Speex dev - May 2010 - speex encoding

I am encoding audio with quality=0 (2150 bps) and get the expected 43 
bits per packet (every 20 ms). 
However, in my limited testing I notice that the last 3 bits 
never change, seeming to indicate that the audio is fully encoded in 40 bits. 
It is important in my application that the audio is compressed as much as 
possable for transmission over a communication system. My question is, is it 
possable to strip these 3 bits off before transmission and reinsert them at the 
receiving end before decoding?

Yes, this mode has a few redundant bits (for historical reasons). You 
can always strip them as long as you put them back for decoding.
