The first shortcut is that most Ugens include a mul and add parameter, this allows you to include your multiplication and addition values within the call to the Ugen. Supercollider has some shortcuts that help to avoid complicated formulas using fixed values. This process has turned out bipolar sine into a unipolar sine. In the above example we multiple the SinOsc by 0.5 to reduce it’s amplitude by half. Addition is useful for adding an offset to a signal to move it into a desired output range in order to later apply it to another parameter. Multiplication Of Two SignalsĪddition by a fixed amount is not useful directly on signal output to the speakers. A signal that only uses 0 to 1 is called unipolar.

The amplitude can exceed these values during processing but to avoid clipping they must be reduced before the final output.Ī signal is said to be bipolar if it uses the full range from -1 to 1. Anything outside of these ranges will result in a hard digital distortion called clipping. These values represent the maximum amplitude that can be reproduced correctly. In digital audio amplitude is represented as a series of values from -1 to 1. I do not claim to be an expert on the subject so any feedback or corrections are much appreciated. My code samples will be in Supercollider as that is the language I am most comfortable in but these examples should be easy enough to replicate in your language of choice. This is basic information that is needed to be successful in any of these languages.

That was a lesson on of how simple math operations worked to produce effects on various signals.

In learning Supercollider, PureData, ChucK and Csound I found that there was one lesson missing from all the tutorials I read.
