[Speex-dev] Possbile to DeNoise during decode?

The Speex preprocessor works independently of the codec.  You give it 
audio data and it gives you back processed audio data.  The codec is 
not involved.  So you can use the preprocessor before encoding, after 
decoding, or whenever else you feel like it.

Since the codec will work better on less noisy input, it makes sense 
to use the denoiser before encoding.  But there's nothing forcing you 
to do it that way.
