Using Camilladsp with moOde 7 – Part 2

In part I I explained how you can get CamillaDSP working with moOde 7. In the upcoming release moOde 7.1.0, we have improved the integration a lot. No need anymore for any dirty command line work. Configuration files can edited with a web interface.


The features are:

  • Management of CamilllaDSP configuration files.
  • Management of impules response files for the convolution filters.
  • Uses the alsa_cdsp module in config_cdsp mode, which passes the samplerate and capture format to camilladsp.
  • Patching the alsa_cdsp configuration with the correct camilladsp configuration file.
  • Automatic patching of the configuration files with the correct output device and sample format. Of course it can also be disabled.
  • Custom mode where the alsa_cdsp and camilla configuration are not managed by moOde.
  • Quick convolution mode
  • You can start camillas own gui from moOde to edit configuration files.
  • Software version are bumped to 0.5.0 beta 2.
  • Camilla did get its own configuration page which look like:


In the configuration selection box you can select a configuration to use. There are three special ones:

  • Off – you already guessed it; turns off CamillaDSP
  • Custom – When chosen alsa_cdsp and camilladsp and related are not managed by moOde. This makes it possible to create a setup different that the default moOde provided. Use only if you know what you are doing.
  • Quick convolution filter – instead of providing you own camilla configuration file, there is a template for quick setup of a convolution filter. For example perfect for AutoEq headphone corrections.

All other choices are the available configuration files. In the section Pipeline configuration those can be managed,

Quick convolution filter

Camilladsp works with configuration files. For basic convolution filter a template is present.

You only have to provide four settings to get it working.

Quick convolution filter

The left and right impulse responses can be uploaded in the section convolution file.

The pipeline configuration contains:

  • a mixer
  • 2x master gain
  • 2 convolution filter

Below is the graphical form of it:

For headphone users among us, the project AutoEQ provide parametric eq and convolutions files for equalization you headphone.

Pipeline configuration

Here you can manage the pipeline configuration files, including checking the configuration and show a graphical form of the pipeline.

A few configuration files are provided. Those are not useful for anything then to test camilladsp works correctly.

The easiest way to start building your own configuration files is to copy an existing and open the provided camillagui to create your filter pipeline.

Alternative you can upload you own premade configuration files. See the camilladsp website for the format of the configuration files.

Convolution file

Impulse response files for the convolution filters can be managed here. With the INFO button you can show some basic information about the impulse response file. See camilladsp for information about the supported file types.

Pipeline editor

The pipeline editor is the web interface provides by the camilladsp project it self.

The status shows if the gui is already running or not. If not it can be started by toggling the button.

The expert mode show some settings you only need to change or check when use custom config alsa_cdsp or custom output device(s).

camillagui is started as a systemd service called camillagui.

On start the camillagui will load the active configuration file. On apply the changed configuration will be activated and saved.


At the left side the clipped number of samples are shown. Ifthat is the case you can reduce the input with a gain filter at the front of your pipeline.

At the filter section self there is a plot button which provide the gain an phase response:
