This distance attenuation can be modelled, but should ideally be a = function of atmospheric conditions depending how far away the source is. = For detailed distant natural rendering, one may also need to account for = general terrain acoustic properties. For headphone rendering, we have made our research rendered public as = Anaglyph (http://anaglyph.dalembert.upmc.fr/), free for all use as a VST = plug-in. It is geared very much towards realistic proximity rendering = with some basic far distance attenuation.=20 As with others mentioned, you should be able to automate trajectories = using various VST supported hosts (MatLab even supports it now).=20 Cordially, -Brian -- Brian FG Katz, Research Director, CNRS Groupe Lutheries - Acoustique =E2=80=93 Musique Sorbonne Universit=C3=A9, CNRS, UMR 7190, Institut Jean Le Rond = =E2=88=82'Alembert=20 http://www.dalembert.upmc.fr/home/katz -----Original Message----- From: AUDITORY - Research in Auditory Perception = <AUDITORY@xxxxxxxx> On Behalf Of Giso Grimm Sent: mercredi 13 octobre 2021 09:44 To: AUDITORY@xxxxxxxx Subject: Re: [AUDITORY] synthesizing virtual movements of naturalistic = sound sources Dear Valeriy, in addition to the suggestion of Lorenzo Picinali you may look at TASCAR - it is primarily made to simulate arbitrary movements in real-time.
