Designing Sound in SuperCollider/Rolling can

Fig 31.3: simple approximation to a drink can
The four clear resonances are identified using a spectrogram of a can.

Fig 31.6: a repeating roll pattern
This simulates the regular turning of the drinks can. Since it's a control signal we'll plot it rather than play, for now.

Fig 31.8: putting it all together
(You must have run figs 31.6 and 31.7 to get their functions defined.)

The sound of a can rolling a little and coming to a stop.
