Regarding Test vectors - Thenral p - Dec 5 9:23:00 2001

Hi All, I have been working on a floating point version for the G.729 fixed point code.The test vector I have been using is the "speech.in" file supplied with the G.729 code.I have been scaling it by 32767 and using it, but is there some other test vector for using with the floating point version. When I use it without scaling there seems to be lots of overflow problems. There also seems to be no vector supplied with Annexe C(floating point version of G.729).Can anyone suggest a method of testing the code or what should the scaling factor of speech.in be? Thanks a lot. Thenral |
