[Speex-dev] NOP pattern - how to make SPEEX packets bigger?

[Tomasz Pyra]

How can I add some size to SPEEX encoded packets without affecting 
decoding results?

I need it to fit smaller (due to VAD) packets in CBR acm-wav file.

i.e. I have 10 bytes packet with 0.02s of silence (only background noice 
without speech).
I need to fit it in 16kbps CBR wav file, so I need to put 30 additional 
bytes to this packets, but decoder should still decode only 0.02s of 
background noice.
