waves, the hearing system uses two strong cues for estimating the apparent
direction of a sound source. Namely, interaural intensity and time differences
(IID and ITD) are jointly used to that purpose. IID is mainly useful above
1500Hz, where the acoustic shadow produced by the head becomes effective,
thus reducing the intensity of the waves reaching the contralateral ear. For this
high-frequency range and for stationary waves, the ITD is also far less reliable,
since it produces phase differences in sine waves which often exceed 360

Beeldmanipulatie neemt in Claerbout’s werk een bepalende rol in. Foto’s worden met films gecombineerd of verschillende films worden over elkaar gelegd en in versneld of vertraagd tempo afgespeeld. Zijn technieken zijn weliswaar gestileerd van aard maar hebben verbluffende beelden tot gevolg. De video installaties verrassen in hun ogenschijnlijke eenvoud. door de zorgvuldig gekozen composities.

FRUITION: perceptual time ‘gap’ as location for knowledge –
Mnemonic Present Un-folding
Abstract. In developing my practice/research I analyse the interchange that takes place between audience and performer from within the paradigm. My own art practice is grounded in Merleau-Pontì’s concept of chiasm and intertwining and Amelia Jones’s reading of it, although I take a conceptual distance from Jones’s, constituted by considering time travel in artist-audience interchange taking place during mediatised performative events, here addressed as fruition stage. The time element comes from the production and incorporation of the video documentation in the event itself. The purpose of my review will be to introduced the implications and significance of the perceptual gap between audience and performer’s in the moment of fruition of the piece Mnemonic Present Un-folding.
