Signal generation for binaural signals

摘要

Abstract There is described a device for forming an inter-similarity decreasing set of HRTFs for modeling an acoustic transmission of a plurality of channels from a virtual sound source position associated with the respective channel to ear canals of a listener. The device comprises 5 an HRTF provider for providing an original plurality of HRTFs implemented as FIR filters, by looking-up or computing filter taps for each of the original plurality of HRTFs responsive to a selection or change of the virtual sound source positions. The device also comprises an HRTF processor for causing impulse responses of the HRTFs modeling the acoustic transmissions of a predetermined pair of channels to be delayed relative to each other, or differently modifying-in 10 a spectrally varying sense-phase and/or magnitude responses thereof The pair of channels are one of a left and a right channel of the plurality of channels, a front and a rear channel of the plurality of channels, and a center and a non-center channel of the plurality of channels. 6658917 1 (GHMatters) P86308.AU.2 SOPHIER
