Crayon Filter is a multi-band filter plug-in. You can engage up to five filter types at once (one of each type).

• Low Pass attenuates high frequencies, giving your sound a "dull" feel.
• Band Pass attenuates both above and below the cutoff frequency, for a "thin" or "nasal" sound.
• High Pass removes low frequency signals.
• Notch removes just a small band of frequencies from the signal.
• Peak boosts a small band of frequencies in your audio.
