Abstract:
This talk discusses the techniques used to simulate analog audio effects in real-time, such as guitar amplifiers, studio effects, or synthesizer filters. First, a summary of the various techniques available nowadays to develop "virtual analog audio effects" is presented. We will see that the modeling process can be divided into the following steps : modeling of the electronic components of interest, study and simplification of the electronic schematic, derivation of the equations, discretization, simulation, optimization, comparison of the simulation with the reality and improvement of all the previous steps. Second, very concrete applications of the principles seen previously are presented. A few simple circuits are studied, from the modeling to the simulation, with details about the librairies that might be used and good practices to improve the efficiency of the simulation and to keep the CPU consumption as low as possible. Finally, some virtual analog audio effects made with JUCE are shown to the audience, which will be released on the internet with their source code and the Projucer files by their author.
About Ivan Cohen
Ivan Cohen is a freelance software developer from France, with an extensive experience in the audio software industry. He did a PhD thesis with the IRCAM and the company Two Notes about guitar amplifiers simulation from 2009 to 2012, and he has developed audio effects for a few companies such as Sonic Academy, Audionamix, TSE or Two Notes, mainly with the VST SDK and the JUCE framework. Today, he is looking for opportunities to work with other companies on audio effects technologies, and he is going to release his own products, under the brand name Musical Entropy.
