Data-driven methods in description-based approaches to audio information processing

Hearing is a part of everyday human experience. Starting with the sound of our alarm clock in the morning there are innumerable sounds that are familiar to us and more! This familiarity and knowledge about sounds is learned over our lifetime. It is our innate ability to try to quantify (or consciously ignore) and interpret every sound we hear. In spite of the tremendous varieties of sounds, we can understand each and every one of them. Even if we hear a sound for the first time, we are able to come up with specific descriptions about it. The descriptions can be about the source or the properties of its sound. This is the listening process that is continuously taking place in our auditory mechanism. It is based on context, placement and timing of the source. The descriptions are not necessarily in terms of words in a language, it may be some meta residual understanding of the sound that immediately allows us to draw a mental picture and subsequently recognize it.
