Filter effects
MainStage Filter effects overview
Filters are used to emphasize or suppress frequencies in an audio signal, resulting in a
change in the tonal color of the audio.
MainStage contains a variety of advanced filter-based effects that you can use to
creatively modify your audio. These effects are most often used to radically alter the
frequency spectrum of a sound or mix. Several filter effects provide a Side Chain input.
Included are AutoFilter and Spectral Gate which can be used for interesting sound design
manipulations, the vocoder-based EVOC20 Filterbank and EVOC20 TrackOscillator plug-
ins, and the Fuzz-Wah.
Note: Equalizers (EQs) are special types of filters. They are not usually used as “effects”
per se, but as tools to refine the frequency spectrum of a sound or mix. See MainStage
Equalizers overview.
AutoFilter
MainStage AutoFilter overview
AutoFilter is a versatile filter effect with several unique features. You can use it to create
classic, analog-style synthesizer effects, or as a tool for creative sound design.
The effect works by analyzing incoming signal levels through use of a threshold parameter.
Any signal level that exceeds the threshold is used as a trigger for a synthesizer-style
ADSR envelope or an LFO (low frequency oscillator). These control sources are used to
dynamically modulate the filter cutoff.
