Some old German HiFi equipment had a valume knob that used "Gehörrichtige Lautstärkeregelung". https://www.radiomuseum.org/forumdata/upload/Grundig%5FRTV1020%5FLoudness%5FInfo%2EPNG https://www.radiomuseum.org/forumdata/upload/Grundig%5FRTV1020%5FLoudness%5FKurven%2Epng very nice, I don't...

Do I right understand that you need an Equalizer which will have different equalization (according to the loudness curve) depending on the gain settings? Some old German HiFi equipment had a valume knob that used "Gehörrichtige Lautstärkeregelung". https://www.radiomuseum.org/forumdata/up...

yea, the EQ/convolver needs a diferent curve every 5dB or so. It needs a proper volume control which will change the curves when changed. an EQ/convolver software with a switch to change between (6 or so) curves would actualy do the job the dev explains the theory here: https://github.com/dpapavas/...

any dev willing to dev a plugin version of the alsa software?
we can talk about sponsoring

Hi LSP devs,
as you guys seam to be the most active Linux plugin devs, is there any intrest to dev a plugin version of this software?

I would sponsor this or try to crowdfund it (depending on price)

@sadko4u: Just to make sure that it's correct, what I'm doing: When saving the filter.req file from REW I have to choose the GENERIC filter type, right? When importing this into your EQ it automatically jumps to APO. In here I have to choose PK, I guess (as written a page above from here): https://...

Thanks! I thought it's not implemented yet. Wow... the difference between e.g. APO and RLC is quite huge. Is it because of different Q definitions? why not use one of the LSP convolvers? How will this work and is there any advantage? there is in option in REW to export the filter IR. it then can be...

found out it changes with samplerate. 88.2 is minimum to get flat to 20Khz

Though I had heard about the human ear's "Fletcher-Munson" sensitivity thing some years ago, I had forgotten all about it. ...at last I realize what exactly that "loudness" button on my amp in the 80s was for :D I'd be quite interested in software tools which address the subject...

Has anybody ever directly looped-back alsa-out to alsa-in in a alsa-jack-loopback and measured the response in REW?

I measure a HF-roll-off after 16Khz:

Is it ok to choose the Generic EQ in REW? Yes And which slope factor to use in the LSP EQ then and what type of EQ (resonance?)? Settings: I set up the first equalizer in the LSP parametric EQ as in your settings as an example. See below. The slope control does not affect the APO style of filter. h...

our 40+ members might remember those loudness buttons on recievers and amps of the 70ies and early 80ies. They ideia behind it (though poorly realized back then) actualy makes a lot of sense: https://en.wikipedia.org/wiki/Equal-loudness_contour We all know that to hear the soud balanced you have to ...

I worked weeks on "room correcting" and frequency extending the WDR CR7 IRs. And yes, it is much "dryer" now. I think it sounds very good (the clipping ocured at ACC encoding stage. wont redo it for this simple demonstration): https://www.youtube.com/watch?v=3PrRXjyarpg https://w...
