Level-of-detail is a concept well-known in computer graphics to reduce
the number of rendered polygons. Depending on the distance to the
subject (viewer), the
objects' representation is changed. A similar concept is the clustering
of sound sources for sound spatialization.
Clusters can be used to hierarchically organize mixels
and to optimize the use of resources, by grouping multiple sources
together into a single representative source.
Such a clustering process should minimize the error of position allocation of
elements, perceived as angle and distance, and also differences between
velocity relative to the sink (i.e., Doppler shift).
Objects with similar direction of motion
and speed (relative to sink) in the same acoustic resolution
cone and with similar distance to a
sink can be grouped together.
Keywords:
Sound spatialization, resource management, audio rendering, clustering, and human perception
