Hey Erich,

 	Thanks for the reply. However, I tried it without the ‘speed’ call and still got the same noise  But I think I know what the problem may be now.  I just noticed this warning:

sox WARN pad: Input audio too short; pads not applied: 1

So I guess the sound is too short for padding to work?  I’m not sure why the length of the sound would matter for padding.  And it *is* making the sound the length I specify, so ‘pad’ is doing something.  That is kind of weird.  

Bob
