How to add silence in front of and to the back of a WAV file

How can I add silence to the beginning and the end of a WAV file开发者_开发百科 with Java?

the length of the silence should be variable.

see this thread: Join two WAV files from Java?

If you have create a wav that is just a few seconds of silence you could combine your files together to get the required result, silence.wav + myfile.wav + silence.wav

The thread I linked to gives you the barebones code to combine wav file together. - be sure to vote up the answer in the other thread :)

Hope this helps, Eamonn
