# Filter

Audio filters can amplify (boost), pass or attenuate (cut) some frequency ranges.

PulseEffects uses the filter from Calf Studio. It can be used to remove defined parts of a frequency spectrum.

# 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.
