NTT demonstrates a service that can identify songs automatically via a mobile phone.
The wireless online service involves sampling algorithms that extract data from the music stream every 0.2-0.3 second for use in the search. The search takes less than 5 seconds. When the title is identified it is displayed on the phone LCD screen.
There were several attempts in the past to come up with a way that allows people to get the title of a song on the radio when they hear it. Sony's Emarker was one of them. The device records the time of the day when the song was played and users could at home look up the songs on their PC. Well it is not available anymore. The NTT solution sounds great. The Mobile Phone becomes the ultimate tool.
