Raytraced Audio - Draft V1 [10:09] - Harsh Feedback Wanted

Hey everyone, I would love to get your feedback on the first draft of my Raytraced Audio video.

Because my script is constantly changing and the timing of the animations must match my voice, I don't polish the animations until the script is final. This draft has freeze frames, sharp transitions, and poor audio, so I'm not looking for feedback on:

transitions / overall video editing

audio / voiceover quality (emotion in my voice, background noise, echo)

I would love your harsh feedback on:

when/why you stopped watching

which parts were confusing

which concepts weren't explained well

if a part of a video felt like filler and can be removed

the overall flow of the video - i.e. more time should be spent on X instead of Y, or if there were there abrupt topic changes

There's also no background music right now. In the final version I want to fade between regular background audio and raytraced/spatialised background audio

Also I don't start talking about raytracing until 2:40. The first couple minutes are spent giving an overview of spatial audio. What are your thoughts on this, do the first 2 minutes feel like filler?

Here is my script, feel free to comment there too.

I am looking for harsh feedback, I'm happy to change the video entirely
