audition cc 2015 save audio in acc question?

hi

may i ask 3 questions about audition cc 2015 acc codec ?

1)

which encoder does it use?

2)

to save in acc i have to select windows media fondation to have all the option

because in MPEG 2-ACC i can select only bitrate and sample type

3) could adobe add the possibility to export to an external codec  maybe via a command line ?

this will be great , so we could use other codec via command line , like lame or nero acc or itune acc

under windows there are lots of tools that can do it like TAudioConverter , i know i can export to wave and encode with TAudioConverter

but work with audition would be really amazing , for example the Batch Process with command line will be awesome

thanks
