[Speex-dev] Combining multiple speech files into one

[Reed Hedges]

If you do decide to do things this way, decode from each of the three streams 
seperately (with different decoder states) and combine them somehow after 
decompression.  The jump from one stream to the other will sound poor, though, 
both from the cuts in the output, and also from sending discontinous input to 
the decoder(s).
