Should we window the impulse response?

Windowing can be an important part of noise reduction of our measurements to aid in further investigation of interaction direct sound and reflections.
This is a video response to the question from Toast on Toast in last week's live stream. I used the weird ai art because I thought it was funny.

I love to geek out about the physics of sound. This channel focuses on the growing opportunity for live sound engineers to improve their confidence and consistency through the understanding of the principles of sound system design and optimization. My goal is to make this channel upfront and honest about my success and failure, so you can learn from both.
I am always open to suggestions and feedback so please comment on this video or contact me through my site.

Thank you so much Nathan for going further into my question. I appreciate the time and effort you have taken to look into this suggestion.
To be honest, windowing came about to me as a result of desperation and frustration with "noisy" traces.
As you said, the Relative/Absolute method is still the best method, and Sub Aligner remains the ultimate tool for the job in the field.
Thank you to you, and the good folk(s) over at CrossLite for the answers.
Looking forward to the next live stream!

You're welcome! Hey I'd love to get more of your questions and thoughts on this topic. Would you be down to chat? If so, here's a link to my scheduling page: nathanlively.as.me/qa

Yes. Always apply a window. There is actually no way to avoid a window. No window is essentially a box car window. The width and type of window will determine how the response is shaped. I expect the manual for any software will describe the effect each window type has on the measurement.

[@nathanlively]

Thanks Nack! I believe I covered this by saying, "The minimum window necessary to perform the FFT." In this video I'm focusing on applying further windows specifically to perform kinds of noise reduction.

Hey Nathan! I was wondering if there's any chance you could record Crosslite online training.

[@nathanlively]

Yes! I've done several. Last year I tried to sell a training, but there was not enough demand, so maybe we'll see in the future. If you just search my channel for CrossLite, you'll find them.
