About quality if render mp3 file second time

I have music mp3 file with, but volume level too low. If I normalize it and then to render with the same bitrate, what's happen with sound quality?
Could I recognize orally any degradation?
Thanks to all.

Any time you have a media file compressed in a lossy format (ie; jpg, wmv, mpg2, mp3...), recompressing it in a lossy format you will lose some quality, as additional data will invariably be lost. How much depends on the quality of the encoder and it's settings. IF the difference is noticable depends in part on the quality of the original compressed file, the content, and the original encoding settings - may work well on some, not so well on others.
