Audio and Speech Processing with MATLAB by Paul Hill
Requirements: .PDF reader, 22,1 MB
Overview: Speech and audio processing has undergone a revolution in preceding decades that has accelerated in the last few years generating game-changing technologies such as truly successful speech recognition systems; a goal that had remained out of reach until very recently. This book gives the reader a comprehensive overview of such contemporary speech and audio processing techniques with an emphasis on practical implementations and illustrations using MATLAB code. Core concepts are firstly covered giving an introduction to the physics of audio and vibration together with their representations using complex numbers, Z transforms and frequency analysis transforms such as the FFT. Later chapters give a description of the human auditory system and the fundamentals of psychoacoustics. Insights, results, and analyses given in these chapters are subsequently used as the basis of understanding of the middle section of the book covering: wideband audio compression (MP3 audio etc.), speech recognition and speech coding. The final chapter covers musical synthesis and applications describing methods such as (and giving MATLAB examples of) AM, FM and ring modulation techniques. This chapter gives a final example of the use of time-frequency modification to implement a so-called phase vocoder for time stretching (in MATLAB).

The Free Speech Movement: Reflections on Berkeley in the 1960s by Robert Cohen, Reginald E. Zelnik
Requirements: .PDF reader, 3,5 Mb
Overview: This is the authoritative and long-awaited volume on Berkeley’s celebrated Free Speech Movement (FSM) of 1964. Drawing from the experiences of many movement veterans, this collection of scholarly articles and personal memoirs illuminates in fresh ways one of the most important events in the recent history of American higher education. The contributors―whose perspectives range from that of FSM leader Mario Savio to University of California president Clark Kerr―-shed new light on such issues as the origins of the FSM in the civil rights movement, the political tensions within the FSM, the day-to-day dynamics of the protest movement, the role of the Berkeley faculty and its various factions, the 1965 trial of the arrested students, and the virtually unknown "little Free Speech Movement of 1966."
