GUI for DBAP complete from Trond Lossius on Vimeo.
Some finishing touches for now: Introducing a pop-up menu for choosing whether to edit position of sources (input channels), destinations (output channels) or none. I’m contemplating showing and hiding the two tables in the right column based on menu choice, and possibly make them inactive (uneditable) when editing mode is set to “none”.
But for now it is more interesting to move on to implement the DSP algorithm itself. Rather than implementing DBAP as first published by me, Pia and Theo in 2007, I contemplate testing out the improved algorithm proposed by Jacob Sundstrom in 2021.

DBAP GUI is almost complete from Trond Lossius on Vimeo.
The GUI for the DBAP plugin is almost complete. What remains to be done is to add a menu or button to choose whether to interact with and edit the positions of inputs or outputs. When that is done, it is time to implement the DSP process.

Juce – MVC with custom XY Pad component from Trond Lossius on Vimeo.
After two failed attempt, the third attempt succeeded.
This is a fairly simple plugin, and is mostly meant as a study (étude) into a specific programming problem when developing plugins in C++ with the Juce framework. The plugin controls gain and pan. ValueTreeState enables model-view-control separation, and as compared to an earlier study, it expands by implementing a custom component in the form of a two-dimensional control pad that controls gain as well as pan.
In figuring this out, I have drawn extensively on YouTube tutorials by Akash Murthy and Florian Mrugalla, and not least source code for the IEM ambisonic plugins. From the latter, I have in particular studied code for the SpherePanner component and the ProbeDecoder plugin.
This brings me one step further towards implementing DBAP as a VST plugin. That is itself a study towards porting Ambisonic Toolkit higher-order functionalities from SuperCollider to plugins. I hope to be able to embark on that journey later this year.

Back to the drawing room again…

I am slowly progressing on a Distance-Based Amplitude Panning (DBAP) plugin. I now have parameters set up in AudioProcessor, and in the Editor, the table components for setting the source (input) and destination (output) coordinates work. The next step is implementing the XY pad that visualises and offers interaction with source and destination positions.

Juce MVC demo and study from Trond Lossius on Vimeo.
A further test/study of how to use ValueTreeState with child components in Juce, ensuring proper model-view-controller (MVC) separation. Figuring this out is a prerequisite to be able to build plugins of any degree of conplexity.

Juce TreeValue test from Trond Lossius on Vimeo.
A small test of using TreeValue in Juce when programming a VST3 plugin. This seems to enable MVC (model-view-controller) separation. In this example two sliders in the editor are associated with, and listens to, the same paramter. It seems to work well when changing the value using one or the other slider, as well as when the parameter value is changed by the host.

A bonus of getting to know the source code for the IEM ambisonic plugins is that I can mod them so they can be resized in Reaper.

Two Dots Moving from Trond Lossius on Vimeo.
After three days of intensive coding, two dots are moving…
Please listen using headphones.

AntiRSI is a handy little macOS app that encourages shorter and longer breaks while at the computer to avoid muscle strain and tension. I first downloaded it over a decade ago and have always copied it when migrating to new laptops. With the latest migration to a computer running Sonoma on an M2 processor, it stopped working.
It appears that the original developer no longer maintains it, but I found a more recent fork on GitHub. I checked out and compiled it, and it instantly works. Nice!
