       faac - encode audio to the MPEG-2/-4 AAC format


       faac [options] [-o outfile] infiles ...


       FAAC  is  a  free  AAC  audio encoder that can compress WAV and raw PCM
       audio files.  AAC is commonly used as the primary format in  the  Apple
       iPod   and   iTunes,  although  several  other  software  and  hardware
       implementations exist that can play back AAC files such  as  FAAD2  and


   Quality-related options
       -q quality
              Set  the  default  variable  bitrate  (VBR) quantizer quality in
              percent.  Default is 100 which is approximately 120 kbps VBR for
              a  normal stereo 16-bit 44.1 kHz input.  Min value 10, max value

       -b bitrate
              Set the average bitrate (ABR) to approximately bitrate kbps.

       -c freq
              Set the bandwidth in Hz.  By default,  FAAC  will  automatically
              adapt the maximum value to the input sample rate.

   Input/Output options
       -      Use stdin as input file.

       -o outfile
              Set  the  output  file  to outfile ; you can use a dash (“-”) to
              specify stdout as the output file.

       -P     Enable raw PCM input mode.  By default, this is not enabled  and
              FAAC  expects  a  WAV file as input.  Using this option will use
              the default values for -R, -B, and -C unless otherwise modified.

       -R rate
              Set the raw PCM input sample rate to rate Hz.  Default is 44100,
              max is 96000.

       -B bitsize
              Set the raw PCM input sample size to bitsize bits.   Default  is
              16,  other  available sizes are 8, 24, and 32.  Input is assumed
              to be big endian unless otherwise specified with -X

       -X     Change raw PCM input  byte  order  from  big  endian  to  little

       -C channels
              Set the raw PCM input channel count.  Default is 2 (stereo), max
              is 33 + 1 LFE.

       -I centre[,lfe]
              Set  the  raw  PCM  input  multichannel  configuration.   centre
              specifies  which  channel is the centre channel (default 3), and
              lfe specifies which channel is the LFE channel (default 4).

       -r     Output file as raw AAC data (i.e. without ADTS headers).

   MP4-specific options
       -w     Wrap AAC data in an MP4 container.  This is enabled  by  default
              for output files with the extensions .mp4 and .m4a.

       --artist artist
              Set artist to artist

       --writer writer
              Set writer to writer

       --title title
              Set title to title

       --genre genre
              Set genre to genre

       --album album
              Set album to album

              Set compilation

       --track track
              Set track to track in the format “number/total”

       --disc disc
              Set disc to disc in the format “number/total”

       --year year
              Set year to year

       --cover-art file
              Set cover art to image in file; supported formats are GIF, JPEG,
              and PNG.

       --comment comment
              Set comment to comment

   Expert options
              Disable temporal noise shaping coding.

              Disable mid/side coding.

       --mpeg-vers version
              Set the AAC MPEG version to either 2 or 4.

       --obj-type type
              Set the AAC object type to LC (Low Complexity,  default),  Main,
              or LTP (Long Term Prediction).

       --shortctl type
              Force block type of short (1), long (2), or both (by default).


       FAAC  conforms  to  ISO/IEC  14496  (MPEG-4)  in  parts  1 (Systems), 3
       (Audio), and 14 (MPEG-4 File Format), as well as ISO/IEC 13818 (MPEG-2)
       part  7  (Advanced  Audio  Coding).   Not all audio profiles/codecs are
       supported, but the most common (LC-AAC, or Low Complexity) is supported
