Anthony Appleyard had the answer to indents in another thread. Use the pre pre HTML tags around your code in the post. (You'll have to imagine the angle brackets in that last sentence because the post will eat anything in angle brackets even wrapped in pre pre. I don't know what's up with that, but I quess it means you'll have to avoid angle bracket pairs in your code. Still it's an improvement.) For instance (quoting but formatting from above using tags),

    if SoundLen < 1024:
       exit
    else:
                #convert buf to array of float
       floatbuf = Numeric.array(buf,"Float")

QED. Cheers for Anthony!
