نام (NAME)
       opusdec - decode audio in Opus format to Wave or raw PCM


خلاصه دستور (SYNOPSIS)
       opusdec [ -hV ] [ --quiet ] [ --rate Hz ] [ --force-stereo ] [ --gain
       dB ] [ --no-dither ] [ --float ] [ --force-wav ] [ --packet-loss pct ]
       [ --save-range file ] input.opus [ output.wav ]


توضیحات (DESCRIPTION)
       opusdec decodes Opus URLs or files to uncompressed Wave or raw PCM.

       In URLs, the file , http , and https schemes are supported unless HTTP
       support was disabled at build time.

       If the input file is specified as - , then opusdec will read from
       stdin. Likewise, an output filename of - will cause output to be to
       stdout.

       If no output is specified opusdec will attempt to play the audio in
       realtime if it supports audio playback on your system.


گزینه‌ها (OPTIONS)
       -h, --help
              Show help message

       -V, --version
              Show version information

       --quiet
              Suppresses program output

       --rate n
              Force decoding at sampling rate n Hz

       --force-stereo
              Force decoding to stereo

       --gain n
              Adjust the output volume n dB, negative values make the signal
              quieter

       --no-dither
              Do not dither 16-bit output

       --float
              Output 32-bit floating-point samples instead of 16-bit integer
              samples

       --force-wav
              Force including a Wave header on output (e.g. for non-wav
              extensions and stdout)

       --packet-loss n
              Simulate n % random Opus packet loss

       --save-range file
              Save check values for every frame to a file


مثال‌ها (EXAMPLES)
       Decode a file input.opus to output.wav
              opusdec input.opus output.wav

       Play a file input.opus
              opusdec input.opus

       Re-encode a high bitrate Opus file to a lower rate
              opusdec --force-wav input.opus - | opusenc --bitrate 64 -
              output.opus

       Play an http stream http://icecast.somwhere.org:8000/stream.opus on a
       system with pulseaudio
       (press ctrl-c to quit)
              padsp opusdec http://icecast.somwhere.org:8000/stream.opus

اشکالات (BUGS)
       Opusdec does not currently reject all invalid files which it should
       reject.  It also doesn't provide very helpful output for the corrupted
       files it does reject. Use opusinfo(1) for somewhat better diagnostics.
