Walking towards and between two parked cars
As a further technical (not yet perceptual!) verification
of information preservation in what we could call ``earsight,'' the
following experiment was done using the above image frames.
Using The vOICe Java application, 32 kHz 16 bit .wav
sound files were written for the individual sonified frames.
After that, The vOICe Java application read these sound files for
spectrographic reconstruction. In the animation below, you
see the original 64 × 64 pixel image frames before
(left) and after (right) sonification and reconstruction.
An exponentially distributed [500 Hz, 4 kHz] frequency interval for
1.05 second soundscape frames was used in the sonification. This
is the default setting for the applet/application. The
``well-tempered'' exponential distribution causes the striped
Moiré-like distortion patterns, but the sounds are for
auditory perception more pleasing than, say, an equidistant frequency
distribution. You can observe that this choice did not degrade resolution
too badly.
