Could you build this?

Partial The UI and analysis pipeline are buildable, but locating audio in time and place from hum requires a reference database of grid-frequency logs and a specialized signal-processing method that vibe coding won't supply.

What it would actually take: Build a web or desktop front end that accepts audio and runs ENF (electric network frequency) extraction using an FFT-based bandpass and tracking pipeline, written in Python with NumPy/SciPy. The hard parts are curating a reliable, geographically and temporally indexed grid-frequency reference dataset, which requires access to grid operator or third-party logs, and validating the matching algorithm against real recordings, which takes forensic signal-processing expertise.
