if you go over 0 db you have clipping....that means reduced soundquality. it's best to stay under it. you could use a limiter to keep things under 0 db. but it's best to mix your tracks to -1 db.
so the person who masters your track has some room. and why does everything have to sound loud? just make sure everything is sounding in balance and don't base yourself on how loud it sounds.the person who will master your tracks knows what to do with that.

on a audio cd you have a max of about 96 DB of dynamics the term for that is "0DBFS" (FS stands for Full Scale).
so 0 db is the max headroom you have. everything above that distorts (called clipping). here's a a picture that will make it clear.

on the top we see a sine on 0db. nothing wrong with that. on the bottom we have a sine that goes above 0db. see what happens?? your sine bumps its "head" agains the "ceiling".
the sine doesn't have anymore headroom and distorts. and that will also happen to your sound when you go above the 0db limit.

also the 96 db is when you record in 16 bits. if you record in 32 bits you have 144 dbSPL (sound pressure level)

the 96 db= 16 bit because every bit is 6 DB the 144 db= 24 (24-6db=144)

that 32 bit should be 24 bit

96 db = 16 bit <--(16 times 6db= 96) 144 db= 24 bit <--(24 times 6db= 144)
i can't type

but do you understand the post with the picture? that's the important part.
you can ignore the rest. I don't even get that 100% to be honest. it's just audio geek talk.

as far as I know the decibel system is relative system of measurement.
I thought I'd type that.
