Much has been speculated about the bitrate. Most people do not understand clearly what it is. A few understand, but almost nobody knows if a file with 320 kbps really sounds different or better than the same file but with 128 kbps.
The easiest way is to test:
The first is at 128 kbps
Now let’s hear the 320 kbps option
Notice the difference? In case the note is because it was encoded using the Mp4Gain.
Normally it is almost impercentible, but using a good encoder you get to notice some subtle difference.
It should be taken into account that at higher kbps, if there is a higher quality – although it is not always noticeable – and will always use more disk space.
Therefore it is not the best option to say “all my mp3s will be 320 kbps”, unless the space does not mean any problem at all.
