As a new researchers in the field I was very pleased to find this toolbox. Just a few minor points:
Would be nice to see some more links to source materials, e.g. https://ccrma.stanford.edu/workshops/gaffta2010/spatialsound/topics/amplitude_panning/mate...
In VBAP&VDP/Tutorial.pdf, in Eq(12) shouldn't the gain factors [g1 g2] be squared?
In Voutputfiles.m are you actually delaying the signal? It looks like you are just setting the first n samples to 0, rather than adding n 0 samples to the start (?)
Other than that, the package seems pretty good. The inclusion of pdfs is especially nice. The code itself could be neatened up a bit though - e.g. correct function names to match file names, remove lurking .asv files, improve the meta info in the comments (creation dates etc.), perhaps replace some of the for loops with indexing and some of the strcat's with sprintf's.
