the recording sounds too nasal
