Examples of jm.audio.io.SampleOut

jm.audio.io.SampleOut
The SampleOut class is responsible for writing sample data to disk. It combines all notes into a single Random Access File based on each notes start time. The output of samples into this file is in 32 bit floating point format and a maximum amplitude for this file is calculated on the fly and storied by this class for easy normalisation when being rewritten to a standard Audio File Format.

NOTE: One important thing to note about the class is that all the notes of the score are written to the same file. Therefore everytime this class is called for each new note the information is continually written to the same temporary file often combining new data with existing data.

The SampleOut class only excepts a Single Audio Object as input and should therefore have all Audio Streams combined before being passed to the SampleOut. @author Andrew Sorensen @version 1.0, Sun Feb 25 18:42:42 2001
