NAME¶
opusdec - decode audio from Opus format to WAV (or simple audio output)SYNOPSIS¶
opusdec [ -hV ] [ --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¶

- --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)

EXAMPLES¶
Decode a file input.opus to output.wavopusdec input.opus output.wav
Play a file input.opus and force output at 48000 regardless of the
original sampling rate
opusdec --rate 48000 input.opus
Re-encode a high bitrate Opus file to a lower rate
opusdec --force-wav input.opus - | opusenc --bitrate 64 -

Jean-Marc Valin <jmvalin@jmvalin.ca>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.SEE ALSO¶
