Hi,
I agree with Stefan.
One would have to undo a binaural encode to something else, then do a
dynamic head-tracked re-encode.
I did once try to transform a binaural signal to first order B-Format
ambisonics with height using Max/MSP using a fairly simple algorithm.
It sounded reasonably convincing, but was almost certainly not
correct in any sense. It was just an attempt to use binaural files in
a 1st order ambisonic environment along with mono, stereo, MS etc.
Ciao,
Dave

And how can you apply head-tracking to a binaural recording?
Last time I have argued that B format recordings allow (easy)
application of HT, binaural recordings actually not.
You can't reconstruct the real or B format sound field from a
binaural recording. If not, I don't see how you could apply HRTF
data sets to calculate a (new) binaural representation -
corresponding to your current head orientation. I am very open for
smart algorithms, but still...
No way, IMO!
Best,
Stefan
