Low frequency envelopment is perceived through fluctuations in azimuth There is not time in this paper to discuss the theory of interaural fluctuation
{"Image DocumentName": "Low frequency envelopment is perceived through fluctuations in azimuth", "Image ImageDescription": "There is not time in this paper to discuss the theory of interaural fluctuations. See the references. In briefest outline: Reverberation in large spaces is chaotic in its direction of incidence, fluctuating randomly even during long notes. Large spaces are very seldom in steady-state, so the ITD at the listener is in constant state of change. We perceive this fluctuation as envelopment \u2013 the sense of being inside the sound. The perception is VERY DIFFERENT from having the sound inside the head! Reverberation in small spaces does not fluctuate. because for most musical notes the reverberation quickly reaches a steady-state condition. To reproduce these fluctuations we must first record them. This is easy. Then we must find a way of reproducing them at the listening position. This is hard.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
