Deep Noise Remover on Fedora: crashes and performance

[mavit]

I tried following the FAQ entry Why is the Deep Noise Remover effect showing as not available/not installed for me on Fedora? for the EasyEffects RPM, but received a SIGABRT.

So, instead, I made my own build.

However, it appears that my hardware is not fast enough to run this filter in real-time. Could someone who already has this working give my build a try, so we can see if it is indeed my hardware that's the problem, or if something's wrong with the build?

As an Arch Linux user I can't help you with this. But my suggestion would be to do some tests with the Flatpak package. If its build of the deep noise remover runs fast enough on your computer then your custom build has problems.

That being said this plugin does use a lot of cpu power. It is totally possible you cpu is not able to handle it. Something that may help a bit is forcing pipewire to use high latency. The lower the latency is the more cpu is used. Run pw-top and take a look at the quantum column value in your soundcard or microphone line depending on the case. A quantum of 128 or 256 combined with a heavy plugin like this one requires a powerfull CPU.

The Flathub Flatpak crashes in the same way as the release plugin, but, digging into the logs, this does look like a hardware issue:

thread '<unnamed>' panicked at 'DF 6787491c0adc | Processing too slow! Please upgrade your CPU. Try to decrease 'Max DF processing threshold (dB)'.', ladspa/src/lib.rs:444:17

Decreasing "Max DF processing threshold" to the minimum doesn't help, and the PipeWire quantum in already 1024, so it seems this plugin is a no-go on this CPU.

I will leave the Copr repository around, in case other people find it a more convenient way to install the plugin.
