On this page, you will find some articles on certain topics in sound design and audio engineering. I wrote those articles, because i believe that a solid understanding of the underlying principles of sound and music is a major benefit when using audio processing software. I wrote the articles in the style of short memos, each on one topic at a time and I hope, those memos will give the reader insights which enable them to use audio software more successfully in order to create better music.
Signals, Power and RMS - explains, what signals in general are, how their power and RMS-value is defined.
Pan Rules - introduces the two most important pan-rules, namely: linear and constant power
Amplitude and Decibels - explains, what amplitude is and how the ubiquitous decibel is defined.
Frequency and Pitch - explains, what frequency is and how our tone system is derived from that.
Sinusoids and the Frequency Domain - gives a brief overview over sinosoids, their use in additive synthesis and scratches at the surface of fourier analysis.
Filter Basics - a basic introduction into the rich and diverse field of filters and how they are used in audio engineering. Filters are very important devices and when you look closer, they pop up almost everywhere (not only, but also, in the audio processing domain).
Digital Signals - Sampling and Quantization - gives an overview over the sampling theorem, aliasing, quantization noise and dynamic range of digital signal processing system
Stereo Processing - discusses various aspects that arise specifically in the context of stereo signals such as correlation, stereo-width, mono-compatibility, mid/side-processing and stereoization
Waveshaping - explains the signal processing technique of waveshaping which is the basic technique for nonlinear distortion (or simply distortion) devices
