MovAvg Description

The MovAvg SynthEdit module was developed to be a moving average filter. Calculates average of last n input samples. Technically it is a FIR (finite impulse response) filter with a rectangular kernel. Soundwise it is like a comb filter plus a 6 dB/octave lowpass filter.ParametersThe frequency / width can be controlled by the Freq / Width parameter.Input modes:1 Volt/kHz - calculate frequency using 1 V/kHz scale 1 Volt/Octave - calculate frequency using 1 V/Octave scale 1 Volt/ms - Freq/Width determines the length of the window in millisecs TimeCent - the length of the window is 2^(volts-6.6666666) seconds OptionsThe 'Max length (secs)' option determines the maximum window width. It is suggested to set this to the minimum necessary. The relationship between the minimum possible cutoff frequency and the maximum length is:fmin = 0.883/(2*t) So, for the default 0.1s maxmimum length, the minimum cutoff frequency is 4.4 Hz. The Maximum length option is limited to 10 seconds.Possible usesSmoothing control signals, portamento effects, signal level detection, etc. Not designed for fast modulation.
