[Freeswitch-users] sox L16 to G711, inconsistent results

[Stanislav Sinyagin]

In order to utilize mod_native_file, I converted the original L16
8000Hz audio into G711 with sox:

sox ${SRCFILE} -t raw -r 8k -b 8 -c 1 -e u-law ${DSTDIR}/${BASENAME}.PCMU

I just discovered that if I do this command twice and compare
resulting files, they differ. They also differ if I take 44100Hz
source audio.

Anyone got a clue what's going on?

FreeSWITCH is always producing the same bitstream when converting L16 to G711.
