Dear Rudy, thanks very much, the idea of named pipe is great! Actually it is not possible to implement it with vsound, because when you tell him to write a file it first writes out a AU file and then tries to convert it to a WAV. (I think, though, that it may be possible to use SOX for converting the AU file into wav and feed it to LAME afterwards, but one would have to modify the vsound script in order to know the vsound.dataxxx name in advance).
Anyhow, I succedeed in using mplayer to do the job. Mplayer is able to directly write out a WAV file, so I have it write it to the named pipe. If anybody is interested, I can post an example script.
