NAME
oggenc - encode audio into the Ogg Vorbis format

SYNOPSIS
oggenc [ -hrQ ] [ -b nominal bitrate ] [ -o output_file ] [ -n pattern ] [ -c extra_comment ] [ -a artist ] [ -t title ] [ -l album ] input_files ...

DESCRIPTION
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).

-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 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.

-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

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.):
    oggenc -

BUGS
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.
