✤ Klang

✤ Klang is a bank of fixed frequency sine oscillators. Klang is more efficient than creating individual oscillators but offers less flexibility.

✤ DynKlang

DynKlang is a bank of sine oscillators. It is less efficient than Klang, as it is basically a wrapper around SinOsc UGens in

order to provide a similar interface to Klang.

✤ https://en.wikipedia.org/wiki/Colors_of_noise

✤ GrayNoiseis random white noise subjected to a psychoacoustic equal loudness curve over a given range of frequencies, giving the listener the perception that it is equally loud at all frequencie.This is in contrast to standard white noise which has equal strength over a linear scale of frequencies but is not perceived as being equally loud due to biases in the human equal-loudness contour.

Subtraktive Synthese

✤ Klank

✤ Klank is a bank of fixed frequency resonators which can be used to simulate the resonant modes of an object. Each mode is given a ring time, which is the time for the mode to decay by 60 dB.
