DBAP GUI done

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 – initial DSP implementation

A first implementation of the audio processing is complete. Currently, it uses the original DBAP algorithm with no convex hull, so sound sources located outside of the speaker field will not sound convincing.
