Simulation Techniques: Misconceptions in the Audio Industry

In this fascinating article about common sound theory misconceptions that exist in the audio and hifi communities, René Christensen debunks three of them. Starting with group delay and phase delay, what actually happens when a loudspeaker driver moves outward and inward, and the effects of polarity and phase flip. True reference material with detailed mathematical expressions and numerical analysis. This article was originally published in audioXpress, June 2023.

Sound Particles, the innovative audio technology software house is not stopping its pace of development. While its core particles sound design software is being used in almost all movie blockbusters, including the latest Indiana Jones or Mission Impossible, the Portuguese company now announced the launch of AudioMatrix, an audio routing utility plugin designed to empower all audio professionals working with complex multichannel content for immersive formats.

For all the audio professionals that are confined to working from home or working on a limited basis, Studio Six Digital has announced that it is cutting the price of its AudioTools app in half, and reducing the in-app Full Module upgrades by 1/3. To see the special pricing, which will depend on what users have already purchased, you just have to open AudioTools and go to the Support & Upgrades menu, AudioTools Store.

KRK Systems, (still) part of the Gibson family of brands, introduced its new KRK Audio Tools App for iOS and Android. The free suite of professional studio tools includes five useful and professional analysis-based components that work with any monitor setup, and one powerful tool (EQ Recommendation) that helps acclimate the new KRK ROKIT G4 monitors to their individual acoustic environment.

Is the solid part of a loudspeaker motor just a magnet or is there more to it? Simulation tools have helped to create effective and powerful magnet constructions, which make it easy to build a prototype based on calculations and experience. The next obvious step is measuring and listening to the assembled speaker. However, more conclusions can be drawn by analyzing the individual parts further.
