NAME

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

SYNOPSIS

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

DESCRIPTION

       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.

OPTIONS

       -h, --help
              Print help message

       -V, --version
              Display version information

       --quiet
              Suppresses program output

       --rate
              Force decoding at sampling rate n Hz

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

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

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

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

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

       --save-range
              Saves 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 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

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

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.
