Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: puredata Group: v0.42 Status: Open Resolution: None Priority: 5 Private: No Submitted By: Matteo Sisti Sette (sistisette) Assigned to: Nobody/Anonymous (nobody) Summary: bp~ weird behaviour above 1/4 Nyquist frequency
Initial Comment: bp~ doesn't work properly if you try to set its center frequency above 1/4 of the Nyquist frequency, e.g. above 11250 Hz in the case of 44.1kHz sampling frequency.
If you push the center frequency above that value, instead of raising it, it seems that the center frequency and Q don't change while the GAIN of the filter grows.
Note that vcf~ does _not_ suffer from this problem.
