Hi.
Tomorrow Tuesday it's again the Linux audio meeting at c-base in
Berlin. See you there at 20.
Cheers

Hey everyone!
I am not able to make it this time, have competing plans. Hope you guys
have fun!
Some suggested topics for you:
- What did you think about presentations at Sonoj
<https://sonoj.org/schedule.html>? Specifically unfa's presentation of a
new synth was interesting (Vital)
- The state of sound engineering tools on Linux Audio: EQs, compressors and
limiters. What is the actual DSP level of these, compared to commercial
counterparts.
Louigi.

New synth? Didn't know about that.

"actual DSP level"?
I on the other hand was wondering if there's a Linux VST for
convolution reverb so we could test out the Teufelsberg impulse
responses in the soundlab:

I meant DSP quality.

It would be interesting, if this is actually discussed, if outcomes
could be shared on LAU ML. In particular also what the metrics for
assessment/comparison were/are

What DSP quality means would depend on the function discussed. EQuing and
compressing each have their own DSP challenges.
In around 2010 a sound engineer that helped me a little bit with my album
<https://louigiverona.com/?page=projects&s=music&t=another_reality>
assessed the Linux EQ plugins and found most of them to be unusable due to
them generating noisy artifacts. He did single out a couple of plugins
which seemed to do the job well. If I remember correctly, it was this one
<http://eq10q.sourceforge.net/>. Unfortunately, I have noticed this myself
when producing ambient. Using Zyn EQ, for example, would generate a light
hiss that I had to later clean out after render.
But obviously, experts should look into this, and I think this conversation
could be useful.

Sure. I'm just saying that I don't understand what "DSP quality" means
or how to measure it in this context...

I guess Robin can weigh in on this.

This would be an interesting subject for testing and discussion.
I use the EQ10Q plugins you linked and they seem to work well,
particularly the EQs and gate. X42 plugins work nicely along with most
of the Harrison ones. AVLinux includes hundreds of plugins and it's
impossible to try them all although I've been pleasantly surprised by
some previously unknown ones such as TAL and Dragonfly reverbs.
Some other plugins I've tried and abandoned quickly because they just
sound bad. Hard to tell whether that's bad DSP or just unwieldy controls
that that make it difficult to achieve the desired result.
Some actual scientifically valid testing would be illuminating rather
than just perception of quality as a user.
Cheers, Roger
