oggenc reads audio data in either raw, WAV, or AIFF format and encodes
it into an Ogg Vorbis stream. oggenc may also read audio data from
FLAC and Ogg FLAC files depending upon compile-time options. If the
input file "-" is specified, audio data is read from stdin and the Vor-
bis stream is written to stdout unless the -o option is used to redi-
rect the output. By default, disk files are output to Ogg Vorbis files
of the same name, with the extension changed to ".ogg". This naming
convention can be overridden by the -o option (in the case of one file)
or the -n option (in the case of several files). Finally, if none of
these are available, the output filename will be the input filename
with the extension (that part after the final dot) replaced with ogg,
so file.wav will become file.ogg

Assume input data is raw little-endian audio data with no header
information. If other options are not specified, defaults to
44.1kHz stereo 16 bit. See next three options for how to change
-B n, --raw-bits=n
Sets raw mode input sample size in bits. Default is 16.
-C n, --raw-chan=n
Sets raw mode input number of channels. Default is 2.
-R n, --raw-rate=n
Sets raw mode input samplerate. Default is 44100.
Sets raw mode endianness to big endian (1) or little endian (0).
Default is little endian.
Quiet mode. No messages are displayed.
-b n, --bitrate=n
Sets encoding to the bitrate closest to n (in kb/s).
-m n, --min-bitrate=n
Sets minimum bitrate to n (in kb/s).
-M n, --max-bitrate=n
Sets maximum bitrate to n (in kb/s).
Set bitrate management mode. This turns off the normal VBR
encoding, but allows hard or soft bitrate constraints to be
enforced by the encoder. This mode is much slower, and may also
be lower quality. It is primarily useful for creating files for
-q n, --quality=n
Sets encoding quality to n, between -1 (low) and 10 (high). This
is the default mode of operation, with a default quality level
of 3. Fractional quality levels such as 2.5 are permitted. Nor-
mal quality range is 0 - 10.
Resample input to the given sample rate (in Hz) before encoding.
Primarily useful for downsampling for lower-bitrate encoding.
Downmix input from stereo to mono (has no effect on non-stereo
streams). Useful for lower-bitrate encoding.
Sets an advanced option. See the Advanced Options section for
Forces a specific serial number in the output stream. This is
primarily useful for testing.
Prevents comments in FLAC and Ogg FLAC files from being copied
to the output Ogg Vorbis file.
-o output_file, --output=output_file
Write the Ogg Vorbis stream to output_file (only valid if a sin-
gle input file is specified)
-n pattern, --names=pattern
Produce filenames as this string, with %g, %a, %l, %n, %t, %d
replaced by genre, artist, album, track number, title, and date,
respectively (see below for specifying these). Also, %% gives a
-c comment, --comment comment
Add the string comment as an extra comment. This may be used
multiple times, and all instances will be added to each of the
input files specified. The argument should be in the form
-a artist, --artist artist
Set the artist comment field in the comments to artist.
-G genre, --genre genre
Set the genre comment field in the comments to genre.
-d date, --date date
Sets the date comment field to the given value. This should be
the date of recording.
-N n, --tracknum n
Sets the track number comment field to the given value.
-t title, --title title
Set the track title comment field to title.
-l album, --album album
Set the album comment field to album.
Note that the -a, -t, and -l options can be given multiple times. They
will be applied, one to each file, in the order given. If there are
fewer album, title, or artist comments given than there are input
files, oggenc will reuse the final one for the remaining files, and
issue a warning in the case of repeated titles.
ADVANCED ENCODER OPTIONS
Oggenc allows you to set a number of advanced encoder options using the
--advanced-encode-option option. These are intended for very advanced
users only, and should be approached with caution. They may signifi-
cantly degrade audio quality if misused. Not all these options are cur-
Set the managed bitrate window to NN seconds. The bitrate will
be forced to the specified average over a floating window of
this length. May be fractional (e.g. 3.5)
Set the lowpass frequency to NN kHz.
Simplest version. Produces output as somefile.ogg:
Specifying an output filename:
oggenc somefile.wav -o out.ogg
Specifying a high-quality encoding averaging 256 kbps (but still VBR).
oggenc infile.wav -b 256 out.ogg
Specifying a maximum and average bitrate, and enforcing these.
oggenc infile.wav --managed -b 128 -M 160 out.ogg
Specifying quality rather than bitrate (to a very high quality mode)
oggenc infile.wav -q 6 out.ogg
Downsampling and downmixing to 11 kHz mono before encoding.
oggenc --resample 11025 --downmix infile.wav -q 1 out.ogg
Adding some info about the track:
oggenc somefile.wav -t "The track title" -a "artist who per-
formed this" -l "name of album" -c "OTHERFIELD=contents of some
other field not explictly supported"
This encodes the three files, each with the same artist/album tag, but
with different title tags on each one. The string given as an argument
to -n is used to generate filenames, as shown in the section above.
This example gives filenames like "The Tea Party - Touch.ogg":
oggenc -b 192 -a "The Tea Party" -l "Triptych" -t "Touch"
track01.wav -t "Underground" track02.wav -t "Great Big Lie"
track03.wav -n "%a - %t.ogg"
Encoding from stdin, to stdout (you can also use the various tagging
options, like -t, -a, -l, etc.):

Reading type 3 wav files (floating point samples) probably doesn’t work
other than on intel (or other 32 bit, little endian machines).
