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).
