One interesting thing is that while reading I noticed the files for
their experiments [1] which are referenced in the full PDF paper [2]
there seems to systematically be a tone where the left and right tones
are with inverted phase. This was immediately audible with headphones.
For example this
one:https://s3.amazonaws.com/mcd-headphone-check/v1.0/assets/antiphase_HC_IOS.wav
Reading the rest it seems this was actually intentional and a
'screening' procedure to see if people were using headphones.
Then, because this is the Linux Audio Users mailing list, they write
"Beyond requiring headphones, we also optimized our experiment for
Google Chrome (and tested it on multiple machines), and then required
all subjects to use Google Chrome as well. If any subject initiated the
experiment using a non-Chrome browser, they were required to switch to
Chrome before being allowed to participate."
Sorry to derail from the more philosophical subject :-D

(note this seems to need chrome but you can see the files by doing a
'network inspection' in the browser)
