Hello,
I'm new to all of this.
I'm trying to make FIR convolution on a Raspberry Pi 2.
I have succeeded in making Jack2 working (Playback only, no full duplex).
My alsa player can connect to Jack2 and jack2 to the hw I2S sound card,
Fine.
Now, this is what I'm trying to acheive :
Start Jack2 (with jconvolver as input and I2S soundcard as output)
Start jconvolver and Connect it to Jack2
Start Alsaplayer and Connect it to jconvolver as the audio input
Here is my asound.conf
/# convert alsa API to jack API
# use it with:
# % aplay foo.wav
# pcm type jack
pcm.rawjack {
type jack
playback_ports {
0 system:jconv_1
1 system:jconv_2
}
capture_ports {
0 system:capture_1
1 system:capture_2
}
}
# jackplug
pcm.jack {
type plug
slave { pcm "rawjack" }
hint {
description "JACK Audio Connection Kit"
}
}
# use following peripherical by defaut with alsa:
pcm.!default {
type plug
slave { pcm "rawjack" }
}/
Here is my jconvolver config file: jconvolver filter-44100.conf
/# Replace by whatever required...
#
/cd /root/folve/filter
#
#
# in out partition maxsize density
# --------------------------------------------------------

/impulse/read 2 2 0.75 0 0 0 1

/
When I start jconvolver, I get the following error :
*Can't initialise convolution engine.*
Thank you all for any tweak,
Jean

When I start jconvolver, I get the following error :
*Can't initialise convolution engine.*
you need to use unique input names i guess (both seem to be called
"jconvolver"). since they will be prefixed by the client name anyways,
"in_L", "in_R", "out_L" and "out_R" are probably a
good choice...

You probably need to connect everything...
jack_lsp -p to see a list of all jack ports.
jack_connect to make connections.
The connections from jconvolver to the sound card can be
made automatically: just add them to the /input/name
lines in the config file.

You are right, I just understood there was something missing !
I'm sorry as I'm really new to all these stuffs.
So here is my procedure :
1/ start jack2 : jackd -d alsa -r 44100 -p 256 -n 16 -P -S */exact ?/*
2/ start jconvolver : jconvolver filter-44100.conf
*3/ Conect jconvolver to soundcard : ???*
4/ start squeezelite
Thank you for your help

2/ start jconvolver : jconvolver filter-44100.conf
3/ Start squeezelite : squeezelite-arm -o jack
I get sound, and it is convoluted
However, now I would like to know if all this could be done without jack ?
I have the feeling the sound is not as good as what I got from BruteFIR or
from Folve
I don't want to use none of these as they both have their drawbacks.
Any idea os suggestion to make my setup better ?
Thank you and best regards,

I don't think it is...
Sorry, I made a mistake: you need to connect the *outputs*
of jconvolver to the soundcard, i.e. add the soundcard
ports to the /output/name lines.
3/ Start squeezelite : squeezelite-arm -o jack
This will probably connect directly to the soundcard,
not to jconvolver. So you get sound, but without the
convolution.
What you can do is:
Add the connections from squeezelite to jconvolver to
the config file (on the /input/name lines). Then
- start squeezelite,
- disconnect it from the soundcard using jack_disconnect
with the correct port names,
- start jconvolver, this will make all connections.
This assumes that squeezelite does not need to be
restarted for each track.

You are right
I first thought you made a mistake and had tried to connect the *outputs* of
jconvolver to the soundcard, i.e. add the soundcard ports to the
/output/name lines.
But didn't got sound.
than Idid what you said connect the *intputs* of jconvolver to the
soundcard, i.e. add the soundcard ports to the /intput/name lines.
and got sound, but after listening to a known track, I understood that it
was not convoluted.
So what i just did, and now it looks like working.
I changed again filter-44100.conf, this way :
/# Replace by whatever required...
#
#/cd /root/folve/filter
#
# in out partition maxsize
# ---------------------------------------------------------------
/convolver/new 2 2 1024 65536
#
#
# num port name connect to
# -----------------------------------------------
/input/name 1 in.L

/impulse/read 2 2 0.75 0 0 0 1 T-Monacor_SPH30X.wav
#/
Than,
1/ start jack2 : jackd -d alsa -r 44100 -p 256 -n 16 -P -S
2/ start jconvolver : jconvolver filter-44100.conf
3/ jack_disconnect system:playback_1 jconvolver:out.L -> OK
4/ jack_disconnect system:playback_2 jconvolver:out.R -> cannot disconnect
client, already disconnected?
5/ start squeezelite : squeezelite-arm -o jack
I have sound and quite sure it is convoluted,
i'm a little bit lost in all this !
What do you think ?
Best regards and thank you for helping me.

Hello ,
Another problem !
Unfortunately, Jack server crashes after a while !
/JackAudioDriver::ProcessGraphAsyncMaster: Process error
JackEngine::XRun: client = jconvolver was not finished, state = Triggered
JackEngine::XRun: client = rawjack was not finished, state = Triggered
JackAudioDriver::ProcessGraphAsyncMaster: Process error
JackGraphManager::Disconnect not connected port_src = 6 port_dst = 2/
It looks like a xrun problem, I have seen that it happens, whith the
Raspberry Pi and maybe to prevent it
instead of : jackd -d alsa -d hw:sndrpihifiberry -r 44100 -p 256 -n 16 -P -S
One should use : jackd -d alsa -d hw:sndrpihifiberry -r 44100 -p 16 -n 16 -P
-S
But this doesn't work for me as I get an error message when I start
jconvolver :
Fragment size is too small
This can maybe solved, as jconvolver has some tweak for Fragment size built
in.
But, here again, it is beyond my understanding, sorry !
Note, that I used BruteFIR and moved to jconvolver just because of the same
kind of problem, convolution crashes after a while (between 2 and 5 hours of
running).
What can I do, if anything can be done ?
Best regards,
Jean

Did you try using JACK with a number of periods of 2? 16 is quite an
uncommon value. And you're also using -S, never had to use that on my
Raspberry Pi's with Wolfson/Cirrus Logic cards. I do have to use -s
(softmode) in order to keep JACK running. Also try raising the latency,
so use something like a period value of 1024:
jackd -d alsa -d hw:sndrpihifiberry -r 44100 -p 1024 -n 2 -P -s

Thank you, Jeremy, for your answer.
I just tried what you proposed, it is running, let's see if it works for a
few hours, I hope so

Completely off-topic, but since I made the same mistake (to the general
merriment of the native speakers present): the verb form you are looking
for is *convolved*, meaning "has been through a convolution process".
The adjective *convoluted* means something is overly complex or
difficult to follow. Now evil minds might say "precisely", but I guess
once you've dug into this a bit more you will find jack and jconvolver
to be very friendly and reliable tools, and not at all convoluted.
Best,
Jörn

Because squeezelight was not connected.

Please think for a second. It doesn't make any sense to connect
an input to an input.
You always need
jack_connect some_output some_input
For example
jack_connect jconvolver:out.L system:playback_1
jack_connect jconvolver:out.R system:playback_2
Note that the system:playback ports are *inputs*, even
if they correspond to the outputs of the sound card.
Think of these ports as the inputs of the D/A converters.

This is OK.
1/ start jack2 : jackd -d alsa -r 44100 -p 256 -n 16
-P -S
Try -p 256 -n 2, or -p 512 -n 2. There is no reason to use
16 periods, or shorter periods.
2/ start jconvolver : jconvolver filter-44100.conf
OK.
3/ jack_disconnect system:playback_1 jconvolver:out.L
-> OK
Can't be OK, this is input -> output, and it should be the reverse.
4/ jack_disconnect system:playback_2 jconvolver:out.R
-> cannot disconnect
Same.
Try this:
1. Start jack (with -p 256 -n 2).
2. Start squeezelight.
3. Use jack_lsp -c to see the ports and the connections.
Probably squeezelight has connected to the playback ports,
and you have sound. If that is the case, use jack_disconnect
to disconnect squeezelight (2x). Verify again with jack_lsp -c.
There must be no connections.
4. Start jconvolver.
5. Use jack_connect to connect squeezelight to jconvolver:in (2x).
6. Use jack_connect to connect jconvolver:out to the soundcard (2x).
If all of this works, you can put the connections in the
jconvolver config file. Then if you start jconvolver last
it will make all the required connections.
*** But then you still need to remove the direct connections

Hello Fons,
I understand that I'm a little bit boring, but should I have a gui, it would
have been more easy to understand.
But I'm working headless, so only CLI.
For you all this is obvious, for me, like a blind, it is not.
Anyway I thank you for your efforts, and I think I will finish to make it
right.
Starting jack, then, Squeezelite doesn't work at all.
But I caught what you said from the begining in jconvolver config.
So here is my config

So now the procedure is :
1/ Start Jack : jackd -d alsa -d -r 44100 -p 256 -n 2 -P -s
2/ Start jconvolver
3/ Start Squeezelite
I get sound.
And here is the result of jack_lsp -c
/system:playback_1
jconvolver:out.L -> OK, I guess
system:playback_2
jconvolver:out.R -> OK, I presume
jconvolver:in.L
rawjack:out_000 -> OK,
jconvolver:in.R
rawjack:out_001 -> OK,
jconvolver:out.L
system:playback_1 -> ???
jconvolver:out.R
system:playback_2 -> ???
rawjack:out_000
jconvolver:in.L -> ???
rawjack:out_001
jconvolver:in.R -> ???

Than, as There is a kind of mystery,
I tried the other way :
Stop Squeezelite, jconvolver, Jack
changed back my jonvolver config
# Replace by whatever required...

1/ Start Jack : jackd -d alsa -d -r 44100 -p 256 -n 2 -P -s
check connections : none -> OK
root@DietPi:~/folve/filter# jack_lsp -c

2/ tried to start squeezelite >-error
/cannot connect rawjack:out_000 to jconvolver:in.L
cannot connect rawjack:out_000 to jconvolver:in.L
cannot connect rawjack:out_000 to jconvolver:in.L
cannot connect rawjack:out_000 to jconvolver:in.L/
etc...
Stop
3/ Start jconvolver
check connections -> STRANGE !
system:playback_1
jconvolver:out.L
jconvolver:out.R
system:playback_2
jconvolver:in.L
jconvolver:in.R
jconvolver:out.L
system:playback_1
jconvolver:out.R
system:playback_1
so, I did
/jack_disconnect jconvolver:out.L system:playback_1
jack_disconnect jconvolver:out.R system:playback_1/
check again
/system:playback_1
system:playback_2
jconvolver:in.L
jconvolver:in.R
jconvolver:out.L
jconvolver:out.R/
than try to Connect corectly
/root@DietPi:~/folve/filter# jack_connect jconvolver:out.L system:playback_1
root@DietPi:~/folve/filter# jack_connect jconvolver:out.R system:playback_2
root@DietPi:~/folve/filter# jack_lsp -c
system:playback_1
jconvolver:out.L
system:playback_2
jconvolver:out.R
jconvolver:in.L
jconvolver:in.R
jconvolver:out.L
system:playback_1
jconvolver:out.R
system:playback_2
/
4/ Start Squeezelite
and check connections once again :
/root@DietPi:~/folve/filter# jack_lsp -c
system:playback_1
jconvolver:out.L
system:playback_2
jconvolver:out.R
jconvolver:in.L
rawjack:out_000
jconvolver:in.R
rawjack:out_001
jconvolver:out.L
system:playback_1
jconvolver:out.R
system:playback_2
rawjack:out_000
jconvolver:in.L
rawjack:out_001
jconvolver:in.R/
I get exactly what I got here above.
Should I conclude It is right, although strange, at least to me... ?
Thank you again and Best regards,
Jean

Hello,
Doesn't my connections problems originate from my asound.conf
For recall, here is my config files :
asound.conf :
/# convert alsa API to jack API
# use it with:
# % aplay foo.wav
# pcm type jack
pcm.rawjack {
type jack
*playback_ports {
0 jconvolver:in.L
1 jconvolver:in.R*
}
capture_ports {
0 system:Output_L
1 system:Output_R
}
}
# jackplug
pcm.jack {
type plug
slave { pcm "rawjack" }
hint {
description "JACK Audio Connection Kit"
}
}
# use following peripherical by defaut with alsa:
pcm.!default {
type plug
slave { pcm "rawjack" }
}/
At east this explain why squeezelite doesn't connect if jconvolver isn't
active
So I tried to come back to the ealier version of asound.conf where
squeezelite connect directly to jack.
Than,
I start Jack,
I start Squeezelite
/root@DietPi:~/folve/filter# jack_lsp -c
system:playback_1
rawjack:out_000
system:playback_2
rawjack:out_001
rawjack:out_000
system:playback_1
rawjack:out_001
system:playback_2/
I can disconnect
/root@DietPi:~/folve/filter# jack_disconnect system:playback_1
rawjack:out_000
root@DietPi:~/folve/filter# jack_disconnect system:playback_2
rawjack:out_001
root@DietPi:~/folve/filter# jack_lsp -c
system:playback_1
system:playback_2
rawjack:out_000
rawjack:out_001/
start jconvolver
/root@DietPi:~# jack_lsp -c
system:playback_1
jconvolver:out.L
jconvolver:out.R
system:playback_2
rawjack:out_000
rawjack:out_001
jconvolver:in.L
jconvolver:in.R
jconvolver:out.L
system:playback_1
jconvolver:out.R
system:playback_1/
It didn't work, I should again disconnect and reconnect to make it work
So I conclude that my latest setup was the good one
Right ?
Best Regards,
Jean

Sorry, I made a mistake in my latest post as the jconvolver config was not
set !
It explains why I had bad connections.
So once more
I start Jack,
I start Squeezelite
I get sound obviously non convolved
/root@DietPi:~# jack_lsp -c
system:playback_1
rawjack:out_000
system:playback_2
rawjack:out_001
rawjack:out_000
system:playback_1
rawjack:out_001
system:playback_2/
I make the disconnections
/root@DietPi:~# jack_disconnect system:playback_1 rawjack:out_000
root@DietPi:~# jack_disconnect system:playback_2 rawjack:out_001
root@DietPi:~# jack_lsp -c
system:playback_1
system:playback_2
rawjack:out_000
rawjack:out_001
/
I start jconvolver
And I get sound again, obvioulsy convolved
root@DietPi:~# jack_lsp -c
system:playback_1
jconvolver:out.L
system:playback_2
jconvolver:out.R
rawjack:out_000
jconvolver:in.L
rawjack:out_001
jconvolver:in.R
jconvolver:in.L
rawjack:out_000
jconvolver:in.R
rawjack:out_001
jconvolver:out.L
system:playback_1
jconvolver:out.R
system:playback_2
Fons, is this setup OK ?
From my side, I like this way as I can directly compare
the convolution
effect.
Best regards,
Jean

For you all this is obvious, for me, like a blind, it is not.
Anyway I thank you for your efforts, and I think I will finish to make it
right.
Could you PLEASE try to post only correct information.
In this message you write things that to me look impossible.
I have to guess all the time which error you made when writing
your message. This doesn't work !!!!

This looks OK.
So now the procedure is :
1/ Start Jack : jackd -d alsa -d -r 44100 -p 256 -n 2 -P -s
2/ Start jconvolver
3/ Start Squeezelite
I told you to start jconvolver *last*. If you start it before
squeezelight, the rawjack ports don't exist, so the connection
can not be made.
The means that the following can not be correct:
I get sound.
And here is the result of jack_lsp -c
/system:playback_1
jconvolver:out.L -> OK, I guess
system:playback_2
jconvolver:out.R -> OK, I presume
jconvolver:in.L
rawjack:out_000 -> OK,
jconvolver:in.R
rawjack:out_001 -> OK,
jconvolver:out.L
system:playback_1 -> ???
jconvolver:out.R
system:playback_2 -> ???
rawjack:out_000
jconvolver:in.L -> ???
rawjack:out_001
jconvolver:in.R -> ???
There is nothing wrong with the last four, they are
the same as the first four. But these connections
can exist only if you start jconvolver last.
Than, as There is a kind of mystery,
There is no mistery. These are the correct connections.
