The antialiasing filter shown above is taken from the example J07.oversampling.pd in the 03.audio.examples folder found in the Pd Documentation Browser in the application. Because this is a very CPU intensive process, it is wise to only include the oscillators you wish to antialias in this subpatch, and to control them via the [inlet]s of the ...

Using the same audio example, if we want to keep the sampling rate at 44.1 kHz, the anti-aliasing filter will need to have an attenuation of 40 dB at about 22 kHz. With a bandwidth of 20 kHz, the filter will need a transition from 3 dB at down to 40 dB within 2 kHz.
