I think it would anyway make sense to make one or more LADSPA plugins out of the equalizer code (I say one or more, because of the lack of parametrization support in LADSPA). That way the equalizer would be available also to other software than just PulseAudio (I'm thinking PipeWire in particular). If a suitable LADSPA plugin existed, we might or might not still need a separate equalizer module, but in any case we wouldn't need to maintain the DSP code in PulseAudio. If there's some reason why module-ladspa- sink isn't (and can't become) suitable for implementing the integration in PulseAudio, then a specialized module is fine. I'm not saying that I'm dead against hosting the DSP code in PulseAudio, but I'd certainly prefer not to. -- Tanu https://www.patreon.com/tanuk https://liberapay.com/tanuk _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
