"The complexity of different points of sound observation in a space"
A Space is prepared using multiple rotating loudspeakers (Leslie speakers), placed on the floor, on tables, on the walls and on the ceiling. The listener himself becomes a physical agent of sonic variation. Walking through the space, sitting, lying, standing straight or in crooked posture, also all kinds of different head and body movements will foster a diversity of sonic nuances. This highly unusual listening situation is provoked by the disposition of the sound sources on the ceiling, on tables or on the floor. Sound signals originating from different directions are altered by way of electroacoustical processing. Doppler effects caused by the rotation of the sound sources cause acoustical beats. Moving away from the listener by way of rotating its source a sound will lower its perceived pitch. At the same time the sound source draws closer to the opposing wall which thereby will receive a higher pitched sound and at the same time reflect this sound in the listener’s direction. This is happening all the time in all spacial directions.
