I've been trying to figure out how to program for Media Player's built-in eq in VB6, as that's what I'm using in the frontend that I'm writing. I'm not in it for the sound comps, just my own personal preference. And as far as listening to music on CDs, that kinda defeats the purpose of a carputer a lil bit LOL. At 80km/h with the windows down, you can't tell the diff between the original recording and an mp3 ripped at 160kbps. Might make a difference to those who have air conditioning tho LOL. All of my music will be in MP3 format, except for the odd CD that someone may want to listen to in my car.
