The narrator demonstrates applying a 'low roll-off for speech' using the Filter Curve EQ to remove unnecessary low-frequency noise from a voice recording.
Step-by-step
- Go to Effect
- Select EQ and Filter
- Choose Filter Curve EQ
- Open Factory Presets
- Select Low roll-off for speech
- Adjust the curve so the roll-off starts at 80 Hz
- Click Apply
Options
- Slightly boost frequencies above 4 kHz for brightness
Watch out for
- Be careful when boosting frequencies above 4 kHz
Tips
