TLDR
Encode to Opus
$ opusenc [input.wav] [output.opus]
Set bitrate$ opusenc --bitrate [128] [input.wav] [output.opus]
Set quality$ opusenc --vbr --comp [10] [input.wav] [output.opus]
Add metadata$ opusenc --title "[title]" --artist "[artist]" [input.wav] [output.opus]
Encode from pipe$ ffmpeg -i [input] -f wav - | opusenc - [output.opus]
SYNOPSIS
opusenc [options] input output
DESCRIPTION
opusenc encodes raw or container audio (WAV, AIFF, FLAC, or raw PCM) to the Opus codec inside an Ogg container. Opus is a low-latency, royalty-free codec well suited to both music and speech at bitrates from 6 to 510 kbit/s.By default opusenc uses VBR at complexity 10, which gives the best quality for the size at the cost of CPU time. Reading from `-` lets you pipe from `ffmpeg`, `sox`, or similar tools.
PARAMETERS
INPUT
Input audio file.OUTPUT
Output Opus file.--bitrate KBPS
Target bitrate in kbit/s. Default is 64 for mono, 96 for stereo.--vbr
Use variable bitrate (default).--cvbr
Use constrained variable bitrate.--hard-cbr
Use hard constant bitrate.--comp LEVEL
Encoding complexity, 0 (fast) to 10 (slowest, best quality). Default 10.--framesize MS
Frame size in ms (2.5, 5, 10, 20, 40, 60). Default 20.--music / --speech
Tune the encoder for music or for speech.--downmix-mono / --downmix-stereo
Force mono or stereo output.--title TITLE, --artist NAME, --album NAME
Set Vorbis-style metadata tags.--raw, --raw-rate HZ, --raw-chan N
Treat input as headerless PCM with the given sample rate and channel count.--help

sudo pacman -S opus-tools
sudo apk add opus-tools
sudo zypper install opus-tools

nix profile install nixpkgs#opus-tools
CAVEATS
Shipped as part of opus-tools. Input must be WAV, AIFF, FLAC, or raw PCM; MP3 and other lossy formats should be decoded first (typically via ffmpeg). Opus is lossy: re-encoding from another lossy source compounds artifacts.
HISTORY
opusenc was created for encoding audio to the Opus codec format.
