Stowie101 writes "Today is Dynamic Range Day, which is an event to educate the public about the 'Loudness Wars' that are compressing and harming the quality of today's music. Ian Shepherd, a mastering engineer and founder of Dynamic Range Day, explains why music lovers should avoid MP3 files. 'The one that springs to mind is to avoid MP3, especially if it's 128 kbps. Apple uses a more advanced technology called AAC, but if someone can get lossless files like FLAC that's a better place to start.' Shepherd says it's actually harder to make a good 'lossy' encode of something that has been heavily musically compressed. Very heavy dynamic compression and limiting makes MP3s sound worse, so the loudness wars indirectly make MP3s sound worse."
