+.SH QUALITY-RELATED OPTIONS
+.TP
+.BR -q\ <\fIquality\fP>
+Set encoding quality. Set default variable bitrate (VBR) quality level in percent.
+(default: 100, averages at approx. 120 kbps VBR for a normal stereo input file with 16 bit and 44.1 kHz sample rate; max value 2000, min 10).
+.TP
+.BR -b\ <\fIbitrate\fP>
+Set average bitrate (ABR) to approximately <bitrate> kbps.
+(max. value 152 kbps/stereo with a 16 kHz cutoff, can be raised with a higher -c setting).
+.TP
+.BR -c\ <\fIfreq\fP>
+Set the bandwidth in Hz. (default 0.42 of sampling freq)
+
+.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 set
+automatically to ADTS or MP4).
+.TP
+.BR -
+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.
+.TP
+.BR -v\ <\fIvebose\fP>
+Verbosity level (-v0 is  quiet mode)
+.TP
+.BR -r
 Use RAW AAC output file.
+Generate raw AAC bitstream (i.e. without any headers).
+Not advised!!!, RAW AAC files are practically useless!!!
 .TP
-.BR \-P
-Raw PCM input mode (default: 44100Hz 16bit stereo).
+.BR -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).
 .TP

+.BR -I\ <\fIC[,LFE]\fP>
+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).
 .TP
