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.

The July 2025 issue of audioXpress includes the AXPONA 2025 Show Report, a review of the Illusonic IAP 8 multichannel audio processor and preamplifier, and an interesting audio processing exploration of Beat Tracking. DPA Microphones shares its CORE+ technology research, and René Christensen offers a deep dive on Microacoustics Modeling. Finally, David B. Soffer explains how to build an Audio Amplifier Power Meter using Arduino, and Richard Honeycutt writes about low frequency annoyance.
