Hi, I was wondering if you can suggest any free program that can remaster MP3 files so that I can improve the sound quality of some of my MP3 music files. I have this MP3 music file of an unreleased song and it doesn't even feature a bass guitar, I was hoping if I could remaster the song digitally, I can improve its quality.
Since MP3 is lossy any changing of it would also detail transcoding ("re-encoding") it after you've changed the bass settings, this equals a reduction in the original quality.
What you could do without any editing of the original file is to use DSP plugins/Equalizer in your media player such as Winamp, Foobar2000, etc., to change the sound.
