This is the additive part of Risset's 'Linear and Exponential
Decay Experiments'. In his score the composer uses only three
parallel building blocks, but this can be extended to any number,
if there is a wish to do so. 


In section 1 the waves with the higher harmonic content decay
faster. This situation is often encountered in natural vibrating
systems. The example of section 2 adds a slight detuning to add
liveliness.  In section 3, the waves with lower harmonic content
decay first (not often found in nature), and section 4 adds a
small detuning once more. The noise in sections 3 and 4 stems
from the foldover components of the square wave f31. Section 5
repeats section 1, and the last section detunes the three
oscillators just a little more than was the case earlier on.
