Speex dev - Jul 2007 - Re: Crude delay?

This is regarding the speexdec.c of the latest beta2 version.
After decoding a frame, for packet_no =1, a new_frame_size and
frame_offset are calculated and the number of decoded bytes
writting onto a file depends on them. Why are they calculated?
What happens if i directly write all the 320 shorts I get after
decodong onto a file?

I think it's just the delay it found between the input and output. In
any case, you shouldn't pay attention to it (unless you get a very large
value, in which case it can mean a bug in how you generate the files).

You'll just get a delay that corresponds to the lookahead of Speex. No
big deal.

Hello,
 In the latest version(beat2), if I define FIXED in encoder,
i beleive that the code works in fixed point.
But when I define FIXED for decoder, I get build errors.
Whether decoder supports FIXED?
