Can an LLM "See" a Room Just by Listening?

Everyone is using LLMs wrong. We are obsessed with Speech-to-Text. We take audio, flatten it into text, and feed it to a chatbot.

But what happens if you bypass the text entirely?

What if you feed the raw acoustic tensor data directly into a native multimodal LLM and ask it to connect the physical dots?

I am running an experiment to see if an AI can blindly "see" a room just by listening to it.

The Experimental Setup

I am blasting a 3kHz–6kHz broadband frequency chirp (a mathematical "bell ping") inside a highly reverberant, non-rectangular tile box.

The Bounds: Tight. X=104", Y=101", Z=97".
The Geometry: It is a geometric nightmare. There’s a 21.5-inch inward offset on one wall acting as a diffuser.
The Obstacles: A urinal sitting at coordinate (0, 45, 32) and a toilet at (0, 76, 0).
The Target: My primary test target is located precisely at (0, 23, 15).

The Traditional Approach

Normally, calculating this requires hardcore Synthetic Aperture Sonar (SAS) math. You sweep a directional emitter, capture the sound from multiple microphone edges (M1, M2, etc.), and calculate the Time Difference of Arrival (TDOA).

For my target object, the acoustic shadow hits at exactly ~1.92 ms.

The "Crazy" Idea

Instead of writing a manual C++ or Julia script to subtract the empty room baseline ($\Delta R(t)$) and plot intersecting hyperbolas, what if we just feed the raw, overlapping multipath reflection audio directly into an LLM as native tokens?

No text. No pre-processing. Just raw environmental interaction data.

If the model can understand the hidden sequential context of a billion text parameters, can it implicitly learn the physics of sound propagation? Can it identify that the localized energy redistribution at 1.92 ms is an 8-inch object, while the dense tail after 10 ms is just the tile ceiling?

Can an LLM act as a biological auditory cortex and map a 3D coordinate system entirely in the dark?
