Computers are at the center of almost everything related to audio. Whether for synthesis in music production, recording in the studio, or mixing in live sound, the computer plays an essential part. Audio effects plug-ins and virtual instruments are implemented as software computer code. Music apps are computer programs run on a mobile device. All these tools are created by programming a computer. Hack Audio: An Introduction to Computer Programming and Digital Signal Processing in MATLAB provides an introduction for musicians and audio engineers interested in computer programming. It is intended for a range of readers including those with years of programming experience and those ready to write their first line of code. In the book, computer programming is used to create audio effects using digital signal processing. By the end of the book, readers implement the following effects: signal gain change, digital summing, tremolo, auto-pan, mid/side processing, stereo widening, distortion, echo, filtering, equalization, multi-band processing, vibrato, chorus, flanger, phaser, pitch shifter, auto-wah, convolution and algorithmic reverb, vocoder, transient designer, compressor, expander, and de-esser. Throughout the book, several types of test signals are synthesized, including: sine wave, square wave, sawtooth wave, triangle wave, impulse train, white noise, and pink noise. Common visualizations for signals and audio effects are created including: waveform, characteristic curve, goniometer, impulse response, step response, frequency spectrum, and spectrogram. In total, over 200 examples are provided with completed code demonstrations.

"Explores how industry has manipulated our most deep-seated survival instincts."—David Perlmutter, MD, Author, #1 New York Times bestseller, Grain Brain and Brain Maker The New York Times–bestselling author of Fat Chance reveals the corporate scheme to sell pleasure, driving the international epidemic of addiction, depression, and chronic disease. While researching the toxic and addictive properties of sugar for his New York Times bestseller Fat Chance, Robert Lustig made an alarming discovery—our pursuit of happiness is being subverted by a culture of addiction and depression from which we may never recover. Dopamine is the “reward” neurotransmitter that tells our brains we want more; yet every substance or behavior that releases dopamine in the extreme leads to addiction. Serotonin is the “contentment” neurotransmitter that tells our brains we don’t need any more; yet its deficiency leads to depression. Ideally, both are in optimal supply. Yet dopamine evolved to overwhelm serotonin—because our ancestors were more likely to survive if they were constantly motivated—with the result that constant desire can chemically destroy our ability to feel happiness, while sending us down the slippery slope to addiction. In the last forty years, government legislation and subsidies have promoted ever-available temptation (sugar, drugs, social media, porn) combined with constant stress (work, home, money, Internet), with the end result of an unprecedented epidemic of addiction, anxiety, depression, and chronic disease. And with the advent of neuromarketing, corporate America has successfully imprisoned us in an endless loop of desire and consumption from which there is no obvious escape. With his customary wit and incisiveness, Lustig not only reveals the science that drives these states of mind, he points his finger directly at the corporations that helped create this mess, and the government actors who facilitated it, and he offers solutions we can all use in the pursuit of happiness, even in the face of overwhelming opposition. Always fearless and provocative, Lustig marshals a call to action, with seminal implications for our health, our well-being, and our culture.

Learning Chinese can be frustrating and difficult, partly because it's very different from European languages. Following a teacher, textbook or language course is not enough. They show you the characters, words and grammar you need to become proficient in Chinese, but they don't teach you how to learn them! Regardless of what program you're in (if any), you need to take responsibility for your own learning. If you don't, you will miss many important things that aren't included in the course you're taking. If you study on your own, you need to be even more aware of what you need to do, what you're doing at the moment and the difference between them. Here are some of the questions I have asked and have since been asked many times by students: How do I learn characters efficiently? How do I get the most out of my course or teacher? Which are the best learning tools and resources? How can I become fluent in Mandarin? How can I improve my pronunciation? How do I learn successfully on my own? How can I motivate myself to study more? How can I fit learning Chinese into a busy schedule? The answers I've found to these questions and many others form the core of this book. It took eight years of learning, researching, teaching and writing to figure these things out. Not everybody has the time to do that! I can't go back in time and help myself learn in a better way, but I can help you! This book is meant for normal students and independent language learners alike. While it covers all major areas of learning, you won't learn Chinese just by reading this book. It's like when someone on TV teaches you how to cook: you won't get to eat the delicious dish just by watching the program; you have to do the cooking yourself. That's true for this book as well. When you apply what you learn, it will boost your learning, making every hour you spend count for more, but you still have to do the learning yourself. This is what a few readers have said about the book: "The book had me nodding at a heap of things I'd learnt the hard way, wishing I knew them when I started, as well as highlighting areas that I'm currently missing in my study." - Geoff van der Meer, VP engineering "This publication is like a bible for anyone serious about Chinese proficiency. It's easy for anyone to read and written with scientific precision." - Zachary Danz, foreign teacher, children's theatre artist About me I started learning Chinese when I was 23 (that's more than eight years ago now) and have since studied in many different situations, including serious immersion programs abroad, high-intensity programs in Sweden, online courses, as well as on the side while working or studying other things. I have also successfully used my Chinese in a graduate program for teaching Chinese as a second language, taught entirely in Chinese mostly for native speakers (the Graduate Institute for Teaching Chinese as a Second Language at National Taiwan Normal University). All these parts have contributed to my website, Hacking Chinese, where I write regularly about how to learn Mandarin.
It might be the long lines at the theater, the $4.00 for a small bag of popcorn, or the cutting-edge technology that's now so readily available to the home market. Whatever the reason, the home theater market today is booming like the soundtrack to Star Wars! Want proof? A Google search for home theater reveals over three million results. Yikes! It's simply undeniable: More and more people prefer watching their favorite movies, television shows, and videos from the comfort of their own sofas and couches. What's also undeniable is the inexperience of most people who choose to install or upgrade their home theaters. Until now, the knowledge, technique, and experiences of those who've encountered similar conditions to yours could only be accessed through laborious web searches, stacks of magazines, and water cooler conversations. Home Theater Hacks from O'Reilly is the perfect remedy for this group. A smart collection of insider tips and tricks, Home Theater Hacks covers home theater installation from start to finish, purchase to experience. Just imagine: no frustrating trial-and-error process and better yet, no expensive appointments with installation experts. Home Theater Hacks prevents both by imparting down-and-dirty technique not found anywhere else. The book begins with a quick glossary of terms so you can speak the lingo when you go shopping, and then dives right into hush-hush, insider tricks. It's all covered where to find the right audio and video components, how to deal with speakers and wiring, understanding cable connectivity, mastering remote controls, how to fully grasp TiVo, and so much more. And to top it off, each of these insider tips is presented in a concise yet delightfully entertaining style. Bringing the Jurassic Park dinosaurs into your living room has never been so easy! A seasoned veteran with numerous O'Reilly titles under his belt, author Brett McLaughlin leaves no stone unturned in helping you customize your home theater experience to your own personal environment.
