General background information

What is an AudioGraph ?

A previous module titled Jbs2040-An Audio Graph of a Sinusoid introduced you to the concept of an AudioGraph . In a nutshell, an AudioGraph is a melody consisting of audio pulses that represent points on thegraph of a function. Those points represent values of y as a function of x between two limits on x.

Two different AudioGraph programs were presented in earlier modules. Each was specifically designed for a particular function. One program produced anAudioGraph of a square wave. The other produced an AudioGraph of a sinusoid.

A general purpose AudioGraph program

This module expands on that concept and develops a general purpose program named MusicComposer10 that can produce an AudioGraph for virtually any single-valued function of the independent variable x for which the values of y can be encapsulated ina simple text file. Several examples are provided above . (By single-valued function in this context, I mean a function where, for every value of x within the range ofinterest, one and only one finite value exists for y.)

Where do the text files come from ?

The program doesn't know and doesn't care where the values in the text file originate. For example, they could represent the temperature in your dorm room takenmanually every hour for 36 hours and entered into a text file using a simple text editor program. On the other hand, they could be produced by acomputer program that is designed to evaluate a specific function and to write the results into an output text file as was the case for Sinc01 .
