Hey Robin & Fons,
thanks for the replies.
Robin: I must admit that i didn't know the RPi is capable of OpenGL. I
have the "old" RPi (B Version) but as far as i googled, it could do
OpenGL as well, so i will try to run LV2.
Fons: i found your jmeters before and obviously it is great that they
have correct response. I must admit though, that i am not a big fan of
the analog meter style (probably i am just not used to it) and i didnt
find the digital style jackmeters have, or is it already there but just
not documented?
At the TV station i work at we have the RTW TM7
https://www.rtw.com/de/produkte/audio-monitor/touchmonitor-tm7.html
Robin: I never quite understood advantage of the loudness radar which
the RTW device also feautres vs. a horizontal way of displaying the
programs loudness... i think something like the ebumeter combined with
yass oscilloscope (with an additional timescale) would be perfect to get
a quick overview of the dynamic range...
To both of you thanks for your excellent work, i try to get the
"perfect" layout figured out.
cheers,t.

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?
https://github.com/x42/meters.lv2 (if you have a new RPi with openGL,
debian package: x42-plugins) and https://github.com/jiixyj/libebur128/
