If you caught my last post about the issues I was having with YouTube degrading my voiceover sound quality to an unacceptable low, you'll know I was breathing a sigh of relief when I found the very, very simple fix!
It truly was just as bring the voice over down in the mix. You might say, "Dana, why didn't you try this before now?", and I will tell you, I did! But it wasn't enough. I brought it down quite a bit more, and even though it didn't seem to make that big of a difference in volume (clearly, the voiceover is still perfectly audible), it was enough to let the dynamic range of the music shine more than the limited range of the voice. I guess that's the trick! It's working today, anyway. See for yourself:
