       opusdec - decode audio from Opus format to WAV (or simple audio output)


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


       opusdec decodes Opus files into PCM Wave (uncompressed) files.

       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.

              Suppresses program output

              Force decoding at sampling rate n Hz

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

              Do not dither 16-bit output

              32-bit floating-point files instead of 16-bit files

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

              Simulate n % random Opus packet loss

              Saves check values for every frame to a file


       Decode a file input.opus to output.wav
              opusdec input.opus output.wav

       Play a file input.opus and force output at 48000 regardless of the original sampling rate
       (48kHz output may be faster, due to avoiding resampling and some sound  hardware  produces
       higher quality output when run at 48kHz)
              opusdec --rate 48000 input.opus

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

       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.
