QUALITY-RELATED OPTIONS

       -q <quality>
              Set  encoding quality. Set default variable bitrate (VBR) quality level in percent.
              max. 5000, min. 10.  default: 100, averages at approx. 120 kbps VBR  for  a  normal
              stereo input file with 16 bit and 44.1 kHz sample rate

       -b <bitrate>
              Set average bitrate (ABR) to approximately <bitrate> kbps.  max. ~500 (stereo)

       -c <freq>
              Set  the  bandwidth  in  Hz.   The  actual  frequency is adjusted to maximize upper
              spectral band usage.

INPUT/OUTPUT OPTIONS

       -o <filename>
              Set output file to X (only for one input file) only for one input file; you can use
              *.aac,  *.mp4,  *.m4a  or  *.m4b as file extension, and the file format will be set
              automatically to ADTS or MP4).

       -      Use stdin/stdout.  If you simply use a hyphen/minus sign  instead  of  a  filename,
              FAAC  can  encode directly from stdin, thus enabling piping from other applications
              and utilities. The same works for stdout as well, so FAAC can pipe  its  output  to
              other apps such as a server.

       -v <vebose>
              Verbosity level (-v0 is  quiet mode)

       -r     Use  RAW  AAC  output file.  Generate raw AAC bitstream (i.e. without any headers).
              Not advised!!!, RAW AAC files are practically useless!!!

       -P     Raw PCM input mode (default 44100Hz 16bit stereo).  Raw PCM  input  mode  (default:
              off, i.e. expecting a WAV header; necessary for input files or bitstreams without a
              header; using only -P assumes the default values for -R, -B and  -C  in  the  input
              file).

       -R <samplerate>
              Raw  PCM  input  rate.  Raw PCM input sample rate in Hz (default: 44100 Hz, max. 96
              kHz)

       -B <samplebits>
              Raw PCM input sample size (8, 16 (default), 24 or 32bits).  Raw  PCM  input  sample
              size (default: 16, also possible 8, 24, 32 bit fixed or float input).

       -C <channels>
              Raw PCM input channels.  Raw PCM input channels (default: 2, max. 33 + 1 LFE).

       -X     Raw PCM swap input bytes Raw PCM swap input bytes (default: bigendian).

       -I <C[,LFE]>
              Input  channel  config, default is 3,4 (Center third, LF fourth) Input multichannel
              configuration (default: 3,4 which means Center is third and LFE is fourth  like  in
              5.1  WAV,  so  you  only  have  to  specify  a different position of these two mono
              channels in your multichannel input files if they haven't been reordered already).

       --ignorelength
              Ignore wav length from header (useful with files over 4 GB)

       --overwrite
              Overwrite existing output file

MP4 SPECIFIC OPTIONS

       -w     Wrap AAC data in MP4 container. (default for *.mp4, *.m4a and *.m4b)

       --tag <tagname,tagvalue>
              Add named tag (iTunes '----')

       --artist <name>
              Set artist name

       --composer <name>
              Set composer name

       --title <name>
              Set title/track name

       --genre <number>
              Set genre number

       --album <name>
              Set album/performer

       --compilation
              Mark as compilation

       --track <number/total>
              Set track number

       --disc <number/total>
              Set disc number

       --year <number>
              Set year

       --cover-art <filename>
              Read cover art from file X Supported image formats are GIF, JPEG, and PNG.

       --comment <string>
              Set comment

ADVANCED OPTIONS, ONLY FOR TESTING PURPOSES

       --tns  Enable coding of TNS, temporal noise shaping.

       --no-tns
              Disable coding of TNS, temporal noise shaping.

       --no-midside
              Don't use mid/side coding.

       --mpeg-vers X
              Force AAC MPEG version, X can be 2 or 4

       --shortctl X
              Enforce block type (0 = both (default); 1 = no short; 2 = no long).
