Hack Audio

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.

Digital Audio Theory: A Practical Guide bridges the fundamental concepts and equations of digital audio with their real-world implementation in an accessible introduction, with dozens of programming examples and projects. Starting with digital audio conversion, then segueing into filtering, and finally real-time spectral processing, Digital Audio Theory introduces the uninitiated reader to signal processing principles and techniques used in audio effects and virtual instruments that are found in digital audio workstations. Every chapter includes programming snippets for the reader to hear, explore, and experiment with digital audio concepts. Practical projects challenge the reader, providing hands-on experience in designing real-time audio effects, building FIR and IIR filters, applying noise reduction and feedback control, measuring impulse responses, software synthesis, and much more. Music technologists, recording engineers, and students of these fields will welcome Bennett’s approach, which targets readers with a background in music, sound, and recording. This guide is suitable for all levels of knowledge in mathematics, signals and systems, and linear circuits. Code for the programming examples and accompanying videos made by the author can be found on the companion website, DigitalAudioTheory.com.

Since the dawn of film, novices and experts have used quick-and-dirty workarounds and audiovisual tricks to improve their motion pictures, from home movies to feature films. Today, the tools have certainly changed, as have the quality and scope of the results. With digital video, the hacking possibilities are now limitless, for both amateurs and professional artists. From acquiring footage, mixing, editing, and adding effects to final distribution, Digital Video Hacks provides unique tips, tools, and techniques for every stage of video production. You'll learn how to: Get your projects started right using creative preparation tools and techniques,from making your own steadicam, boom, or dolly to effective storyboarding, timecoding, and tape labeling Troubleshoot common shooting problems, including using stop-motion and time-lapse techniques, lighting effects, colored screens and gels, and household objects to establish mood or otherwise wow an audience Create stunning visual effects, such as satellite zooming, surreal scenes, Matrix-like bullet-time, and green screen illusions Fool your audience with audio tricks, replacing flubbed dialogue, smoothing over cuts, and covering missing audio with room tone Add professional features with post-production tricks, including color correction, soundtrack cleanup, opening sequences, and DVD bookmarks Distribute final content in a variety of creative ways, from exporting to basic videotape or DVD to streaming over the internet or even via cell phone Use the web to provide interactivity and dynamic content, attend a remote conference, or vlog your life. Whether you're looking for a new technique to include in your next project, a solution to a common problem, or just a little inspiration, this book reintroduces you to the digital video you only thought you knew.

Mac OS X is a wonderful combination of the power and flexibility of Unix with the ease of use that seems to come only from Apple. Between the tools baked right into the system, a veritable cornucopia of third-party applications, and a cottage industry of customizations, tweaks, and hacks, the Mac is a force to be reckoned with like never before. Mac OS X Panther Hacks celebrates the Macintosh's adventurous spirit, inviting the citizen engineer on a quest of deeper discovery -- both with the purpose of going further and simply enjoying the ride. Mac OS X Panther Hacks continues the tradition started with Mac OS X Hacks, sitting squarely at the peculiar confluence of deadly earnest optimization and creative (albeit sometimes wacky) tweaking you seem to find only on a Mac.
