The time-frequency resolution of human hearing has been taken into account for long time in perceptual audio codecs. Recently, the spatial resolution of humans has been exploited in time-frequency processing as well. This has already lead to some commercial applications. This workshop covers the capabilities and incapabilities of human spatial hearing and the audio techniques that exploit these features. Typically the techniques are based on the estimation of directional information for each auditory frequency channels, which information is then used in further processing. The application areas discussed in the workshop include audio coding, microphone techniques, upmixing, directional microphones, and studio effects.
