That's right, ambisonic. I was thinking though, since in the case of binaural spatialisation, an anechoic source can be spatialised (in an angular sense) through convolution with various impulse responses taken at various angles (and I guess interpolation is performed for angles between those angles used to make the impulses), could a source be spatialised in an ambisonic array by convolution (and later ambisonic decoding) with a series of impulse responses taken at various angles? Further, if these angular measurements were taken at various depths (distances between impulse source and mic), is it possible to impart the perception of various depths of the rendered sound-source?
Hope this makes sense. Em Sex, 2013-05-03 às 13:02 +0200, Augustine Leudar escreveu: > Youre only interested in ambisonics right ?
