       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


       -h, --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

       -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.

       --raw-endianness n
              Sets raw mode endianness to big endian (1) or little endian (0).
              Default is little endian.

       -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).

              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 n
              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.

       --advanced-encode-option optionname=value
              Sets an advanced option. See the Advanced  Options  section  for

       -s, --serial
              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
              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.  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.


       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-
       rently documented.

              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:
              oggenc somefile.wav

       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).
