Head-Related Transfer Function and Virtual Auditory Display (A Title in J. Ross Publishing's Acoustic)
This book systematically details the basic principles and applications of head-related transfer functions (HRTFs) and virtual auditory display (VAD), and reviews the latest developments in the field, especially those from the authors own state-of-the-art research group.
In this updated second edition, Head-Related Transfer Function and Virtual Auditory Display covers binaural hearing and the basic principles, experimental measurements, computation, physical characteristics analyses, filter design, and customization of HRTFs. It also details the principles and applications of VADs, including headphone and loudspeaker-based binaural reproduction, virtual reproduction of stereophonic and multi-channel surround sound, binaural room simulation, rendering systems for dynamic and real-time virtual auditory environments, psychoacoustic evaluation and validation of VADs, and a variety of applications of VADs.
Key Features:
--Discusses and summarizes the basic principles and applications of head-related transfer functions and virtual auditory display
--Reviews the frontiers and latest approaches (modeling, calculations, rendering/display) in HRTF and VAD, useful for researchers, graduate students, and engineers in the field
--Applications from this research can be found in engineering, communications, multimedia, consumer electronic products, and entertainment
--More than 600 references are listed, encompassing the majority of literature in this field
Why Read This Book
You will learn a practical, DSP-centered approach to binaural audio: how HRTFs are measured, modeled, filtered and used to create convincing virtual auditory displays. The book blends theory, signal-processing algorithms and hands-on system design so you can move from measurements and spectral analysis to implementing real-time headphone and loudspeaker binaural renderers.
Who Will Benefit
Engineers and researchers in audio, acoustics, or communications with some DSP background who need to design, measure, or implement HRTF-based binaural and virtual-audio systems.
Level: Intermediate — Prerequisites: Basic digital signal processing (Fourier transforms, filtering), introductory acoustics and psychoacoustics, and practical experience with MATLAB or Python for signal analysis.

How It Compares
Covers similar practical and DSP-oriented ground to Jens Blauert's Spatial Hearing but is more implementation-focused; complements Ville Pulkki's work on spatial sound reproduction by emphasizing HRTF measurement, filter design, and customization.
