Thank you very much for your immediate attention! I've exported my wav files to raw files before encoding and the click is now gone. That sure beats discarding the last packet, which was the workaround "solution" I was going to implement...

The problem doesn't occur with the equivalent raw file (which I used for testing). It's probably really stupid anyway.

If you have a couple minutes, it probably wouldn't be hard to see where the bug is (I just don't have time this week). It would have to do with the granulepos computation in speexenc.

I am currently pressed for time, but I will try to take a look at it.
