oggenc
reads audio data in either raw, WAV, or AIFF format and encodes it into an
Ogg Vorbis stream. If the input file "-" is specified, audio data is
read from
stdin
and the Vorbis stream is written to
stdout
unless the
-o
option is used to redirect 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).
OPTIONS
-h, --help
Show command help.
-r, --raw
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 this.
-B n, --raw-bits=n
Sets raw input sample size in bits. Default is 16.
-C n, --raw-chan=n
Sets raw input number of channels. Default is 2.
-R n, --raw-rate=n
Sets raw input samplerate. Default is 44100.
-Q, --quiet
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).
-q n, --quality=n
Sets encoding quality to n, between 0 (low) and 10 (high). This is the default mode of operation.
-s, --serial
Forces a specific serial number in the output stream. This is primarily useful for testing.
-o output_file, --output=output_file
Write the Ogg Vorbis stream to
output_file (only valid if a single input file is specified)
-n pattern, --names=pattern
Produce filenames as this string, with %a, %t, %l, %G replaced by artist,
title, album respectively (see below for specifying these). Also, %%
gives a literal %.
-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.
-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.
EXAMPLES
Simplest version. Produces output as somefile.ogg:
oggenc somefile.wav
Specifying an output filename:
oggenc somefile.wav -o out.ogg
Specifying a high-quality encoding averaging 256 kbps.
oggenc infile.wav -b 256 out.ogg
Specifying a maximum and average bitrate.
oggenc infile.wav -b 128 -M 160 out.ogg
Specifying quality rather than bitrate (to a very high quality mode)
oggenc infile.wav -q 9 out.ogg
Adding some info about the track:
oggenc somefile.wav -t "The track title" -a "artist who performed 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.):
Options -m, -M, and -q for for flexible bitrate/quality selection exist, but are not
implemented in the vorbis encoder, and so are not documented here yet.
