Hi,
After spending time trying to get RoomEqWizard (REW) to use Jack
effectively and simply getting frustrated I'm looking for other tools. (REW
is a nice tool but it doesn't support JACK natively and I tried fooling it
with alsa etc., but I think PulseAudio was getting in the way.)
I ended up using jaaa and japa from Fons Adriensen which work great.
But, I'd like to be able to save the display.
I suppose I could use screen shots for each test and that would be fine.
But, I thought I'd see if anyone knows a Linux tool that can do waterfall
plots, frequency response, etc. Maybe even distortion.
Any recommendations?
Regards,
Mac
Hello List,
i am new to this list so forgive if this has been discussed before - a
quick search of the archives didnt reveal anything relevant.
I am trying to build an audio metering device (stereo only for now),
with the purpose of monitoring my video editing system. Right now this
is based on a RPi running Arch Linux ARM. As the window manager i
decided for i3 tiling WM. The RPi has a 7" 800x480 Touchscreen connected
(to be able to reset EBU R128 measuring Keyboard and Mouse-less). As a
soundcard i am using the Behringer U-Control UCA222, connected to a
Samson C-Control as the audio splitter for speaker monitoring etc.
As the software i am playing with the ebumeter, yass & jaaa from Kokkini
Zita (http://kokkinizita.linuxaudio.org/linuxaudio/). I installed the
jackmeterbridge tools as well.
I am still trying to figure out what software will be useful in "real
life" situation, meaning what is the RPi capable of handling CPU wise
(jaaa pushed it to its limits naturally).
- So i wondering, has anyone done something similar before and can share
his / her experiences?
- Are there other software tools that i have missed that would be worth
looking at?
- Especially screen estate is a problem with a 800x480 pixel screen.
Jass fits barely, ebumeter is super small etc. Is there a way to scale
fixed width tools differently to make a nicer screen layout?
best,
t.
Hey hey everyone,
I need to load a soundfont (SF2) from a script. I've tried with LinuxSampler
and it worked, but I only got sound in the first channel (LinuxSampler:0).
In Fluidsynth I get stereo output, but I haven't found a way to select the
desired patch from the soundfont through the commandline options. Using -f
with stdin shuts Fluidsynth down immediately.
Any idea to solve either problem?

Hey hey everyone,
I'm currently studying for one of my electircal engineering causes, which
deals mainly with state-space representation of linear, time-invariant
systems. But I have still failed to grasp the practical meaning of some of the
values involved.
I thought a practical example might help and I've turned to convolution, since
that is a subject I am slightly familiar with. Could someone perhaps help me
here? A link to such an example or explanatory article in LaTex form could be
sufficient.
I'm sorry to misuse this list for such a question. Thank you for reading!

Hey hey everyone,
I've got problems connecting Midish to Yoshimi. Keyboards with and without
active sensing from the mid 80s to the past year work fine. But when I try to
connect Yoshimi from within Midish, I get no sound. LinuxSampler works though.
The midish procedure
dnew 4 "yoshimi" wo # Add Yoshimi to Midish device list
onew "Yoshimi" {4 0} # name first channel Yoshimi
Create a filter to route all events from my keyboard to Yoshimi.
Typos aren't possible, since it's all done by Midish procedures and has been
tested about 10 times.
Does Yoshimi need any special MIDI input beyond noteon/noteoff perhaps?

Background.
I often use my 'office' machine (64 bit dial core Intel - debian 8) to do
experimental work on audio software as I don't want to take risks with my DAW.
Sometimes I use a KA6, other times the motherboard sound depending on what I
want to check. However, I've got into the habit of leaving the KA6 plugged in
anyway.
Recently I've noticed that if I have jack running through the motherboard
audio, I get exactly 1 Xrun approximately every 11 minutes. This doesn't
happen if the KA6 is not plugged in, nor does it happen if I route jack's audio
through it.
If this was some USB issue I would have expected it to be there when routing
through the KA6 as well.
Any ideas?
As an aside, I can run the KA6 at 1/2 the buffer size of the motherboard audio
and still get no Xruns, when the latter is getting quite croaky.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
Saw something I didn't expect while debugging my production box; in
/proc/asound/cards, an entry named FCA202, which was my Behringer FCA202
firewire interface. Since when does ALSA do Firewire interfaces?
I'm tracking a very intermittent freezup bug of some sort, and thought
perhaps this ALSA driver was interfering with JACK and its Firewire side,
and have blacklisted the driver involved (snd_oxfw) just in case. It will
take a lot of testing to come to an opinion whether or not this eliminated
the problem.
But meanwhile, does this mean that I have the option of using
JACK-->ALSA-->FCA202 as well as JACK-->Firewire-->FCA202?
Anyone know which perhaps I should prefer for high performance at low
latency? I'm running 96KHz and liking it a lot...
In case it helps: kernel 4.1.3 Liquorix, Debian Testing, 64-bit, up to
date.

Hi all,
The Center for Computer Research in Music and Acoustics (CCRMA) at
Stanford University is a multi-disciplinary facility where composers and
researchers work together using computer-based technology both as an
artistic medium and as a research tool
(https://ccrma.stanford.edu/about). We are (still) currently looking for
a great person to help lovingly take care of and feed our servers,
workstations, and multichannel audio setups.
The right person will be working with and helping a diverse community of
interdisciplinary students (ranging from undergrads to DMAs and PhDs,
studying Music, EE, CS, and many other fields), researchers, and faculty
from all over the world. Our computers mostly run GNU/Linux but there
are Macs in the studios and even a couple of Windows machines in the
NeuroMusic lab. We do complex multichannel audio setups in our studios
and for concert diffusion (3D sound in up to 25.8 channels), we maintain
all our own servers and backups, and we package our own software (and
other developers' open source free software) in repositories so that
anyone can install it easily. All this is quite a lot of work and we
need help!
Qualities sought: curious, tenacious, responsible, self-motivated,
tech-savvy, willing to learn, artist- and wizard-compatible, strong team
player who can work independently.
Full details about the job are here:

Hi Guys, Galls. I've put some work on guitar synth on GuitarSynth
(https://github.com/geraldmwangi/guitarsynth-dpf). There is a new
parameter per synth called overlay input. What it does is it multiplies
the synth signal with a scaled version of the input audio. That way the
synth sound is attenuated by the guitar sound, making it more
'guitarish' sounding. I would like to hear your thoughts on it. Remember
when testing to turn up the gain of the synth in question, as well the
input gain on the soundcard/alsamixer.
Work on the polyphonic pitch detection is come to a halt, since I'm
wrapping up my PhD, but don't sigh: I'm still reading into the matter
and have some ideas..
