opusdec: decode audio from Opus format to WAV (or simple audio output)
Command to display opusdec manual in Linux: $ man 1 opusdec
NAME
opusdec — decode audio from Opus format to WAV (or simple audio output)
SYNOPSIS
opusdec [ -hV ] [ —rate Hz ] [ —gain dB ] [ —no-dither ] [ —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 —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
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)

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.

opusdec — Man Page
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
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
Output 32-bit floating-point samples instead of 16-bit integer samples
Force including a Wave header on output (e.g. for non-wav extensions and stdout)
Simulate n % random Opus packet loss
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
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
