Record. Digitize analog medium. 2. Recording:. Hardware Requirements. Computer with a sound card. Almost all computers nowadays are equipped with a sound card.. Sound card. 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. 3.1 Characteristic of sound and digital audio.. Sound is based on two things: . Energy and Transport Medium. Energy from a banging drum is converted into pressure that is transmitted by the air.
