Abstract
A method for visualizing a directional sound activity of a multichannel audio signal, wherein the multichannel audio signal comprises time-dependent input audio signals, comprising determining a directional sound activity vector from virtual sound sources determined from an active directional vector and a reactive directional vector determined from time-frequency representations of different input audio signals for each one of a plurality of time-frequency tiles; determining a contribution of each one of said directional sound activity vectors within sub-divisions of space on the basis of directivity information related to each sub-divisions of space and directional sound activity level within said sub-division of space by summing said contributions; displaying a visualization of the directional sound activity of the multichannel audio signal by a graphical representation of directional sound activity level within said sub-division of space.
