Report
"This book cannot be praised enough. It doesn't contain everything known and done in the area of acoustic echo cancellation and noise suppression, which would be virtually impossible, since papers on that subject are published daily, and patents number in the hundreds. It does contain, however, far more than the basics, and, above all, something extremely important in the area, which is still more of an art than a science: practical guidance. How to select the algorithms, make them work, tweak them, and control them are all topics covered in the book. All of this is supported by a superb mathematical treatment, and a solid body of reference work...In conclusion, this book is a must have reference for digital signal processing (DSP) designers in multimedia, and perhaps for DSP students, as a golden mine for projects."
