Shazam’s most familiar use case finds it’s users in loud bars or clubs, hearing a song they like but don’t recognise, and holding the app near a speaker so it can’t tell them what it’s called. The app identifies published songs based on a spectogram of three dimensions of music: frequency, amplitude, and time. It then takes that ‘fingerprint’ and compares it against a database of 11 million songs to find a match.
But the technology can be used in some alternative and creative ways as well. Here, Shazam have partnered with the Children’s Society and others to install digital panels in Singapore that interact with the Shazam app.
The panels project a sound wave undetectable by humans, but that can still be picked up by our smartphones. Opening the app and Shazamming whilst nearby will fire up a video, and in the process give a boy named Daniel a voice to tell his story to you.
