Soundscape is unrepeatable as the day unfolds within the THRESHOLDS installation. Sound changes tend to develop very slowly during the day and quite quickly by twilight; at nighttime sound qualities shift according to people's intervention.

Original looping source-samples in the Lisa software buffer last minimum about 30" and maximum about 3'5". These loops are re-sampled and processed in real-time according to parametric values (incoming 127-range ascends to 512-range). Re-sampled loops might get as short as 1' if sample length or sample start are audio-parameters mapped to a controller (light sensor). Likewise, if tuning is one of these parameters then the sample will stretch and contract.

Actual sample collection/ selection, edit and control-mapping are drafted but not definitely established yet; many decisions depend on the real site-specific context. The following audio material might provide an idea regarding the field of present possibilities (please also try out overlapping multiple sound layers simultaneously); yet these can only be heard in musical imagination.

BRIGHT  OUT-DOORS:
slow daylight changes play massive sound density (water + field ambients); soundscape controlled by LIGHT SENSORS 1 and 2; click for a 3' re-mix and corresponding explanation (4MB)
DARK  OUT-DOORS:
interactive shadows play upon NYC audio-pictures (field ambients + people); soundscape controlled by LIGHT SENSOR 4; click for a 3' re-mix and corresponding explanation (3.3MB)
TWILIGHT  OUT-DOORS:
all LIGHT SENSORS 1, 2, 3 and 4 active in the soundscape; PLEASE CLICK and REPEATEDLY to simulate the overlapping sound-layers; day-peak for peak audio behavior; read about it in the NOTES
