These percussive gong-like sounds are realized with additive
synthesis. An exponentially decaying envelope is set onto a
number of sinusoid waveforms. 

In the first sound, all frequency components decay synchronously.
The spectrum is invariant and recalls an electronic chime.

For the second tone, the same frequency components have a decay
time approximately inversely proportional to their frequency: the
principle is followed in a flexible manner to come to a more
intricate decay pattern. Compared to the first sound, we find
more life and naturalness here.

The next tone features a different set of frequencies, again with
non-synchronous decay.


The last four tones overlap and their frequency components are
sufficiently close to each other to produce beats. (Risset 1969:
