Noticed I have 111 views and no responses so I thought I would add to my original post after doing more research. Seems as though the streaming outlets and Youtube are looking for -15 to -13 LUFS depending which one yo are talking about and most store bought CD's of pop, country etc. are mastering at anywhere from -11LUFS all the way to -8 LUFS. Many are of the opinion that if your music is pop or country that a good range is -12LUFS to -8 LUFS depending on the style of music and each song. If a person wants to create more than one master for each outlet I guess that would be the best but is not really necessary because if you are over their standard they are just going to turn it down. One does need to be very careful of the peaks though because if they have to shave those that could change your sound some. Of course depending on other things the outlets may do, the quality of your music may change and usually not for the better but how you handle your master probably won't effect that. So for now unless someone steers me in a different direction I am going to keep my peaks at at least -1db and do my mastering at -12LUFS to -10LUFS probably just under what most store bought CD's of my style are done at. The pro's are experts at squeezing every db out without totally ruining the dynamic feel. That is an art in and of itself and at times also takes some pretty expensive hardware. My ears will determine the final volume tweaks so each song on my CD sounds appropriate and does not require a listener to adjust the volume control on whatever device they are listening on. I realize that through gain staging, eq's, compression, volume maximizers etc. there are several ways to hit the numbers I am shooting for and those ways WILL effect the sound of each song. And I guess that is why everyone can't overstate how important it is to get the mix right before the final mastering stage whether you are mastering yourself of sending it to a professional mastering house. Please feel free to chime in.
