A thread for the discussion of ITD, it's effects and usefulness in stereo reproduction via loudspeakers in a room.
I found this paper interesting https://core.ac.uk/download/pdf/101155.pdf

A nice read, thanks.
A simple gloss over shows they had subjects talk about the width of image as modified by an underlying LF signal from 5 hz up to 100.
Interesting, as that could indicate the width will be amplitude dependent.
Also, they found speaker location angles of 30 and 90 presented differently.
The killer I see is the reflection tests, the room plays a very important role.
Again, thanks. I will read it in detail later.

Wittek & Theile wrote a paper on the (microphone) recording angle based on localization curves.
Although the curves differ between the different publications (due to the methods used), it can be seen that for small to medium shifts of the phantom source the relationship between ITD or ILD and shift is fairly linear, while at the more extreme shifts it needs more difference between the channels.

Hi folks
I think that this area has been investigated before by the engineers at EMI in 1957 plus some later papers.
Here is a copy of the original research paper plus a later one by Bennett, Barker and Edeko.
Happy listening
