One problem I have found difficult is determining the recorded loudness of the total mix, since computer speakers and earphones depend on my volume settings on the computer. It's easy enough to guard against going in excess of 0.0 dB, but what about passages that are to be quiet or subdued?
I have found a plug-in, from a company called TC Electronics that will measure an average loudness, and the documentation says you can use the plug-in to obtain preferred broadcast levels of average loudness. Using the plug-in you not only guard against peaking, but better preserve dynamic levels. The interface provides a kind of "radar screen" that displays an average of output. In this way you have an objective, presumably industry standard, way of measuring the output of your mix while preserving dynmics. The plug-in is called LM2n Loudness Radar, and I place it as the last plug-in in the Master Bus of VE Pro, just before output. I have no connection with this company, other than as a purchaser of their product. There's a YouTube video about the product if you search.
I would be interested to hear what others think of the program. I now use it all the time, toward the end of composition.
