SOUND EXAMPLES
(only to listen on headphones. these sounds doesn't make any sense if played from loudspeakers)

Approach 1: random scan (with four original sound sources)

• sound source: FM synthesis

  no object detected in the proximity scan --> mp3
  one object exisit at 135 degrees azimuth (right rear) --> mp3
  one object moving in a circle starting from 0 degree --> mp3

• sound source: recording of water sound
  
  no object detected in the proximity scan --> mp3
  one object exisit at 135 degrees azimuth (right rear) --> mp3
  one object moving in a circle starting from 0 degree --> mp3

Approach 2: rotating plane (with 16 orginal sound sources on the "edge" of the plane)

1 sound source scanning --> mp3
2 sound sources scanning (in a dipole position)--> mp3
16 sound sources scanning (no object detected) --> mp3
one object detected exisiting at 135 degrees azimuth (right rear) --> mp3
another object with "narrower width" added to the previous object --> mp3
above 2 objects rotating, maintaining a relative phase with each other --> mp3

This project is still under development, more sound examples will be uploaded soon...
