RPi + CamillaDSP Tutorial

nevermind - found the problem: When fiddling around with several different CDSP config files, I forgot to add the 1kHz filter within the "pipeline" tab. Seems to work fine now.
Nevertheless it's so cool this forum exists, with so many helpful people and very useful resources.
Thank you!

Will wait some time then ☺️
 
I wanted to add a "tilt" control to the Shortcuts page of the GUI, and it was really easy.

First, add the Tilt filter to your config

filters:
Bass:
description: null
parameters:
freq: 85
gain: 0
q: 0.9
type: Lowshelf
type: Biquad
Tilt:
description: null
parameters:
gain: -5.2
type: Tilt
type: BiquadCombo
Treble:
description: null
parameters:
freq: 6500
gain: 0
q: 0.7
type: Highshelf
type: Biquad

shown here between the suggested Bass and Treble filters. Then add an entry for it in camillagui/config/gui-config.yml:

custom_shortcuts:
- section: "Equalizer"
description: "To use the EQ, add filters named \"Bass\" and \"Treble\" to the pipeline.<br/>Recommented settings: <br/>Bass: Biquad Lowshelf freq=85 q=0.9<br/>Treble: Biquad Highshelf freq=6500 q=0.7"
shortcuts:
- name: "Treble (dB)"
path_in_config: ["filters", "Treble", "parameters", "gain"]
range_from: -12
range_to: 12
step: 0.5
- name: "Bass (dB)"
path_in_config: ["filters", "Bass", "parameters", "gain"]
range_from: -12
range_to: 12
step: 0.5
- name: "Tilt (dB)"
path_in_config: ["filters", "Tilt", "parameters", "gain"]
range_from: -12
range_to: 12
step: 0.1

Then refresh the page to see the Tilt control. Tilt can be from -100 to 100 dB, but +/- 12 seems sufficient and is an easier to use range.

I guess you could basically control many other filters this way which is useful to know. Probably any filter with a gain function?

I have a convolution filter with 0.5dB/oct slope, and used +/-6 dB adjustment, which was enough to make the in-room response flat. Cool to satisfy curiosity about different slopes. But I don't see myself ever adjusting this again. 0.5dB/oct is just perfect. If for some reason I had to use a tilt-filter, I would set it once and never touch it again.

But as I said, this could maybe come in handy for something else in the future, so thank you for showing how this works.

The idea was to use this to select a room correction target. Instead of creating a bunch of targets and trying to select among them, I created one flat-in-room set of correction filters and then adjusted the tilt until I liked the tonal balance. It was much easier to get a feel for what more or less tilt sounds like by adjusting a slider. I ended up with a Tilt with a gain of -5.6. I then used Acourate's IIR tool to create a similar target for more permanent use. I'd like to do something similar for B&K-type targets rather than just a simple tilt.

Yes, it was in no way meant to bash your use of it (I hope it didn't came across like that). We all have different speakers, use cases, and probably develop our own firm ideas about the right way to go about things.

CamillaDSP has become a hobby of itself now, so it was appreciated to learn something new about it.
 
Hi @HenrikEnquist and forum, I would be very happy, if someone could please explain me, how I could change the CamillaDSP default startup volume - meaning the volume, that CamillaDSP always goes back to, after a restart. Is it possible to either tell CamillaDSP to always start with the last volume level, or define a new default/standard volume level? I'm using the Wiim Pro Plus streamer via an optical to USB converter for audio in - and use the Wiim volume control. Thus, I like the CamillaDSP volume to always stay on 100%. As I'm new to Linux and Raspberry, I'd very much appreciate a noop friendly instruction. Thanks a lot and kind regards :)

(For audio output I currently use the DAC8x, but I like to use three individual DAC boards connected via the native I2S GPIO out, once I2S is availalble via MCLK at the Raspi5 GPIO pins.)
 
I am in the process of setting up a raspberry pi 4B with CamillaDSP, and while in general it looks quite promising, there is one problem that I can't figure out so far.

The capture device is USB gadget, the playback is a Motu M4. The g_audio module parameters are "c_srate=48000 c_ssize=4 p_chmask=0 c_chmask=63". On the host system I am running "speaker-test -D hw:Gadget -c 6 -f 160 -t sine -r 48000 -F S32_LE", and here is the problem: in about 40% of the times there is a distinct sound glitch that repeats every few seconds. Here is what it sounds like: link.

I tried connecting the RPi to another host, using different USB cables and other random and not so random changes to the configuration, but the problem persists. It seems to be somehow specific to the USB gadget configuration, because I could not reproduce it using the ALSA loopback device. When this reproduces, there is nothing out of the ordinary in the CamillaDSP logs.

At this point I feel quite stuck, so any suggestions how I could troubleshoot this further would be very helpful.

Here is the CamillaDSP config:

Sorry, missed a word, meant to say that there is nothing out of the ordinary in the logs. But just to make sure will reproduce again and post the logs later today.

Have you tried lowering the target_level value for rate adjust? I think the recommended value is ~75% of chunksize (if using CamillaDSP v2), so maybe try 768 in your case.

I did, doesn't help, unfortunately.

I did notice one new thing, though. Sometimes the beginning looks like this:

And if this stalled/resumed event happens at the beginning, the audio seems to always play correctly without glitches.

IMO the safe value is 75% of buffer size, that is 1.5 of chunksize for v.2 (buffer = 2 chunks) and 3 chunksizes for v.3 (buffer = 4 chunks).

IMO the safe value is 75% of buffer size, that is 1.5 of chunksize for v.2 (buffer = 2 chunks) and 3 chunksizes for v.3 (buffer = 4 chunks).

Oops got confused between buffer and chunk size, thanks for the clarification
 
Hi, I am having decent trouble getting CamillaDSP GUI to be accessible and running on a new Ubuntu LTS 24.04 build.

I've checked the IP address, all is correct.
http://my IP address:5000/gui/index.html

DSP

[Unit]
Description=CamillaDSP
After=default.target
StartLimitIntervalSec=10
StartLimitBurst=10

[Service]
Type=simple
User=ubuntu
WorkingDirectory=~
ExecStart=camilladsp -s camilladsp/statefile.yml -w -g-40 -o camilladsp/camilladsp.log -p 1234
Restart=always
RestartSec=1
StandardOutput=journal
StandardError=journal
SyslogIdentifier=camilladsp
CPUSchedulingPolicy=fifo
CPUSchedulingPriority=10

[Install]
WantedBy=default.target

GUI

[Unit]
Description=CamillaDSP Backend and GUI
After=default.target

[Service]
Type=idle
User=ubuntu
WorkingDirectory=~
ExecStart=python3 camilladsp/camillagui/main.py

[Install]
WantedBy=default.target

Any ideas? Is the username different to my Linux Login?

I have completed two fresh installs now. No good either time. Following the instructions verbatim.

Seems DSP and GUI are running, I just can't access the WEB GUI, which is odd.

Default port is 5005, is 5000 a typo in your post?
