"-" as infile means stdin.

-d <dirname> Output directory, default is cwd
-a, --abr <bitrate> AAC ABR mode / bitrate
-V, --tvbr <n> AAC True VBR mode / quality [0-127]
-v, --cvbr <bitrate> AAC Constrained VBR mode / bitrate
-c, --cbr <bitrate> AAC CBR mode / bitrate
--he HE AAC mode (Can't use TVBR)

-q, --quality <n> AAC encoding Quality [0-2]
-r, --rate <option> Sample rate option (AAC only)

auto: Let QuickTime choose the optimal one
<number>: Literal rate in Hz
-s, --silent Don't be verbose
-n, --nice Give lower process priority
--downmix <mono|stereo> Downmix to mono/stereo
--no-optimize Don't optimize MP4 container file after encoding
--adts ADTS(raw AAC)output, instead of m4a(AAC only)
--ignorelength Assume WAV input and ignore the data chunk length
-R, --raw Raw PCM input
-S, --stat Save bitrate statistics into file
Options for single input mode only:
-o <filename> Output filename
Options for Raw PCM input only:
--raw-channels <n> Number of channels, default 2
--raw-rate <n> Sample rate, default 44100
--raw-format <str> Sample format, default S16L
Sample format spec:
1st char: S(igned) | U(nsigned) | F(loat)
2nd part: Bitwidth
Last part: L(ittle Endian) | B(ig Endian)
Cases are ignored. u8b is OK.
Tagging options(single input only):
--title <string>
--artist <string>
--band <string>
--album <string>
--grouping <string>
--composer <string>
