NAME

       opusdec - decode audio in Opus format to Wave or raw PCM

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 ]

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.

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

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

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.
