Examining the Oscillator Waveform Animation Effect

An enhancing effect that can be applied to analogue oscillators in subtractive synthesizers is termed Animation, which is an efficient way to create a sound of many closely detuned oscillators playing in unison. This is often referred to as a supersaw oscillator. This paper first explains the operating principle of this effect using a combination of additive and frequency modulation synthesis. The Fourier series will be derived and results will be presented to demonstrate its accuracy. This will then provide new insights into how other more general waveform animation processors can be designed

Phaseshaping oscillator algorithms for musical sound synthesis

This paper focuses on phaseshaping techniques and their relation to classical abstract synthesis methods. Elementary polynomial and geometric phaseshapers, such as those based on the modulo operation and linear transformations, are investigated. They are then applied to the generation of classic and novel oscillator effects by using nested phaseshaping compositions. New oscillator algorithms introduced in this paper include single-oscillator hard sync, triangle modulation, efficient supersaw simulation, and sinusoidal waveshape modulation effects. The digital waveforms produced with phaseshaping techniques are generally discontinuous, which leads to aliasing artifacts. Aliasing can be effectively reduced by modifying samples around each discontinuity using the previously proposed polynomial bandlimited step function (polyBLEP) method

Synthesis of Resonant Sounds with a Heterodyne Model

This paper considers the generation of resonant waveforms from a number of perspectives. Commencing with the well-known source filter model it introduces a more advantageous heterodyne interpretation. Some variations on the basic design and comparisons with previous methods are then given. An analysis on the use of three different digital music filter structures for resonance synthesis is made, followed by an example showing how timbrally rich Frequency Modulated resonant waveforms can be synthesized

Soft Sound: A Guide to the Tools and Techniques of Software Synthesis

“Soft Sound” is an examination of software synthesis, the act of using computer software to create audio signals from scratch. It begins with the basics of sound, a prerequisite for understanding any form of synthesis. Then, it delves into a quick history of analog and digital synthesizers before jumping into the heart of the paper: a look at the forms of synthesis that are commonly done in software rather than analog hardware. These forms include wavetable modulation, frequency modulation, and granular synthesis. Different environments for implementing such techniques will be discussed, ranging from user-friendly virtual synthesizers to low-level programming environments. The paper draws material from a variety of sources ranging from books on computers and music to manufacturer manuals and online magazines. Ultimately, it will be argued that the computer has revolutionized music creation by providing an affordable and convenient way to realize a virtually infinite number of sounds

Digital Emulation of Distortion Effects by Wave and Phase Shaping Methods

This paper will consider wave and phase signal shaping techniques for the digital emulation of distortion effect processing. We examine in detail how to determine the wave and phase shaping functions with harmonic amplitude data only first, and then after including the harmonic phase data. Three distortion effects units are used to provide test data. Wave and phase shaping functions for the emulation of these effects are derived with the assistance of a super-resolution frequency-domain analysis technique. In complement to this, we describe an alternative time domain method for determining phase shaping functions using Dynamic Time Warping. Finally, we propose a method for assessing the frequency dependency of distortion effects to help the design of multiband wave and phase shaping functions
