Efficient Phantom Source Widening and Diffuseness in Ambisonics
Object-based spatial audio considers virtual sound sources having a width/diffuseness parameter. This parameter aims at controlling the perceived width or diffuseness of the auditory object, or phantom source, created by the renderer. Width/diffuseness provides an important salience parameter that is independent of perceived direction and timbre. A highly efficient sparse filter structure for two-channel stereophony was described and tested recently, but it becomes ineffective for most parts ofdoi:10.14279/depositonce-12 fatcat:j4s5bq6yqncurjtuovyllktgke
