"...how can I use the FIR filter in the Freeverb3 open
source library..."
Freeverb3 is not a library by nature, I think but anyhow, it might be
GPLd (Gnu Public Licence) which puts some restraints on how you can use
the code, in some cases you´ll have to publish the source of your
derived work
Robert and Nigel,
many thanks for your valuable input, I'll investigate more on that direction
then (DFT + iDFT).
Regards,
Charles

Off the top of my head: You'd probably need a relatively long FIR, as the
filter moves down (to maintain a good dB/oct rolloff), though you could take

I see your point but I was thinking of a synth where the single-cycle waveform
are actually predefined
Without being quite sure how you intend to
use the filter I don't know if this advice is useful;
But for wavetable synthesis you don't really need
a filter, as such.
For preparation of tables it is usual to do it
by construction, to build the table additively
from a sum of partials. That way y
Dear Members,
I'm trying to figure out how can I use the FIR filter in the Freeverb3 open
source library as an anti-aliasing filter in a wavetable synth.
More in detail: I'd like to use it in the initialization phase to pre-
calculate a lookup table of filtered waveforms starting from single-cyc
