Hack Audio: An Introduction to Computer Programming and Digital Signal Processing in MATLAB

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, more than 200 examples with completed code demonstrations are provided.

The book begins with chapters on the basics of MATLAB with programming and audio. MATLAB is then used to solve examples throughout the book, with Signal Processing Toolbox used in some examples.
