I struggled with my first few Pro Tools sessions because while I was mixing and mastering, things sounded good to me, but then when I'd post them here, I'd get lots of comments about how it was lacking low end and sounded kind of weak compared to my older recordings. Well, I think I've finally figured out why that is. I finished recording and mixing/mastering my recordingfest entry this morning. I bounced the mix/master down to a wave file and also as an mp3. Then I burned both to a CD to listen to on the way to work. The mp3 is much quieter and lacks a lot of punch that is present in the wave file. So, I think my problem all along has been my mp3 encoder. I used Musicmatch Jukebox on my old computer, but I've been using either Windows Media Player or encoding direct to mp3 from Pro Tools on the new system. Even at 192kbps sample rate, the mp3 sounds like crap compared to the wave file, and on the old system, I could barely hear a difference between mp3 and wave, even when I encoded the mp3 at 128 kbps. So, I think I'm going to try to get Musicmatch on my new machine and see if that solves my problems. Just thought I'd share.
