Voice and sounds are the primary media employed for human communication. Humans are able to exchange information smoothly using voice under different situations, such as a noisy environment and in the presence of multiple speakers. We are surrounded by various sounds, and yet are able to detect the location of a sound source in 3D space, extract a particular sound from a mixture of sounds, and recognize the source of a specific sound. Also, music is composed of various sounds generated by musical instruments, and directly affects our emotions and feelings. This paper introduces real-time detection and identification of a particular sound among plural sound sources using a microphone array based on the location of a speaker and the tonal characteristics. The technique will also be applied to an adaptive auditory system of a robotic arm, which interacts with humans.
