I’ve taken the trig for designing uncoupled loudspeaker arrays and made it into its own piece of software. It is a big UI improvement over the old Excel sheet, it draws a diagram of the array, and it can export arrays as XML files for Meyer’s MAPP Online Pro. It’s written in Python, but I’ve created standalone versions for both Mac and PC.
Each array parameter is on the left, with radiobuttons to select which should be calculated. With any three parameters, it’ll spit out the fourth automatically, and redraw the diagram. You can have a bunch of loudspeakers, with quantity entered manually or calculated from a listening plane length/perimeter.
To export an array to MAPP, click the button and follow the few steps to enter a loudspeaker model and ‘save as’ destination. In MAPP, go to File->Import->Import Individual Loudspeakers…, and that’s it.
Here’s the same array from above dropped into our MAPP file:
This could also come in handy for building arrays independently of the trig, i.e., it’s a quick way of creating an array of a bunch of loudspeakers, like a 50-element straight subwoofer array.
