Joining two wave files

[Luciano de Souza <luchyanus@...>]

Hi listers,

Is there a way to join to wave files into a single one? I prefered to do 
it in Lua in order to keep the code multiplatform, but if it's not 
possible, how to do it in Linux?

wave.join('file1.wav', 'file2.wav', file3.wav)

The desirable result is that file3.wav is the concatenation of file1 and 
file2, being file1 the first and file2 the last sound.
