Hello shafayet
Bitrate doesnt influence the volume, only the soundquality.
The higher bitrate used, the lower the compression, and thus the higher the quality (and filesize)
spawn wrote a small guide for that also, its a litle outdated (some tools mentioned are nolonger available) but the general information is still ok.

Basically you can do it in several ways, either download DB Poweramp for an easy way to simply rightclick a file and select convert to, or you can use Nero Burning Rom, start Nero, press F8 (extras, encode files) then load the files you want to convert, and select your conversion settings. Theres also Itunes which rips/converts to mp4 (though they call it m4a its still the same). DB Poweramp is also a CD ripper that will let you rip straight from CD to mp4 for max quality.
Some things to remember, you wont get better quality than the file you are converting from, you will allways get poorer quality, so if you convert a 128kbps mp3 to mp4 it wont be better quality no matter how high bitrate you choose, as a new compression allways degrade the quality. To get the better quality from mp4 over mp3 you need to rip straght from the CD to mp4 instead of straight from the CD to mp3.
You cannot change the volume of the track in neither Nero or Itunes, but DB poweramp has a selection called "normalize" this will increase the volume of the track you convert if its lower than normal. To increase volume more than that you need to use some audioeditor that will let you import mp3 and save as mp4, I beleive Nero Waveeditor will do that. But remember eveytime you make a new compression quality will decrease.
When ripping from CD to mp4, 160-192kbps gives great quality.
