David, I hope we're not in danger of hijacking Curt's thread. I think
this is still apropos to the 'wavy' thing:

It seems serendipitous that Arnthor's post 'Reykjavik Marathon' showed
up with yours this morning.
I spent some time listening to take 2 (10km) with phones, as suggested
and then with speakers. Around the middle of the file, where the main
bulk of runners is passing, the background din gets quite 'fluttery'
(hmm, wavy or splashy?) in the phones, but I find it to be considerably
less so on speakers. I think the effect (either way) demonstrates your
comment. It also brings me to something I've been wondering about
forever, but has been front and centre since reading some other posts
here over the past few weeks.
Does it make sense to listen to co-incident arrays on headphones? Or,
for that matter, spaced arrays on speakers?
Why do I hear so little direction or comment on how a file should be
heard, even given that commercially it would be a nightmare to have to
produce for both methods of playback, and impossible for multi-track stuff.
If I understand the mechanics correctly, a co-incident array passively
preserves ITD and re-constructs it over a properly arranged stereo
speaker system. A spaced array records ITD and reproduces it on phones
but, if played back over speakers, effectively doubles it(?). In either
case, doesn't a mismatch create equal or possibly greater phase problems
(<1.5kHz at playback time) than at the time of recording?
Thanks for any clarity that is offered!
Keith
