fdkaac build on Freebsd

[NapoleonWils0n]

fdkaac allows you to convert audio to the aac format
it has superior quality to the standard aac encoder and additional options

Due to licensing restrictions fdkaac cant be distributed as a port or package

However it really quick and easy to build it

Options for raw (headerless) input:
 -R, --raw                     Treat input as raw (by default WAV is
                               assumed)
 --raw-channels <n>            Number of channels (default: 2)
 --raw-rate     <n>            Sample rate (default: 44100)
 --raw-format   <spec>         Sample format, default is "S16L".
                               Spec is as follows:
                                1st char: S(igned)|U(nsigned)|F(loat)
                                2nd part: bits per channel
                                Last char: L(ittle)|B(ig)
                               Last char can be omitted, in which case L is
                               assumed. Spec is case insensitive, therefore
                               "u16b" is same as "U16B".

Tagging options:
 --title <string>
 --artist <string>
 --album <string>
 --genre <string>
 --date <string>
 --composer <string>
 --grouping <string>
 --comment <string>
 --album-artist <string>
 --track <number[/total]>
 --disk <number[/total]>
 --tempo <n>
 --tag <fcc>:<value>          Set iTunes predefined tag with four char code.
 --tag-from-file <fcc>:<filename>
                              Same as above, but value is read from file.
 --long-tag <name>:<value>    Set arbitrary tag as iTunes custom metadata.
 --tag-from-json <filename[?dot_notation]>
                              Read tags from JSON. By default, tags are
                              assumed to be direct children of the root
                              object(dictionary).
                              Optionally, position of the dictionary
                              that contains tags can be specified with
                              dotted notation.
                              Example:
                                --tag-from-json /path/to/json?format.tags

fdkaac usage

fdkaac -m 5 input.wav -o output.m4a

Another option is to enable the fdk-aac option in ffmpeg. If you're interesting in AAC there's also audio/exhale (exhale) in ports which performs very good.

 

[NapoleonWils0n]

yes you can enable the fdk-aac option with ffmpeg your right

but it does mean having to build ffmpeg with poudrire if you are using packages
which can take a while

i was trying to avoid building ffmpeg
and it only takes a couple of minutes to build fdkaac

so that was the quickest option
