“It does so with an integrated app that passively collects audio fingerprints for all programming, both live and playback. Every single program automatically has an audio fingerprint, which is a condensed digital summary generated from an audio signal. The app simply matches it to a database that ingests all programming content across networks and streaming channels. The San Francisco startup, which launched in September 2015, depends on a diverse panel of users who run the app in the background of mobile devices, TVs, or laptops. The app offers brand-new insight into consumer behavior.”
