Biography
Eric Tarr is an assistant professor of Audio Engineering Technology at Belmont University in Nashville, TN. He teaches classes on digital audio, computer programming, signal processing and analysis. He received a Ph.D., M.S., and B.S. in Electrical and Computer Engineering from the Ohio State University. He received a B.A in Mathematics and a minor in Music from Capital University in Columbus, OH. His work has spanned across the topics of speech signal processing, musical robotics, sound spatialization, acoustic and electronic system modeling, hearing loss, perception and cognition. He has published articles in the Journal of the Acoustical Society of America, Journal of Speech, Language, and Hearing Research, International Journal of Audiology, and Mechanical Engineering Research. He is a member of the Audio Engineering Society. In 2015, Dr. Tarr received the Gibson Foundation Les Paul Music Innovation Award as the principal investigator of a research grant on "Blockchain Technology in the Music Industry."
"Part of Hack Audio’s success is its ability to convey information in a variety of ways. Tarr’s written explanations are always concise but never lacking in information. The page count never feels daunting since large portions of each chapter are dedicated to graphics and sample MATLAB code. The sample code is kept succinct, which should help students understand the purpose of each script. [...] Hack Audio is able to capture readers’ attention through compelling illustrations (i.e., block diagrams, Cartesian graphs) and "visualizations" (i.e., waveforms, characteristic curves, impulse responses, frequency responses, and spectrograms). The block diagrams were a personal favorite and helped to illustrate the interconnectedness of certain audio effects (i.e., inverting the delay used for a notch filter results in a band-pass filter). Students will become comfortable discussing audio effects in a number of different ways: graphically, verbally, and sonically. […] Hack Audio is an unpretentious and pleasant read, buoyed by Tarr’s love and passion for the subject. All students and instructors in an audio-related field should check out the Hack Audio website. Both the blog and textbook will quickly become your favorite go-to resources for digital signal processing concepts." Brandon Cudequest, Threshold Acoustics, LLC. Chicago, Illinois
