more like:
a=SoundFile.load("test.wav");
a=a+a;
a.write("test-out.wav");

ok, but i meant something different.
more like 

buffer.edit(outbuffer_id,{dothis});

no because than it would be realtime.

not not enough

Do you mean doing things with the FFT functions?

When you say certain parts, do you mean certain frequencies?

Re: non-realtime-sound-prozessing in sc

Also... take a look at the Signal class... this may be more what you are looking for.

Re: non-realtime-sound-prozessing in sc

yes, again not realy.
beacause: it's still realtime, you cant sort a soundfile in this 
structure, you cant generate metadata.
because of the difference between sclang and the server.

a good thing would be to be able to use the language to do manipulate 
buffers on the server.

b = Buffer.read(s, "sounds/a11wlk01.wav");
c = Buffer.alloc(s,44100 * 8.0,2);
b.modify(c,{arg arr; arr.pyramid(1)});
or
c.fill(b,{arg arr; arr.pyramid(1)});

for this you would need something like sclang on the server and this 
would be asynchrone.
... or something else.

svn commits to mailing list ?


Should we have the commits ( with diffs ) sent to the dev list  
automatically ?

I don't see the need to set up a separate mailing list.

You can set up a filter in your mailer to put them in a folder if you  
like.

re: mixed line endings.  Its possible to add a hook to svn commit  
that would reject files with mixed line endings.

Once again... did you look at Signal?

Sorry, but how do you allocate a buffer inside a ugen? is that what you mean? no idea you could do that

Re: non-realtime-sound-prozessing in sc

No... I meant you can allocate memory (from the real-time pool) in  
the UGen. The original question was talking about doing manipulation  
on data in an array, which can be a pointer allocated from RTAlloc
