Re: [Alsa-user] How do I set up a filter/plugin?

Hi Ralf

This is nice to know, thanks. I thought perhaps that LADSPA plugins
only required ALSA to work?

And yes pipewire is still a work in progress, however I haven't found
bugs or encountered weird
behavior yet. I have it installed as a telegram-desktop dependency on
Arch Linux, so I might as well
install pipewire-jack, which is a drop-in replacement for standalone
jack. I found out pw-play works
nicely (like aplay), I haven't tried pw-record yet.

Thank you

Hi,

you need a jack compatible host application to load audio plugins such
as LADSPA or LV2 plugins, jack by itself can't integrate plugins.
However, Ardour for example can be used with jack or plain ALSA and
it's also a host for LADSPA and LV2. Pipewire seems not to be without
issues and probably not ready for a reliable recording environment yet.

Ralf

Kevin,
   I don't know how to do that anymore, if I ever did. I've used Jack for
years. In general it works for me but it is a bit finicky.

   As I say, software plugins in a real-time data path aren't something I
ever do anymore. If I really think I need a compressor when recording it's
going to be hardware which has its limitations as per that specific
hardware device. However careful recording with good levels shouldn't ever
be a noise floor issue so I just record softer and boost as necessary. I
use Mixbus, the for-pay version of Ardour. I have general workflow
templates that make getting set up easy, and frankly I'm recording so
seldomly anymore that I'm not even current with much of Linux audio
anymore. The alsa-users list used to be a very lively list. Today it's
terribly quiet. Probably everyone who could help you is either off in a
forum somewhere or winding down like me in retirement.

   Not sure any of this helps but as I say this list is so quiet I wasn't
sure you'd get any answers.

Good luck,
Mark

Thank you for your kind reply, Mark.
The suggestions you gave me are surely helpful, and I will study in
deep some of the things you mentioned.
I agree with you that applying a compressor as part of post-production
would be the most efficient way of having the audio recorded the way I
want.
I am looking at jack too, i'll eventually install pipewire-jack as I
am already running on pipewire, I'll look up for jack-compatible
plugins.
I'd still like to try implementing this with plain ALSA though, just
to learn and experiment with it.
Let me know if you know how to do it this way too!

In time critical applications like recording vocals you may find the
latency through software plugins to simply be unacceptable as it can really
throw off your sense of timing. Most important when recording is to not
have the technology get in the way of the performance.

Should you really want to try it live then I would go with Jack and simply
route the scarlett's output, once inside the machine, through whatever
compressor you want to try and push the Alsa buffer size down as far as you
can without creating xruns.

In my experience though, especially when beginning, I think you're better
off recording the vocal raw and then applying the compressor after the fact
in DAW.

A lot of this depends on your monitoring chain. I Generally find that an
uncompressed vocal sent through a cheap hardware reverb in the monitor
chain is a great way to approach the problem of getting a good dry vocal on
disk. Once the vocal is on disk you can compress it anyway you want. At
that point it's just numbers.

HTH,
Mark
