[qute]is that mean MP4 file can't with PCM audio? i have to using AAC or AC3 audio format to encode?[/quote]
No, the mp4 standard does not allow wav audio inside the container.
Personally I would probably use flac and mkv as container.
What's the criteria to be the best audio bit rate?
Why use bit rate and not quality factor?
For most content 320kbit/s aac is fine for 5.1 audio so your bit rates are possible, but probably a waste of bit rate.
If you are not using lossless x264 compression, then why aim for lossless audio?

Quote:is there anyway to encode MP4, x264+PCM? because i want to keep the best qualityAny lossless audio i.e. ALAC (apple lossless audio codec; supported through qaac) would not change the quality.
Personally I would probably use flac and mkv as container.
Quote: what's the best bitrate of AAC to set? can it reach 3072 or 1510?No clue how to answer that.
