This pcap file in cloudshark was captured during a voip mobile app (audio) conversation. https://www.cloudshark.org/captures/8fef0eaa85f4
As we can see, Opus is used as codec. In wireshark, I analyzed the RTP stream, saved as raw file.
Then I downloaded opus encode/decoder tool from : http://www.opus-codec.org/downloads/
I encoded the raw file as : "encode.exe --bitrate 16 --raw myrawfile.raw output.opus"
Then Tried to play opus file in audacity. What I can get is only the noise. I tried by decoding the opus file into wav and play again. Still no luck.
Could you please suggest me where have I gone wrong ?

You want to go the other way, decode from opus to wav.
