Designing Sound in SuperCollider/Telephone bell

29 Old-style telephone bell
In the book, one partial of the resonance is modelled using a sinewave, modulated by an envelope that dies away on a quadratic-shaped curve. Groups of three such oscillators are then made.

Here we take advantage of a built-in unit in SuperCollider which does quite a lot of the work for us: Klank. A difference: it gives exponential rather than quadratic decay - which is not too bad since exponential decay is often what you want.

Fig 29.12: a striker sound
As described in the book, a brief click is all we need to approximate this part of the sound.

Note: leave the bell playing while you add the following effect:

If you have sc3.3 or later, you can visualise a frequency representation of the filter's effect:

We will re-use the SynthDef from fig 29.14, so make sure you have run that so that the server has that SynthDef. (But stop the sound, if it is still running.)
