Hi,<br><br>I have downloaded the latest stable version <b>1.0.2 opus audio
codec</b> from the following link:<br><a href="http://www.opus-codec.org/downloads/">http://www.opus-codec.org/downloads/</a><br><br><b>Details
of OS & CPU:</b><br>OS : Microsoft Windows XP<br>CPU : intel core 2 Duo
cpu<br><br>I am using Microsoft visual C++ 2010 Express to build the codec
(opus.vcxproj available in the package downloaded). I am able to build it &
could generate the application opus_demo.exe. <br><br>With this executable, I
tried to encode 'input_48k.wav" file with the below command &
"input_48k.opus" file got generated.Please check the attached folder which
contains input file,encoded file& decoded file.<br><br><b>Encoder command
line : opus_demo -e audio 48000 2 94840 -cbr input_48k.wav
input_48k.opus</b><br><br>Similarly, I tried to decode "input_48k.opus" file
with the below command line. I am getting noisy output here.<br><b><br>Decoder
command line : opus_demo -d 48000 2 input_48k.opus
input_48k_decoded.wav<br></b><br><br><b>Experiments done:<br></b><br>I have
downloaded opus tools <a href="https://ftp.mozilla.org/pub/mozilla.org/opus/win32/opus-tools-0.1.6-win32.zip">opus-tools-0.1.6-win32.zip</a>
from <a href="http://www.opus-codec.org/downloads/">http://www.opus-codec.org/downloads/</a>
link.<br>With the available executables in this folder (opusenc.exe ,
opusdec.exe) , I am able to get noise free output.<br><br><b>Case 1: checking
the codec's encoder:</b><br><br>With the codec's encoded "<b>input_48k.opus</b>"
file as input,I have run Opus tool's decoder (which is working fine).<br>With
this, I am getting error message like "This doesn't look like a Opus
file".<br><br><b>Case 2:</b> <b>checking the codec's decoder:</b><br><br>With
the tools's generated encoded output (opus file which is proper), I have run
codec's decoder to generate the decoded output.<br>It is not generating any
output(0 bytes output).<br><br>Can you please help me here.<br><br>Regards,<br>Deepthi<br>
