Additive
========
* 1822 Joseph Fourier showed that some functions can be written as a sum of sines
* Using harmonics we can build up a variety of timbres
* Theoretically we could use arbitrary many sines to reconstruct almost all sounds

* Theoretically we could use arbitrary many sines to reconstruct almost all sounds
* Practically this is impossible

Contra
======
* Gets ressource intensive very fast
* Sound is often too clean, to sterile
* Its not easy to find good sounds, without FFT

Subtractive
===========
* Source with a broad spectrum -> noise
* Filter too thin out spectrum
* Gives much more "natural" sound than additive synthesis
----
Contra
======
* Restricted in what is possible
* Needs lots of experience
* Used in a lot of analog synthesizer
