1. Introducion

How can we make a (interesting) sound?

As a rule, sounds are generated in 3 steps:

  1. A generator creates a vibration in the range of 30-10000 Hz

  2. A modulator shapes the contour of the loudness of the tone.

  3. Finally a DSP (Digital Signal Processor) adds acoustic effects like

    reverb, echo, filter … to the audio stream.
