Hi I am using opus_demo binary to test 48KHz Stereo file, i used below arguments to encode and decode. ./opus_demo -e audio 48000 2 48k_stereo.pcm stereo.opus ./opus_demo -d 48000 2 stereo.opus stereo.pcm After decoding i found that both left and right channels are identical, even input stereo file channels are differential in gain. 1. Is this the expected behavior of OPUS CODEC, if yes then encoding and decoding stereo file with no of channels=2 improves the quality of voice? -- Thanks & Regards Vittalprasad B R 8722397247

That probably explains why the quality's really bad.
