FAAC(1)			   Free	Advanced Audio Coder		       FAAC(1)

NAME
       faac - open source MPEG-4 and MPEG-2 AAC	encoder

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

       <infiles> and/or	<outfile> can be "-", which means stdin/stdout.

DESCRIPTION
       FAAC  is	 an  open source MPEG-4	and MPEG-2 AAC encoder,	it is licensed
       under the LGPL license.	Note that the quality of FAAC is not up	to par
       with the	currently best AAC encoders available.

FEATURES
       * Portable

       * Fast

       * LC, Main, LTP support

       * DRM support through DreaM (optional)

HELP OPTIONS
       -h     Short help on using FAAC

       -H     Description of all options for FAAC

       --license
	      License terms for	FAAC.

       --help-qual
	      Quality-related options

       --help-io
	      Input/output options

       --help-mp4
	      MP4 specific options Quality-related options

       --help-advanced
	      Advanced options,	only for testing purposes

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  in-
	      put  file;  you can use *.aac, *.mp4, *.m4a or *.m4b as file ex-
	      tension, 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  en-
	      abling  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. with-
	      out any headers).	 Not advised!!!, RAW AAC files are practically
	      useless!!!

       -P     Raw  PCM input mode (default 44100Hz 16bit stereo).  Raw PCM in-
	      put 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:  bi-
	      gendian).

       -I <C[,LFE]>
	      Input  channel  config, default is 3,4 (Center third, LF fourth)
	      Input multichannel configuration (default: 3,4 which means  Cen-
	      ter 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 al-
	      ready).

       --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).
