Repository of equalization filters

That’s interesting. Oratory1990 has said the results will be the same for headphones. Convolution filters are really for room correction with speakers. I have briefly compared the two in Roon and I could not hear any difference.

I quote from the AutoEq github page:

PulseEffects / EasyEffects is a Linux module with wide variety of signal processing tools including convolution and parametric equalizers.

From version 4.7.2 onwards PulseEffects added support for convolution FIR filters. This is the recommended way to apply AutoEq presets. Navigate to the plugins tab and add the convolver plugin, then click the waveform button above the stereo width controls (or just the ‘Impulses’ button as of 6.1.x), click “Import impulse” and select the AutoEq generated WAV file. You may also need to manually click ‘load’ in the Impulses menu for the filter to be fully loaded. PulseEffects’ convolver requires you to set the input gain to prevent clipping. The gain required by parametric eq should be sufficient, maybe 0.5 dB of negative gain more. Depending on the version, you may need to rename the .wav file as .irs.

To use parametric eq, from version 6.0.0 onwards, first select the plugins tab at the bottom of the screen, add the equalizer plugin, and load APO settings by clicking “Load APO Preset” and selecting the ParametricEQ.txt file. For EasyEffects <= 6.1.3, Pre-amp can be adjusted with the input slider. Later versions support reading this from ParametricEQ.txt.

From version 5.0.0 onwards, PulseEffects was renamed to EasyEffects and uses PipeWire instead of PulseAudio as backend. Load eq settings by clicking the top center cog & clicking Import ACO Presets button and select the ParametricEQ.txt file. Pre-amp can be adjusted with the input slider.
