first I converted the final mixed stereo tracks to MP3 , bearing in mind the e.q. & compression levels will need to be different to a c.d. mix
Before remixing your music to MP3 I think you should understand WHY you have to remix the songs. The biggest difference is in the bit rate. A CD will have a bit rate of 1410/sec and the same song in MP3 format will be reduced from 128 to 320 bits/sec. Obviously with all that compression a lot of information is lost. And it's how this loss is done that requires a different mix.
Most MP3 conversions start dropping out the sound at 16k. Unfortunately that is where a lot of what we call 'color' is located. Your musical overtones. The higher quality of the MP# the less loss. But there is a definite loss.
As a rule MP3 conversions generally cut the bass and boost the middle. Think of it as a form of frequency compression. Like volume compression there is less frequency coloring just like there is less dynamic coloring.
Before you start tweaking your EQ you should use a frequency plug in to compare your 1410 bit/sec Cd with the MP3 you've converted (Usually between 192 bit/sec and 256 bit/sec for retail sales). You'll see what and where the differences are and can adjust your EQ AND Volumes to more closely match what you hear on the CD.
