Hi all,
recently there was a discussion about the different ways of avoiding
aliasing. One of these is oversampling, but as far as i know there is only
one example of it in Pd help patches, and it has a phasor in the subpatch. I
m assuming that i could use the Butterworth filter in the subpatch
The frequency components introduced by aliasing cannot be removed (at
least not by low-pass filtering) once introduced, and this happens at
the level of signal generation, not at the interface to the dac. Since
it is the phasor which is actually aliasing, it needs to be antialiased
with a low
Sorry, the only solutions I've ever known is to antialias the signal
sources by low-pass filtering them before they reach a sampling rate
where they could alias, or by using band-limited signal sources in some
way or another. Once the aliased frequencies are in, it's pretty near
impossible to
The simple but expensive answer: just oversample your entire
patch!!! ;-)

dear derek, dear list
is there any possiblity to make an antialaising for the dac output of a
mixed signal?
thanks in advance
