Choose your audio and start the check.
Is the selected reference a required YouTube upload level?
No. The reference is a comparison setting for your audio. YouTube playback can include volume and audio enhancements, so a measured file and a selected target do not predict every listener’s experience.
Keep dialogue easy to follow
Check transitions between speech, music, and effects. A comfortable overall loudness can still contain abrupt jumps. Use the plot to find sections to review, and check the audio again after the final video export.
