This 6 part series of articles examine some of the important principles, possibilities, and limitations of wireless systems.

CORE by DPA and CORE+ are powerful technologies at the heart of DPA miniature microphones. Learn more about why CORE/CORE+ is important and why mics with them sound better.

The waveform of an audio signal exhibits a positive segment above the zero line and a negative segment below. Sometimes the waveform looks symmetrical and other times asymmetrical. Usually, the waveform’s shape and polarity doesn’t matter until we begin to mix the signals, i.e., when we have signals from two (or more) microphones that we want to combine or perhaps distribute for spatial imaging. Then, it is important to understand the terms polarity, phase and delay. This article describes the three terms with regard to microphone techniques and technology.
