 == Introduction to Audio Frequencies ==
-(Needed: text)
+Tonal sound - ones that have an identifiable ''note'' - have a predominant '''frequency'''. This frequency is described in Hz, or cycles per second. It is easiest to look at a sine wave, and how the speed of the sine wave determines the frequency that can be measured. If a sound takes one second to go through its entire cycle, it has a frequency of 1 Hz. If it goes through 500 cycles every second, it has a frequency of 500 Hz. Audible sound generally ranges from 20 Hz through 20,000 Hz (also called 20 KHz), and obviously represents a ''lot'' of data.

+When working with audio, we tend to think of various processes and their "roles" in the audio design process. We talk about the four types of role as:

 == Introduction to MSP Audio ==
-(Needed: text)
+To this point, we've been using Max objects - objects that work with create, process and modify events. Historically, the objects that work with audio are called MSP objects (since they were previously sold as a separate package called MSP), and are easily identified because they all end with a tilde (~) in their object name. Thus, the {maxword|name=cycle} object and the {maxword|name=cycle~} are two different object, with the second representing a audio (MSP) object.
