	  <title>DESCRIPTION</title>

	  <para><command>flac</command> is a command-line tool for
             encoding, decoding, testing and analyzing FLAC streams.
          </para>

	  <para>This manual page was originally written for the &debian;
	    distribution because the original program did not have a
	    manual page.</para>

		</term>
		<listitem>
		  <para>Do not print anything of any kind,

		    code will be the only way to determine
		    successful completion.</para>
		</listitem>
	      </varlistentry>

	      <varlistentry>
		<term><option>-f</option>, <option>--force</option>
		</term>
		<listitem>
		  <para>Force overwriting of output files.  By default,
		    flac warns that the output file already exists and
		    continues to the next file.</para>
		</listitem>
	      </varlistentry>

	      <varlistentry>
		<term><option>-o</option> <replaceable>filename</replaceable>, <option>--output-name</option>=<replaceable>filename</replaceable></term>
		<listitem>
		  <para>Force the output file name (usually flac just
		    changes the extension).  May only be used when
		    encoding a single file.  May not be used in
		    conjunction with --output-prefix.</para>
		</listitem>
	      </varlistentry>

	      <varlistentry>
		<term><option>--output-prefix</option>=<replaceable>string</replaceable></term>
		<listitem>
		  <para>Prefix each output file name with the given
		    string.  This can be useful for encoding or decoding
		    files to a different directory.  Make sure if your
		    string is a path name that it ends with a trailing
		    `/' (slash).</para>
		</listitem>
	      </varlistentry>

	      <varlistentry>
		<term><option>--delete-input-file</option>
		</term>
		<listitem>
		  <para>Automatically delete the input file after a
		    successful encode or decode.  If there was an
		    error (including a verify error) the input file
		    is left intact.</para>
		</listitem>
	      </varlistentry>

	      <varlistentry>
		<term><option>--skip</option>={<replaceable>#</replaceable>|<replaceable>mm:ss.ss</replaceable>}</term>
		<listitem>
		  <para>Skip over the first number of samples of the input.
		    This works for both encoding and decoding, but not
		    testing.  The alternative form mm:ss.ss can be used
		    to specify minutes, seconds, and fractions of a
		    second.</para>
		</listitem>
	      </varlistentry>

	      <varlistentry>
		<term><option>--until</option>={<replaceable>#</replaceable>|[<replaceable>+</replaceable>|<replaceable>-</replaceable>]<replaceable>mm:ss.ss</replaceable>}</term>
		<listitem>
		  <para>Stop at the given sample number for each input file.
		    This works for both encoding and decoding, but not testing.
		    The given sample number is not included in the decoded
		    output.  The alternative form mm:ss.ss can be used to
		    specify minutes, seconds, and fractions of a second.  If a
		    `+' (plus) sign is at the beginning, the --until point is
		    relative to the --skip point.  If a `-' (minus) sign is at
		    the beginning, the --until point is relative to end of the
		    audio.</para>
		</listitem>
	      </varlistentry>

	      <varlistentry>
		<term><option>--ogg</option></term>

		<listitem>
		  <para>When encoding, generate Ogg FLAC output instead
		    of native FLAC.  Ogg FLAC streams are FLAC streams
		    wrapped in an Ogg transport layer.  The resulting
		    file should have an '.ogg' extension and will still
		    be decodable by flac.</para>
		  <para>When decoding, force the input to be treated as
		    Ogg FLAC.  This is useful when piping input from
		    stdin or when the filename does not end in '.ogg'.</para>
		</listitem>
	      </varlistentry>

	      <varlistentry>
		<term><option>--serial-number</option>=<replaceable>#</replaceable></term>

		<listitem>
		  <para>When used with --ogg, specifies the serial number to
		    use for the first Ogg FLAC stream, which is then
		    incremented for each additional stream.  When encoding and
		    no serial number is given, flac uses a random number for
		    the first stream, then increments it for each additional
		    stream.  When decoding and no number is given, flac uses
		    the serial number of the first page.</para>

	    <title>Analysis Options</title>

	    <variablelist>
	      <varlistentry>
		<term><option>--residual-text</option>
		</term>
		<listitem>
		  <para>Includes the residual signal in the analysis
		    file.  This will make the file very big, much
		    larger than even the decoded file.</para>
		</listitem>
	      </varlistentry>

	      <varlistentry>
		<term><option>--residual-gnuplot</option>
		</term>
		<listitem>
		  <para>Generates a gnuplot file for every subframe;
		    each file will contain the residual distribution
		    of the subframe.  This will create a lot of
		    files.</para>
		</listitem>
	      </varlistentry>

	    <title>Decoding Options</title>

	    <variablelist>
	      <varlistentry>
		<term><option>--cue=[<replaceable>#.#</replaceable>][-[<replaceable>#.#</replaceable>]]</option></term>
		<listitem>
		  <para>Set the beginning and ending cuepoints to decode.
		    The optional first #.# is the track and index point at
		    which decoding will start; the default is the beginning
		    of the stream.  The optional second #.# is the track
		    and index point at which decoding will end; the default
		    is the end of the stream.  If the cuepoint does not
		    exist, the closest one before it (for the start point)
		    or after it (for the end point) will be used.  If those
		    don't exist, the start of the stream (for the start
		    point) or end of the stream (for the end point) will be
		    used.  The cuepoints are merely translated into sample
		    numbers then used as --skip and --until.</para>
		</listitem>
	      </varlistentry>

	      <varlistentry>
		<term><option>-F</option>, <option>--decode-through-errors</option>
		</term>
		<listitem>
		  <para>By default flac stops decoding with an error
		    and removes the partially decoded file if it
		    encounters a bitstream error.  With -F, errors are
		    still printed but flac will continue decoding to
		    completion.  Note that errors may cause the decoded
		    audio to be missing some samples or have silent
		    sections.</para>

		</listitem>
	      </varlistentry>

	      <varlistentry>
		<term><option>--lax</option></term>

		<listitem>
		  <para>Allow encoder to generate non-Subset
		    files.  The resulting FLAC file may not be
		    streamable or might have trouble being played
		    in all players (especially hardware devices),
		    so you should only use this option in
		    combination with custom encoding options meant
		    for archival.</para>
		</listitem>
	      </varlistentry>

	      <varlistentry>
		<term><option>--replay-gain</option></term>

		<listitem>
		  <para>Calculate ReplayGain values and store in
		    Vorbis comments, similar to vorbisgain.  Title
		    gains/peaks will be computed for each input
		    file, and an album gain/peak will be computed
		    for all files.  All input files must have the
		    same resolution, sample rate, and number of
		    channels.  Only mono and stereo files are
		    allowed, and the sample rate must be one of
		    8, 11.025, 12, 16, 22.05, 24, 32, 44.1, or 48
		    kHz.  Also note that this option may leave a
		    few extra bytes in a PADDING block as the exact
		    size of the tags is not known until all files
		    are processed.  Note that this option cannot be
		    used when encoding to standard output (stdout).

		<term><option>--cuesheet</option>=<replaceable>filename</replaceable></term>

		<listitem>
		  <para>Import the given cuesheet file and store it in a
		    CUESHEET metadata block.  This option may only be used
		    when encoding a single file.  A seekpoint will be added
		    for each index point in the cuesheet to the SEEKTABLE
		    unless --no-cued-seekpoints is specified.</para>

	      <varlistentry>
		<term><option>--sector-align</option></term>
