I’m thinking about a search engine that search based on a sound input. For example, if we sing a part of a song to the microphone connected to computer, then the search engine can give us information related with the song we sang such as artist, mp3 file, etc.
I imagine, our voice will be translated into a chart in certain pattern. The pattern then be used to search into the database to find similiar pattern. Ofcourse at first, we have to translate songs / voices into this kind of data (chart).
I even imagine that if we play a guitar cover of a song, then we can find the mp3 file of the song.
Still trying to find right schedule to start.
