Hi Peter,
this is from the [EMAIL PROTECTED] mailing list:

Hi Johan,
one possibility is to use one SourceDataLine for all samples of the same
track and to fill the gaps between the samples with an exactly
calculated number of zero-value frames. Attached is a class that may
help you. Using this class you can insert silence the following way:
AudioFormat format = ...;
AudioChannel channel = new AudioChannel(format);
channel.start();
// add AudioInputStreams representing you samples
AudioInputStream ais = ...;
channel.addAudioInputStream(ais);
// now insert 10 frames of silence
byte[] abSilence = new byte[10 * format.getFrameSize()];
for (int i = 0; i < abSilence.length; i++)
{
abSilence[i] = 0;
}
ByteArrayInputStream bais = new ByteArrayInputStream(abSilence);
AudioInputStream ais = new AudioInputStream(bais, format, 10);
channel.addAudioInputStream(ais);

Note that since AudioChannel class is taken directely out of an
application, you have to comment out some things to make it work. There
seems to be general interest in such a class, therefore there soon will
be a cleaned-up version of this class on the JavaSound Examples page at
http://rupert.informatik.uni-stuttgart.de/~pfistere/jsexamples/.
If you have further questions, be free to contact me.
