.TH FAAC 1 "2017-08-16" "1.29.5" "Free Advanced Audio Coder" .SH NAMEfaac \- open source MPEG-4 and MPEG-2 AAC encoder .SH SYNOPSIS.B faac.RI [ options ].RI [\-o\  outfile ].I infiles.RI ....PP.RI < infiles >and/or.RI < outfile >can be "\-", which means stdin/stdout. .SH DESCRIPTION.B FAACis an open source MPEG-4 and MPEG-2 AAC encoder, it is licensed under the LGPL license.Note that the quality of .B FAACis not up to par with the currently best AAC encoders available. .SH FEATURES.TP* Portable.TP* Fast.TP* LC, Main, LTP support.TP* DRM support through DreaM (optional) .SH HELP OPTIONS.TP.BR -hShort help on using FAAC.TP.BR -HDescription of all options for FAAC.TP.BR --licenseLicense terms for FAAC..TP.BR --help-qualQuality-related options.TP.BR --help-ioInput/output options.TP.BR --help-mp4MP4 specific optionsQuality-related options.TP.BR --help-advancedAdvanced options, only for testing purposes .SH QUALITY-RELATED OPTIONS.TP.BR -q\ <\fIquality\fP>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 normalstereo input file with 16 bit and 44.1 kHz sample rate.TP.BR -b\ <\fIbitrate\fP>Set average bitrate (ABR) to approximately <bitrate> kbps.max. ~500 (stereo).TP.BR -c\ <\fIfreq\fP>Set the bandwidth in Hz.The actual frequency is adjusted to maximize upper spectral band usage..SH INPUT/OUTPUT OPTIONS.TP.BR -o\ <\fIfilename\fP>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 setautomatically to ADTS or MP4)..TP.BR -Use stdin/stdout.If you simply use a hyphen/minus sign insteadof a filename, FAAC can encode directly from stdin,thus enabling piping from other applications and utilities. Thesame works for stdout as well, so FAAC can pipe its output toother apps such as a server..TP.BR -v\ <\fIvebose\fP>Verbosity level (-v0 is  quiet mode).TP.BR -rUse RAW AAC output file.Generate raw AAC bitstream (i.e. without any headers).Not advised!!!, RAW AAC files are practically useless!!!.TP.BR -PRaw 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; usingonly -P assumes the default values for -R, -B and -C in theinput file)..TP.BR -R\ <\fIsamplerate\fP>Raw PCM input rate.Raw PCM input sample rate in Hz (default: 44100 Hz, max. 96 kHz).TP.BR -B\ <\fIsamplebits\fP>Raw PCM input sample size (8, 16 (default), 24 or 32bits).Raw PCM input sample size (default: 16, also possible 8, 24, 32bit fixed or float input)..TP.BR -C\ <\fIchannels\fP>Raw PCM input channels.Raw PCM input channels (default: 2, max. 33 + 1 LFE)..TP.BR -XRaw PCM swap input bytesRaw PCM swap input bytes (default: bigendian)..TP.BR -I\ <\fIC[,LFE]\fP>Input channel config, default is 3,4 (Center third, LF fourth)Input multichannel configuration (default: 3,4 which meansCenter is third and LFE is fourth like in 5.1 WAV, so you onlyhave to specify a different position of these two mono channelsin your multichannel input files if they haven't been reorderedalready)..TP.BR --ignorelengthIgnore wav length from header (useful with files over 4 GB).TP.BR --overwriteOverwrite existing output file.SH MP4 SPECIFIC OPTIONS.TP.BR -wWrap AAC data in MP4 container. (default for *.mp4, *.m4a and*.m4b).TP.BR --tag\ <\fItagname,tagvalue\fP>Add named tag (iTunes '----').TP.BR --artist\ <\fIname\fP>Set artist name.TP.BR --composer\ <\fIname\fP>Set composer name.TP.BR --title\ <\fIname\fP>Set title/track name.TP.BR --genre\ <\fInumber\fP>Set genre number.TP.BR --album\ <\fIname\fP>Set album/performer.TP.BR --compilationMark as compilation.TP.BR --track\ <\fInumber/total\fP>Set track number.TP.BR --disc\ <\fInumber/total\fP>Set disc number.TP.BR --year\ <\fInumber\fP>Set year.TP.BR --cover-art\ <\fIfilename\fP>Read cover art from file XSupported image formats are GIF, JPEG, and PNG..TP.BR --comment\ <\fIstring\fP>Set comment.SH ADVANCED OPTIONS, ONLY FOR TESTING PURPOSES.TP.BR --tnsEnable coding of TNS, temporal noise shaping..TP.BR --no-tnsDisable coding of TNS, temporal noise shaping..TP.BR --no-midsideDon't use mid/side coding..TP.BR --mpeg-vers\ \fIX\fPForce AAC MPEG version, X can be 2 or 4.TP.BR --shortctl\ \fIX\fPEnforce block type (0 = both (default); 1 = no short; 2 = no long)..SH AUTHORS.B FAACwas written by M.
