3. Microtuning

If you have tested different waveforms, you may ask: “which one sounds most like a synthesizer?”

                                The answer is “None”!

Every constant vibration sounds boring in the long run. The ears want to be entertained, so you have to make the sounds a little more dynamic to get the ears interested.

This can be achieved by a simple trick: Synthesizer use not only one but two (or several) slightly detuned oscillators and mix the signals together. The result is a “fat” sound with permanently changing overtone spectrum due to the interference of the waves with the different frequencies.

With this trick you can make a fat, roaring synthesizer sound with every dull vibration. Microtuning is one of the most powerful tool in the sound design.
