Sound synthesis

The sound synthesis is a method for making artificial or modification of natural sounds.

The first widespread form of sound synthesis Subtractive synthesis, mainly because it is easy to realize alone with analog circuits. FM synthesis has been successfully used only with the transition to digital technology, as it requires high demands on the stability of the frequency to be coupled with each other oscillators. Even more complex is the Additive synthesis, since the number of required oscillators multiplied to produce the overtones of a sound compared to FM synthesis.

Wavetable synthesis is no longer to be realized with analog means, but nevertheless needs less computational power than the granular synthesis and physical modeling, which make sense can only be used on modern computers.
