 * Construct a sound playback object. This constructor creates an object that writes audio to a sound file. To create a new sound file, call the <i>startPlayback()</i> method. Thereafter, each call to <i>putSamples()</i> will add <i>putSamplesSize</i> many samples to the sound file. To close and save the sound file, call method <i>stopPlayback</i>.
 * @param fileName The file name to create. If the file alreadyexists, overwrite it. Valid sound file formats are WAVE (.wav), AIFF (.aif, .aiff), AU (.au). The file format to write is determined automatically from the file extension.
 * @param sampleRate Sample rate in Hz. Must be in the range: 8000to 48000.
 * @param sampleSizeInBits Number of bits per sample (valid choices are8 or 16).
 * @param channels Number of audio channels. 1 for mono, 2 forstereo, etc.
 * @param putSamplesSize Size of the array parameter of<i>putSamples()</i>. For performance reasons, the size should be chosen smaller than <i>bufferSize</i>. Typical values are 1/2 to 1/16th of <i>bufferSize</i>.
