Standardized Automotive Audio Measurements

In 2023, the Audio Engineering Society (AES) Technical Committee on Automotive Audio proposed a standardized measurement configuration for in-car audio systems. This article builds on that work, using the same configuration to make a more comprehensive suite of measurements, including seat-to-seat spectral uniformity, THD, advanced impulsive distortion, as well as creating a foundation for a much wider range of in-car measurements.

Linearizing Microphones: CORE+ by DPA

Linearizing Microphones: CORE+ by DPA

This article is an exclusive report on the development of the DPA CORE+ technology at the heart of DPA's miniature microphones. Evolving over the previous CORE technology that dramatically enhanced the dynamic range of the microphones, the patent-pending CORE+ by DPA eliminates the non-linearities typically generated by the membrane and electronic components, removing any trace of distortion from the microphone output, and improving even on the already extremely high standards of the Danish manufacturer.

Cirrus Logic and Compal Electronics Join Forces to Pioneer AI-Powered Audio Enhancement for Laptops

Cirrus Logic announced a strategic collaboration with Compal Electronics from Taiwan to develop AI technology aimed at solving persistent audio quality challenges in laptop computers. The partnership will leverage Cirrus Logic's expertise in audio processing and Compal's design and manufacturing experience to address mechanical rattle and audio distortion issues that have long plagued the PC industry. This initiative represents Cirrus Logic's first AI audio technology designed specifically for the PC market.

Non-Linear Amplitude Modulation of Loudspeakers

Non-Linear Amplitude Modulation of Loudspeakers

Even a perfectly linear loudspeaker produces two types of distortions because of the movement of its membrane. First Doppler distortions, a.k.a. Phase Modulation (which the author addressed in his October 2024 article for audioXpress), and secondly distortions stemming from the Nonlinear Amplitude Modulation, characterized in this article. More importantly, this article also addresses how these harmonic and intermodulation spectral line distortions can be minimized and eliminated in loudspeakers.

DPA Unveils Latest CORE+ Patent-Pending Microphone Innovation

DPA Microphones announced its new patent-pending CORE+ technology that the Danish manufacturer says sets a new standard for distortion-free microphone sound. Touted as a groundbreaking innovation, DPA says that CORE+ eliminates the non-linearities typically generated by the membrane and electronic components of a microphone to redefine what’s possible in sound capture. The technology was unveiled at NAMM 2025 and will be presented also at ISE 2025.

Audio Electronics: Is Digital Jitter Really a Problem?

Audio Electronics: Is Digital Jitter Really a Problem?

Since the dawn of the digital era decades ago, the timing error known as "jitter" in A/D/A converters has been accused of harming audio fidelity. Some people claim that jitter adds audible distortion and noise, affects bass fullness, and even harms stereo imaging width and depth. This article explains what jitter is, what causes it, and even lets you hear jitter in controlled amounts so you can decide for yourself how damaging it really is. Originally published in audioXpress, January 2024.

Selecting Electrolytic Capacitors for Lowest Distortion

Selecting Electrolytic Capacitors for Lowest Distortion

Douglas Self shares real experiments when selecting electrolytic capacitors to achieve the lowest distortion. An experiment inspired by his recent audioXpress article, "Optimizing Variable-Frequency Tone Controls," available online. This short piece is an interesting closer examination on the subject for audio circuit designers. Originally published in The Audio Voice newsletter, #453, January 11, 2024.

Audio Myths: Feedback Re-Entrant Distortion. Should We Worry?

Audio Myths: Feedback Re-Entrant Distortion. Should We Worry?

There are many aspects of negative feedback in audio that are the subject of continued discussion. Jan Didden continues to debunk more Audio Myths. This article addresses re-entrant distortion. The idea is that, since negative feedback sends some of the distorted output signal back to the input, this already-distorted signal would only get more distorted by going through the nonlinear amplifier, over and over again.
