What is the effect of calling lag() on a frequency parameter?

hey,

Lag is a OnePole filter, which takes the current value of the input signal and adds it to the prior output value. Often times filter coefficients are calculated in cycles per seconds (hz) for a filter cutoff but they can also be calculated in time (sec) to smooth out control signals.

Onepole filter for dummies

In digital signal processing time is passing by in samples. The number of samples which are passing by in seconds are specified by the sampling rate (for example 44100 or 48000). For a filter we want to evaluate a function for every sample, which has an input and an output. The specific function we want to evaluate per sample for a OnePole filter takes the current value of the input signal and adds it to the prior output value. So we need to remember the value of the last output sample. To rem…
