- one-pole low pass filter
lop~ is a one-pole low pass filter with a specified rolloff frequency.
The left inlet is the incoming audio signal. The right inlet is the cutoff frequency in Hz.
<-- scroll to change input frequency
<-- reinitialize internal state
<-- set cutoff frequency
The filter is initialized to cut off frequencies above 5 Hz.
env~ gives the amplitude of the signal in dB.
Compare the strength of the original signal on the left with that of the filtered signal on the right.
