Fabfilter Pro-Q 3: Comparing shelf and notch filters in Pro-Q 3 and 4
Fabfilter Pro-Q 3
Demo summary
The demonstration continues by applying low shelves at 120Hz, bell filters, and high-frequency notches to both plugins to verify they still null perfectly under different filter types.
Step-by-step
- Apply a low shelf filter at 120Hz with a 5dB boost and a Q of 1
- Switch the filter type to a Bell filter
- Invert the gain to perform a cut
- Apply a high-frequency boost at 20kHz
- Increase the boost to 9dB
- Switch the processing mode to Natural Phase
Options
- Toggle between Low Shelf, Bell, and Notch filter types
- Switch between Zero Latency and Natural Phase modes
Tips
- Use a Notch filter for more complex frequency removal tests
- Verify phase alignment by checking for complete silence (nulling) when comparing two plugin versions
