Re: [Sursound] Hooke: First Bluetooth Binaural Microphone
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 From: Stefan Schreiber Date: 28 June 2015 01:44:45 BDT To: Surround Sound discussion group Subject: Re: [Sursound] Hooke: First Bluetooth Binaural Microphone Anthony Mattana wrote: We are currently in talks with software spatialization companies regarding adding an algorithm that would allow Hooke to be used as a head tracking audio playback option for VR scenarios. And this could be added to your Hooke via a OTA software update months after you purchase the headphones :-) 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 -- next part -- An HTML attachment was scrubbed...

Note carefully I said "sort of" done - ok for consumer stuff (after all, mp3 is ok for consumer stuff) but not for anything serious, except for use in compositions, where the choices are down to the composer.
