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
