       TIL about Easy Effects which allows to easily apply various filters (EQ, compressor...) to the audio output (or even input) using #PipeWire on #Linux: https://github.com/wwmm/easyeffects 🎉I use a Focusrite 18i20 audio interface, with 2 sets of speakers: either the main monitors on my desk, or a Bose Soundlink Mini sitting on top of my guitar amplifier.Switching between the monitors and the Bose is as easy as pressing the "ALT" switch on the 18i20, but then I had a tiny problem...1/#LinuxAudio

       The Bose is used mainly when playing the guitar, either for playing along a tune, or for listening to the click track without having to put headphones on.Of course, this requires that the volume is set quite high in order to hear it without being completely drowned in the guitar sound.The problem is, as this speaker has a rather prominent low-end, the sound at a high volume is excessively boomy, and I don't want my whole building to collapse, right?2/

       At first I considered buying a rack-mount graphic EQ (e.g. Behringer Ultragraph) so I could EQ the signal sent to the Bose without affecting the main monitors. However, do I really need a full-featured EQ just for cutting some low-end? No, not really...My next idea was building myself a DIY stereo low-cut filter with a bunch of capacitors and a rotary switch, but that would've required buying a few parts I was missing, as well as an additional cable or 2... And I'm in "lazy mode" this week3/

       With Easy Effects I could quickly dial in an EQ curve that would tame the low-end just the right amount so the Bose would still sound lively, without getting any of the problematic rumble...Now this also affected my main monitors, so I'd need to open Easy Effects any time I'd switch speakers and manually enable/disable the EQ. But then, I'm a nerd, that's also a problem I can solve 😉The "ALT" button is reported as an ALSA control named "Speaker Switching", which will come in handy!4/
