Tools for Automatic Audio Management

Abstract

The purpose of this chapter is to introduce tools for automatic audio management. The authors present applications which are already available for the users and describe the algorithms and methods behind these applications and their performance. They also discuss the concept of metadata, which is an important prerequisite for modern distributed personal content applications. The variety of automatic audio management tools is wide-ranging. This chapter covers audio segmentation and classification, query by example of audio, music retrieval and recommendation, and speech management, which they consider as being the most important aspects of audio information management. Computational complexity is one major concern in the present era of personal mobile devices and large multimedia collections available on the internet. Therefore they also introduce clustering and indexing techniques which are developed for faster access in large databases.
