One would expect 

 Display ["hello.wav", Play [Sin[2*Pi*440*t], {t,0,1}], "WAV" ]

to make a wav file.
It does not. At least in my 3.0 version.
Is there some package or another tool to make something like this with sound ?

Thank you

: What do you define as "does not work"?  An example of a channel is a 
: pipe, and this surely works on Unix versions of Mathematica.

: If you have either PBMPlus or netPBM installed on your system, 
: try something like this:

: Plot[Sin[x], {x,0,2Pi}, 
:   DisplayFunction :> (
:       Display["!pnmsmooth | ppmtogif > testme.gif", #, "PBM"]&)]

: The plot is fed into psrender, which converts the graphic to a 
: portable bitmap.  It is then piped through two of the filter tools
: from the above toolkits to create a somewhat blurred gif.

: I believe that you can also use an OutputStream[] as a channel.
