Hidden Microphone in SF Captures Mission District's Street Music

A tech enthusiast's weekend project records and identifies songs played publicly in San Francisco's Mission District.

Riley Walz installed a solar-powered box with a microphone and an old Android phone on a pole in the Mission District.
The device records 10-second audio clips and uses Shazam to identify the songs, uploading them to a public website.
Since its installation, the Bop Spotter has identified over 200 songs, predominantly featuring Spanish-language music.
Walz spent about $100 on the project, which took him around 10 hours to complete, with most of the code written by ChatGPT.
The project has sparked global interest, with people reaching out to Walz for DIY instructions to replicate the setup.
