Descript's high-pass filter (also known as a "low-cut" filter) allows you to trim out lower-frequency audio from your media clips. This is especially useful in situations where electrical "hum" or wind noise may have gotten onto a recording.
Getting Started
If you haven't yet already, check out our Effects Overview for details on adding / removing effects, as well as a breakdown of the various stages you can insert effects into your Composition.
Effect Overview
Unlike a Low Shelf EQ which equally raises / lowers any frequencies below a specified value by the amount you specify, the High-Pass Filter gradually "rolls-off" (removes) any frequencies below the specified value.
Presets
The High-pass filter comes with an array of starter presets to choose from:
- De-Boom Light
- De-Boom Medium
- De-Boom Heavy
- Vocal Limit - Bass
- Vocal Limit - Baritone
- Vocal Limit - Contralto
- Vocal Limit - Soprano
To choose a preset click the "Select Preset" dropdown selector:
Manually Adjusting Effects Settings
You can also manually adjust your settings by clicking on the Show Details button to the right of the preset selector:
Here you can adjust the "Frequency" knob to the left / right to set at which point the roll-off will begin.
