Back Emf Phase Relationships In Moving- Coil Loudspeakers (Part 3)
In the third article in this series, we discuss the concept of slip, in order to explain how and why it causes the impedance to be inductive, resistive, or capacitive, depending on frequency.
What Was That Masked Sound Anyway?
In this article, Richard Honeycutt explains the process of sound masking, how it is used, and ways that it can occur unintentionally.
Thoughts On AES X223 And X241 Speaker Measurement Projects
I have just returned from the recent Audio Engineering Society (AES) 144th International Convention in Milan, Italy, where I was among many colleagues who are trying to solve one of the outstanding problems of loudspeaker drive units today. Namely, being able to trust the measurements that are being presented to us.
Stereo Listening - Acoustics, Electroacoustics, And Pychoacoustics
Our experience of sound is necessarily subjective, but knowing the history of the science of stereophonic sound can help us to make intelligent decisions about our listening spaces and equipment.
MPEG-H Audio Brings New Dimensions To Tv Sound
Fraunhofer Institute for Integrated Circuits IIS designed a way to significantly improve immersive sound reproduction capabilities on consumer playback devices, based on MPEG-H decoding and rendering and Fraunhofer’s upHear soundbar processing. This article is a technology update on MPEG-H and Fraunhofer upHear implementations, now available for licensing to audio video receiver (AVR) and soundbar manufacturers.
Exploring Master Quality Authenticated (Part 1) - Measuring The Difference
By now, I expect every music enthusiast has heard about Master Quality Authenticated (MQA) and how the high-frequency content is folded, origami fashion, into the low-frequency region. An MQA decoder (DAC) unfolds the highs back to their proper spectral location. The theory sounds great but because we can’t directly hear this upper register, how do we know what’s actually there?
