Maybe your buffer size is not power of 2? Could you try the last guitarix version from master, there should be some fixes implemented?

psilhavy commented 6 months ago

Which buffer ? How to check it (gdb/lldb) ? Only visible buffer is audio output which is set to 256.

Yea, I mean the audio buffer size. 256 is suitable. I would suggest to try guitarix from master branch and build it with the --includeconvoler flag. As I said, some issues with the convolver been fixed in latest master.

This seems not to be the latest master version from github as this is fixed since Jan. 31. 2023 see here: https://github.com/brummer10/guitarix/blob/master/trunk/src/LV2/DSP/gx_common.h#L25

Try this to get the latest:

git clone --recursive https://github.com/brummer10/guitarix.git
cd guitarix/trunk
./waf configure --includeconvolver --no-avahi --lv2dir=/usr/local/lib64/lv2 --libdir=/usr/local/lib64
sudo ./waf install

you may deinstall guitarix from your distribution before install guitarix from git to avoid symbol clashing!!

psilhavy commented 6 months ago

Works fine! Thank you for your cooperation and patience.

BTW maybe the message officially mirror of https://sourceforge.net/p/guitarix/git/ci/master/tree/ on your github is misleading for other people too.
