HE-AAC : how to turn an album into 22 MB of data

[ron999]

Hi
There's a stand-alone fdkaac encoder available from here ---> https://github.com/nu774/fdkaac

Use fdkaac -h to show the options.

Examples of use.

CBR
For AAC-LC, like this:-
(Format profile : LC)

fdkaac -b 128k -o foo.m4a foo.wav

For AAC-HE, like this:-
(Format profile : HE-AAC / LC)

fdkaac -p 5 -b 64k -o foo.m4a foo.wav

For AAC-HEv2, like this:-
(Format profile : HE-AACv2 / HE-AAC / LC)

fdkaac -p 29 -b 32k -o foo.m4a foo.wav

VBR[1-5]

fdkaac -m 3 -o foo.m4a foo.wav

(afterburner is enabled by default, use -a 0 to disable it)
