FFmpeg command to convert MP3 to AAC

I can issue this command:

ffmpeg -i input.mp3 -acodec alac -ab 128k -ar 48000 -ac 2 -y output.m4a

to create a m4a file.

But when I issue this command

ffmpeg -i input.mp3 -acodec alac -ab 128k -ar 48000 -ac 2 -y output.aac

ffmpeg is throwing an error saying

Could not write header for output file #0 (incorrect codec parameters ?).

Also, the size of the m4a…
