[Libav-user] wav VS raw

[ReSearchIT Eng]

 Don't know what it means by top-post, just replying from gmail interface.

 "-f amr -acodec libvo..." -> Itried to remove, but  is a must to keep
them, it does not work without both of them. (adding only -f amr, it
defaults to amrb instead of amrwb; adding only -acodec lib.. -> gives error
it does not know the format)

The commands I used with minumum params (besides log level) were:
./ffmpeg.exe -loglevel debug -y -i 684.wav -ab 23850 -ar 16000 -f amr
-acodec libvo_amrwbenc 640bytes_fromwav_even_less_details.awb
>640bytes_fromwav_even_less_details.awb.report 2>&1

 ./ffmpeg.exe -loglevel debug -y -f s16le -ar 16000 -i 640.raw -ab 23850 -f
amr -acodec libvo_amrwbenc 640bytes_fromrRaw_min_details.awb
>640bytes_fromrRaw_min_details.awb.report 2>&1

On  https://drive.google.com/folderview?id=0B1BAL1iQSc-tN3l0Y2RzdjBvbG8 has:
The full output reports (*.txt) (~5kb each).
the reports for both cases
the input files (wav and raw)
the output files (*.awb)
as well as 2 pics from beyond compare:

Thanks again,
