  Audio scene cartography for real or simulated stereo recordings is presented.
This audio scene analysis is performed doing successively: a perceptive
10-subbands analysis, calculation of temporal laws for relative delays and
gains between both channels of each subband using a short-time cons\-tant scene
assumption and channels inter-correlation which permit to follow a mobile
source in its moves, calculation of global and subbands histograms whose peaks
give the incidence information for fixed sources. Audio scenes composed of 2 to
4 fixed sources or with a fixed source and a mobile one have been already
successfully tested. Further extensions and applications will be discussed.
Audio illustrations of audio scenes, subband analysis and demonstration of
real-time stereo recording simulations will be given.Paper 6340 presented at
