Fabfilter Pro-Q 3: Identify boomy frequencies with a high-pass filter

Demo summary

The creator demonstrates how to use a high-pass filter on an EQ to sweep through low frequencies and isolate the specific range (100-300 Hz) causing boominess.

Step-by-step

  1. Open the EQ plugin
  2. Solo the vocal track
  3. Enable a high-pass filter
  4. Slowly sweep the filter frequency upward while listening for the boominess to disappear

Tips

  • Use a high-pass filter to identify problematic frequencies instead of sweeping with a standard band
  • Look specifically in the 100 to 300 Hz range as this is where boominess typically resides
