I like my Mixes I have but when I bounce the song and burn it to a disc and play it the sound is bad like weak . Any help? Im using logic 8 Thanks
depends of course by what you mean by weak, but if the listening environment remains the same there is no reason by a song summed from distinct tracks should sound significantly different from those tracks not rendered to a single stereo pair.
if the CD issue is purely volume you need to check master volume on the mix. Some DAWs default to -3dB on mix as a safty messure to try to keep rendering of the summed tracks below 0 dB not sure whether that is feature/fault of Logic or not. But it is something to check.
If volume is the issue simply adjusting the rendered track will resolve that.
If you are working in 24bit (or 32bit float) it is possible that even in the same listening environment you might notice some difference in transient detail and reverb tail when stepping down to redbook 16bit. but those differences tend to be relatively subtle and are unavoidable. In fact in some ways the better the mix in 24bit the more change can be detected in the step down
if you are not writing a Redbook CD but a data one with some format other then lossless AIF or WAV , MP3 for example then an auditory, even if using the same listening environment, difference is also to be expected
The most common source of problems between a mix listened to via DAW and CD is a change in the listening environment. If a mix is executed in a typical home recording room with, among other things, standing wave bass modes then it is possible that the summed, mixed CD render can sound 'weak'. It is also possible that editing the rendered track via what is commonly referred to as mastering can alleviate some of the issues
not proposing that people not master tracks but trying to fix most of the above via 'mastering' rather then in the mix tends to be counter productive
