Loading IR seems to create DC issues.

[38github]

I compiled the up to date code and it loads NAM files correctly. However when I add IR in the third slot (haven't tried the fourth) my channel in REAPER auto mutes and when I try to unmute it I hear the low frequency thump that I associate with DC issues. I have tried several IRs but they all do this. When I choose "None" in that slot the issue goes away.

I have compiled it with Clang 18 and _x8664-v3 -O3 -flto -fopenmp -openacc.

Strange, I never experience that. Is that just with the latest checkout or do you get the same with the last release? One thing, when you've done a git pull on a older checkout, run make clean before do a new build. Why did you add those flags? There are some checks in the makefile to setup best matching flags for build, please try a simple make during the build output there is a Info part, that one I'd like to see, here it is

 INFO: optimised for -march=x86-64-v3 -msse3 -mfpmath=sse -mfxsr
 INFO: build with    clang++    
 INFO: using         -std=c++20

by default, Ratatouille is build with -Ofast, not with -O3

Did just a quick test in Reaper, I can't reproduce the issue here.

It was a clean git clone. With the 0.7 release tar ball I can't load an impulse response. When I have opened the file it does not display in the plugin.

please try a simple make

 =================== DONE =======================

Same thing happened with the new build without any added flags.

The volume is ramping up after a second and causes the channel to auto mute.

Could you give me some more info, Your Session Sample Rate: your buffer size settings: Sample Rate of the IR File: size of the Ir File (samples or ms): is it a stereo IR File: Do you enabled oversampling in Reaper: happen the issue with any other host, ardour, carla, qtractor, . . . :

Still I can't reproduce the issue, but, I tempted to push a fix for it. Please let me know if the last commit fix the issue for you.
