Virtual Sound Source Positioning Using Vector Base Amplitude Panning
TLDR
In this paper, a vector-based reformulation of amplitude panning is derived, which leads to simple and computationally efficient equations for virtual sound source positioning, and it is possible to create two- or three-dimensional sound fields where any number of loudspeakers can be placed arbitrarily.Abstract:
A vector-based reformulation of amplitude panning is derived, which leads to simple and computationally efficient equations for virtual sound source positioning. Using the method, vector base amplitude panning (VBAP), it is possible to create two- or three-dimensional sound fields where any number of loudspeakers can be placed arbitrarily. The method produces virtual sound sources that are as sharp as is possible with current loudspeaker configuration and amplitude panning methods. A digital tool that implements two- and three-dimensional VBAP with eight inputs and outputs has been realized.read more

Distinct timescales of population coding across cortex
TL;DR: It is shown that population codes can be essential to achieve long coding timescales and that coupling is a variable property of cortical populations that affects the timescale of information coding and the accuracy of behaviour.
