Room response simulator.

[Liftro]

Hello, in the age of artificial intelligence, is it possible to create or implement a tool that would be useful for people who can't travel or afford to test various speakers? The tool would work by taking the dimensions of our room, asking us if it has any acoustic treatment (in the form of a short survey), and calculating the specific response of that room, taking into account the speaker's own response, to equalize an audio track that a user could upload—a track they are familiar with. This way, we could test how each speaker sounds in our room without having to buy several physical products and compare them. What would be necessary, however, are decent headphones to listen and make decisions. I don't think it would be too difficult, knowing that we have room response calculators and also a large database of speaker responses on Spinorama. Would such a simulation tool be useful?

There's lots of high-end simulation available, I believe. However proper modelling requires full details of the acoustic performance of every surface, together with the underlying construction materials, and if there are irregular spaces its a serious task entering the data... that's once it has been acquired. I found this:

A search gives: Ease, Comsol, Simscale, and Treble Technologies, but I know nothing of them.

I'd love to know of anything that does a 3D scan of the room to provide input data to a modeller.

I suspect this level of modelling is cost-prohibitive for day-to-day use.

Thank you for such a comprehensive response. As soon as I have a moment, I'll read the entire text you wrote. I was more interested in a simple and user-friendly tool that would allow users to approximate how a given speaker might sound in their room through audio samples. I understand that if this were to be a simulation that reflected reality 99.9% of the time, it would probably be too expensive to implement.

Take a look at i-Simpa. No 3D scan, you have to create your own CAD file for the room then import it into the program. But it's free!

I'll definitely try it, thanks.

I would do a search for "acoustical simulation in architectural design." L-Acoustics has software L-ISA for designing speaker placement. I'm aware of it used for stadium or outdoor coverage. And I would read some books on architectural acoustics. You never know what a search of academic journals might turn up. I would also see if ray tracing which is used in image construction applies.

I think simulating an already existing arbitrary room with speaker placement and listening position would be very difficult.

There are many LIDAR systems which do detailed interior scans. Search for LIDAR room interior scanner. They will range in distance covered and detail. They can be purchased, rented, or offered as a service. Some systems capture a photo at the same time which can be fused in software into a very realistic virtual room. I think there may be a device realtors use which combines LIDAR and a movie of the room.

You can just use your phone with apps like Polycam. It’s mostly free
