# Filter

A Filter is used to amplify (boost), pass or attenuate (cut) defined parts of a frequency spectrum. Easy Effects uses the Filter from Calf Studio Gear.

# Mode

The type of the filter.

# Frequency

The center or cut-off frequency of the filter.

# Resonance

Add an accentuation to the center frequency. When used on a bandpass the surrounding frequencies are decreased in level and the band gets more narrow. A bandreject is narrowed down to a thin needle.

# Inertia

Smooths the jumps between frequencies.
