I have managed to confuse myself again. Fresh install using 'full_install_venv.sh' v.2.1.1 on RPi3 RPi-OS 64-bit Lite running with Python 3.11.2

Back-end is greeting me with
Bash: 
python camilladsp/gui/main.py
Traceback (most recent call last):
  File "/home/pi/camilladsp/gui/main.py", line 1, in <module>
    from aiohttp import web
ModuleNotFoundError: No module named 'aiohttp'

When running the install script again we get this confirmation
Bash: 
Requirement already satisfied: aiohttp in /home/pi/camilladsp/camillagui_venv/lib/python3.11/site-packages (from -r requirements.txt (line 1)) (3.9.3)

I'm thinking maybe try install pip and install 'web' package manually. But before I go there any idea as to why I get contradicting mesages?

Thanks @HenrikEnquist - confused myself thinking the actual python program could exist outside the venv where the script then would point to the dependencies. But now see this logic could fail given not all revision of Python being compatible.

Service start string then become:
ExecStart=/home/pi/camilladsp/camillagui_venv/bin/python /home/pi/camilladsp/gui/main.py

FIR convolution, does it run at Capture or Output Fs?

It would be nice to see the up or down sampling step as a box in the pipeline plot. And the we would know as a Conv filter would be plotted either after or before this.

(Its the capture - rigth?)


An other matter:

If one fail with Fs etc using the Conv filter type, big surprise incl. hearing damage may occur if one is not careful... I have had such an event. Scary really... and hurtful.

Remember, CDSP is very often used in active X-over and amps are directly connected after DACs. Volume is done upstream so full pelt out here...

I think a safety rule to let output play would be a good thing...

- If all first 1000 samples (or at the most, a chunk) coming out of the pipeline are either 1 or -1 , don't forward them to the port and stop with an Error. If it was indeed "music", it should be reported to the WHO ;-)

There is a new gui release! The main new feature is import. You pick a config file, and then you get a prompt to select what parts of the config to import. can import selected parts of a config.
It supports camilladsp v1 and v2 (including the partial configs exported by REW), EqualizerAPO, and Convolver.

Henrik, I am trying this out and having trouble reading a "partial configs exported by REW" file so I can select filters and the associated pipeline steps.
I have attached the offending file created by REW V5.30.9 . Can you tell me where I'm going wrong, please.

I do like the coloured lines in the pipeline plot.

Only capture runs at capture_samplerate! The resampler is always the first step, all filters come after it.

Yes that's probably a good idea, then there can be no confusion. I'll add this in the next major version.

Hmm basically a sanity check, yeah could be good. I'll think about it.
For now, you could put in Limiter filters while playing around.

I upgraded from 2.0.0. to 2.0.3 and my lines has disappeared in the pipeline plot. I also upgraded to Pycamilladsp 2.0.2 and Backend 2.1.0. I tried a browser refresh, but it dosen't help. Does anyone have an idea of what is wrong?

I have a problem with config files not being automatically activated in v2.03 on a raspberry pi 4 and Zero 2w. I have it set up according to the excellent instructions on audioscience review, and everything works except that I have to go into the GUI and 'Apply to DSP' before the config that's active in the statefile is loaded into the DSP and then everything works fine, until I reboot. This is a problem when I'm running off grid without my usual wifi. The service that starts Camilla DSP has these lines in it (among others):

User=pi
WorkingDirectory=~
ExecStart=camilladsp -s camilladsp/statefile.yml -w -g-9 -o camilladsp/camilladsp.log -p 1234

I tried adding a default.yml config and referencing it at the end of the ExecStart line, but that didn't work either. Any suggestions?

the thing is, I haven't used command line software since late 1983, so the prospect of it is more than a little daunting. I'm stuck at the download page, as I'm not sure where to even begin.

I agree using/learning command line is daunting. Have you been able to make any progress? I’m currently trying to figure out how to update some firmware for a minidsp plate amp. I’ve yet to figure out exactly how to input commands properly.
I’ve been searching the web for a tutorial that is a step by step instruction.
