Center "look" of measured HRTF binaural decoders

[joslloand]

The binaural decoders generated from measured HRTFs (Listen, CIPIC) currently encode without regard to the individual subject's "look direction". That is, it is assumed each subject is looking at [0, 0] during measurement. In practice, the true look direction varies somewhat with each subject.

Measuring the (band-limited, "pinked") normalized intensity vector will give a reasonable measure of the true "look" of each subject.

Correcting for "look" will bring greater consistency to measured binaural decoders.
