#X text 25 57 [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 cycles per second and can take a signal or float - if a float is given as in the example below \, a slightly faster algorithm is used., f 74;
