Why is it that i can never produce a recording even close to the volume of a cd (using protools) even though my levels are almost to zero and are about to clip yet i still sound 6 to 10 db lower then a cd

Joris said:There is a LOT more to it than that. The art of mastering is to get a dynamic sound, yet with a very small difference between loud and soft, decibel-wise. This means compression on every individual track, compression on track groups, and (preferably multi-band) compression on the master track.
Geez, even the tiniest bit of processing messes with your signal. Even moving a fader will introduce rounding errors. Not to mention EQ - but we can't live without EQ, right? If you that easily can identify rounding errors in a normalized 24-bit signal, I want your ears. And your monitors. Normalizing is quite simple math compared some other algorithms used in DSP operations, so any rounding errors should be tiny.fulcrum said:IMNTLBHO the normalize function is pure Satan-- I don't care which package you use to accomplish it, it messes with your signal. Yes, it will quick-and-dirty your peaks up to 0db VU, but in multiplying the other samples (the ones in between your peaks, which are responsible for your tone) you run the risk of introducing slight distortions due to rounding errors, which will be audible to a small degree at the very least.
Well, that helps, but the problem is that your gain increases only to the point that your highest peak reaches 0 dB. By compressing prior to normalizing, the dynamic range is decreased, narrowing the difference in volume between the peaks and lower volume material. Then when you normalize, the material that would otherwise be well below the peaks realizes a bigger gain.jive1 said:It's not the same as a mastering engineer, but I use the "normalize" function in a wav editor or multi-tracker program to get the sound to CD level.
