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 re-
       altime 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	exten-
	      sions 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  -  out-
	      put.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 re-
       ject.  It also doesn't provide very helpful output  for	the  corrupted
       files it	does reject. Use opusinfo(1) for somewhat better diagnostics.
