Subject: Re: [Sursound] A submittal for a patent on Ambisonics?

It looks like a method for binaural rendering with multiple distance HRTFs.

Ambisonics could be one of the inputs, but it seems to be aimed more at
object based virtual reality, where the listener is more likely to come
very close to an audio source.

Most HRTFs are currently measured at 1m distance, so any objects closer
than 1m are not currently rendered correctly.

Far field HRTFs are closer to plane waves, whereas close up audio objects
emit more spherical waves, creating greater differences in interaural time
difference (ITD).
