This is a general purpose AudioGraph program that reads an input text filecontaining numeric values for y as a function of equally spaced values for x
and produces an output melody that represents a graph of that data. The valuesfor y are read as a comma-delimited list of values and are treated as type
double. The name of the text file is input as a command-line parameter.Additional details will be found in the class named AudioGraph01.
This program requires the following classes:AudioGraph01
AudioSignalGenerator02AudioPlayOrFile01
AudioFormatParameters01The sound can be played immediately or can be saved in an audio file of
type AU for playback later. You should be able to play the audio file with anystandard media player that can handle the AU file type
Tested using JDK 1.8 under Win 7.******************************************************************************/
public class MusicComposer10{//Instantiate an object containing audio format parameters with predefined
// values. They may be modified by the signal generator at runtime. Values// allowed by Java SDK 1.4.1 are shown in comments in the class definition.
AudioFormatParameters01 audioParams = new AudioFormatParameters01();//A buffer to hold the audio data that will be played or filed.byte[] melody;//A place to store the incoming args array.String[] args;//-------------------------------------------------------------------------//
//Command-line parameter (three parameters required)//0 - If "play", the sound will be played immediately. Otherwise, the string// will be used as a filename for an audio file of type AU. In the latter
// case, it must be a string that would be valid as a file name for the// operating system in use.
//1 - Output pulses per second//2 - Input file name
