Hello,
I've been trying to make a filter for a few months now, in order to improve the sound I get from Pipewire, which has improved dramatically since version 1.0.0. Today, I thought I'd finally managed to get a sound I was satisfied with, so I took the filter off to check the quality of the sound I was getting from my own filter, and was astonished to hear the sound. The sound through my own filter was not so much different, and the only difference was that there was no reverbation in my own filter.
So, I went to the doctor for my regular check-up, and while I was waiting to be seen, I suddenly had the idea that
"pipewire was using the plugins I had installed to create my filter".
When I got home and checked the source, as I had suspected, it had been. On the other hand, I also found that pulseaudio does not have this function.
BTW, when I installed the lv2 (lv2-SmartAmp) plugin for guitar sounds, which I had only installed the vst3 plugin for, and played it, the sound quality clearly improved.
What I don't understand is that I have installed plugins to improve the sound of string, wind and percussion instruments, but they are all vst3 plugins, and I have created my own filter using vst3 plugins. But there is no change in the sound without the filter... (_ _?
Anyway, I created my own filter in the following way, and I used synthesize to incorporate filters that improve the sound quality of various instruments, along with filters that enhance the bass, but this seems to be the same as the sound source processing that pipewire does.
synrthesize --> equalize --> 7.1 virtualize --> reveb
So I think it would be good to install the lv2 plugins that matches each sink, but I have installed too many lv2 plugins, so I don't know which plug-in matches other than the guitar.
However, I think it's worth a try, so please give it a go. By the way, when checking the effect of installing plugins, be sure to execute
$ systemctl --user restart pipewire pipewire-pulse wireplumber.
I think that people who like jazz and live performances will be fine with this setup (listening on the same floor as the performers), but I like the hall tone we get when listening in a concert hall or church, so I make and use a reverb filter. If there are any people who want it, I will upload the filter, so please let me know.
1 What sound card do you use? I have an Asus XONAR STX-II with some 1/4" jacks as well as a stby XONAR-AE both of which I like. Unfortunately the stx-II is not made anyome! I use adapter pigtails to preserve the card jacks as I really don't wanna be cought without being able to use this card. 2 I jam using Audacity's paused recording mode, it's the only way I can get to actually hear my guitar (Epiphone LP). I used to use jack but I couldn't get it started at all the other day, so I tried pipewire in Audacity and bingo, it just worked (never did before). 2b I used to use qjackctl to record Rosegarden output but now I can't get qjackctl started, how do YOU record RG if you use it all? 3 For effects I use a Boss gx-100, and that makes it also the audio interface, plugged into card Line-In. What audio interface do YOU use if any? How do you get to hear the guitar? I'd like to jam without having to load Audacity except when I want to record my own track. The way I 'see' it, once I select Line-In or Mic-In in the pulse control panel I should hear the guitar, but I DON'T.
