Audio track waveform not displayed correctly on timeline
The audio track waveform on the timeline is inaccurate and appears 'louder' than it should:
1. I imported an audio file, and "auto volume" was applied to it by Rush, which significantly dropped the volume.
2. I turned off auto volume as I had set the volume for the audio to be exactly what I wanted in my audio program (-0.8dB).
3. The waveform in the timeline then appeared as though Rush had somehow amplified it too much.
4. The volume meter in the bottom right was not helpful as it was showing in the red, but there is no decibel display so I couldn't tell the actual level. The track did not seem to sound distorted, so I cautiously continued, thinking that Rush must just be displaying the waveform incorrectly.
5. I have attached a screenshot, and you can see in the audio settings panel that the waveform definitely does not clip, but the timeline tells a different story.
In my screenshot, you'll see that I included an image of the deselected clip (the image has a blue border around it). The deselected clip clearly does not show the peaks either.
It's not an accurate representation of volume compared to the waveform displayed in the Audio Settings.

This looks normal to me. The music clip appears to be a piece of commercially mastered music that is already really loud, so you wont see much in the waveform other than a solid green waveform (the "caterpillar" as we call it in the audio world). If you de-select the music clip you should see the top of the waveform in the timeline.
Rush uses two different waveform views, the rectified view used in the timeline shows only the amplitude in the Y axis, with no amplitude at the bottom of the clip and full volume at the top of the clip. So, if you de-select the clip, the yellow selection will stop covering the top part of the waveform that will show any valleys and peaks.
