Re-Encode Songs to have a higher volume?

Hey everyone,
On a few of my older CDs, the music playback volume is lower than all of my other music. It’s pretty awkward to increase the volume for just one or two songs on my playlist. The volume difference is so drastic between certain songs that using Volume Leveling back doesn’t even seem to improve it a lot.

Is there a program that I can use to take a music file and re-encode it to playback at a higher volume?
