Shazam Entertainment Ltd, was started in 2000 with the idea of providing a service that could connect people to music by recognizing music in the environment by using their mobile phones directly. The algorithm had to recognize songs in an environment with heavy ambient noise. It also had to perform the recognition quickly over a large database of music with nearly two million tracks. The project used FFT (Fast Fourier Transform) along with Audio Fingerprinting. The noise in the input signals were handled using Gaussian noise filters. It also created a database and a user-friendly interface.
