sound capture and processing

This book by Ivan Tashev provides a comprehensive yet concise overview of the fundamental problems and core signal processing algorithms for digital sound capture, including ambient noise reduction, acoustic echo cancellation, and reduction of reverberation. After introducing the necessary basic aspects of digital audio signal processing, the book presents basic physical properties of sound and propagation of sound waves, as well as a review of microphone technologies, providing the reader with a strong understanding of key aspects of digitized sounds. The book discusses the fundamental problems of noise reduction, which are usually solved via techniques based on statistical models of the signals of interest (typically voice) and of interfering signals. An important discussion of properties of the human auditory system is also presented; auditory models can play a very important role in algorithms for enhancing audio signals in communication and recording/playback applications, where the final destination is the human ear.
