How to normailize loudness for YouTube with DaVinci Resolve

The goal of this tutorial is to normalize audio loudness at -14LUFS and True Peak -1.5dB with DaVinci Resolve for YouTube.
Audio mastering/normalization is very important. If your audio levels are too low, viewers will not hear well. If they are too high, clipping and distortions will lower the quality. On top of that, platforms like YouTube expects you to upload materials with certain loudness. If your loudness is too high, YouTube will lower your videos volume. But if it’s too low, it will not bring the volume up.
Setting correct audio level by ear is not the best idea. Luckily, loudness can be measured with LUFS and we can modify audio tracks to reach desired loudness. In this tutorial I will show you how to do it with DaVinci Resolve for YouTube.
