I need to develop an iPhone application that can recognize a song and when someone else is playing the song the engine is able to tell me the play time of the song(e.g. 01:05). For example, when user A is playing half way of the song and user B shake the iPhone then user B will know the current play time(01:05) of the song.
I just need the engine that can train and recognize the song and I will handle the integration and UI design potion.
The project timeline is within 20 days.
