Audio THD with QSPICE: An Interview with Mike Engelhardt

The creator of LTspice has designed a new and much improved simulation tool suite called QSPICE (the Q is for Qorvo, the company that supported the new effort). Mike Engelhardt, physicist, analog engineer, and entrepreneur talked to Tim McCune, former president of Linear Systems, to discuss how QSPICE can help solve many issues that audio designers simulating their circuits might confront.

Enhancing Loudspeaker Efficiency and Bl(x) Symmetry with Virtual Voice Coil, Part 2

Enhancing Loudspeaker Efficiency and Bl(x) Symmetry with Virtual Voice Coil, Part 2

This is the second article detailing the design and simulation possibilities of the SpeakerLAB software and its Virtual Voice Coil (VVC) module for speaker designers. This simulation includes complete temperature management involved in loudspeaker calculus. The article also expands on audio transducer parameter prediction such as maximum SPL, analyzes key design components such as the magnetic circuit, and analyses the resulting simulated metrics that could help determine the highest efficiency.

EASE 5 Third Edition Redefines Sound Reinforcement Planning with Acousteer Real-Time Simulation Engine

Discreetly introduced at the end of 2024 by Berlin-based AFMG Technologies, the Third Edition of EASE 5 updates this universal planning tool for loudspeaker systems with a real-time simulation engine called Acousteer. The new processing architecture allows users to calculate audience area mappings in milliseconds, with real-time adjustments, shifting the process from iterative to a dynamic exploration. The EASE 5 Third Edition suite not only empowers users to design sound systems with unprecedented accuracy, but also introduces the possibility to calibrate models accurately and collaborate live with other users and stakeholders.

Simulation Techniques: Perturbation Methods in Audio Engineering

Standard simulations are closely tied to the analytical framework much more than the numerical. Simulation software gives insight into physical products that could not be achieved otherwise, often leading to less attention being paid to analytical methods and descriptive mathematical expressions related to the physical application. This article explores an analytical approximation method described as a perturbation approach.
