In this example Risset used data from real trumpet tones to
synthesize brass-like sounds. The amplitude envelopes of the
partials are individually specified as breakpoint functions.
(Mathews and Risset 1969)

Additionally, the frequencies of the components are random
modulated at a rate of 10 Hz with an amplitude of 4% of the
fundamental frequency. Both values are low; the random
frequency fluctuation plays a minor part in this particular tone
quality. (Risset 1969: #200)

Data for other analysis-based additive synthesis instruments is
published by Moorer: cello, trumpet and clarinet (Moorer 1985).
