Changing a video's audio codec from one to another on ffmpeg

How is definitively changing a video's audio codec from one to another as specified by ffmpeg

in short, ffmpeg gives specs on a video's audio stream

Code:

Stream #0:1[0x2](und): Audio: aac (HE-AAC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 47 kb/s (default)

which must be another that ffmpeg has given a specs on another video's audio stream

Code:

Stream #0:1[0x2](und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, mono, fltp, 64 kb/s (default)

How the correct way of solution ?

So you want to transcode the audio stream without touching the video stream?

Code:

ffmpeg -i badaudio.video -v:c copy -v: a <insert_audio_codec_stuff_here> goodaudio.video

Take care that you choose a compatible container for the final output.
