...pcm out.pcm For opusenc/dec: opusenc --raw --raw-chan 1 bitrate 64 -cvbr --framesize 10 in.pcm in.opus opusdec in.opus out.pcm the PEAQ value for opus_demo is -0.152 and for opus-tools is -0.449 Should I expect the same quality or are opus_demo and opusenc/dec different by definition? Thanks, Quilino

...opus library (also using libogg 1.3.1). When I execute opus-demo it says it uses libopus 1.1-beta; when I execute opusenc,it says "Encoding using libopus-1.1-beta". Should I assume that my installation is correct and that both utilities use my locally intalled version of libopus?

...same libopus (opusenc could be using the system libopus 1.0.x while opus_demo is from git). In the end, the quality should be almost the same, but the files won't be identical due to minor differences in the way the first and last frame are handled.
