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?

Crude delay?
Hello,
What is meant by crude delay in PESQ quality testing?
And what is its tolerant limit for good quality.

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