Error in NeroDigitalAudio

[rocky12]

I just confirmed my audio is PCM. It means my commands are wrong. Here is the command I have with the error output. I don't remember the commands.

neroaacenc -br 256 -i sound.wav -o sound.mp4.........wrong??? What should it be?

Reason for error. It's NOT -i and -o. Lame uses it like that. It should be the following.

neroaacenc -br 256 -if input.wav -of output.mp4
