Also on the cutting-edge of current audio industry trends, Jon Schorah, Creative Director, Nugen Audio, discusses “Mixing and Mastering for Today's Music Streaming Services,” and explains what you should know about delivering music to Spotify, Apple Music, TIDAL, and other platforms.
This month, we also bring you a very interesting article providing an expert perspective by Ofer Elyakim, Chief Executive Officer, DSP Group, on “Engineering Voice-Enabled Smart Gadgets.” As one of the leading vendors in semiconductor solutions with an extensive experience in enabling voice a variety of new consumer electronics devices, using its open audio/voice DSP platform, Elyakim discusses how DSP Group addresses solutions for implementing voice user interface (VUI) experiences.
And with Master Quality Authenticated (MQA) streaming the focus of the industry's attention, this month Ron Tipton continues his measurement experiments and shares what he learned after playing a few MQA tracks from Tidal's music streaming service. He also confirms how MQA high-resolution audio files can be played directly from a newly release CD already supporting the format.
Our interview this month is with Robert Oliveira, the founder of Hearing Components, responsible for inventing the Comply Foam special memory foam tips that have improved the experience of using in-ear headphones for millions of consumers globally. A serial inventor and biochemist, Robert Oliveira worked at 3M for 18 years, developing products ranging from biochemical diagnostics to surgical instruments. An ear canal expert, he also led a 3M team that developed the world’s first FDA-approved cochlear implant.
And for our DIYers, one of our regular contributors and audio electronics expert George Ntanavaras explains how to build a turntable speed measurement device using a microprocessor-controlled device that measures the speed of a turntable's platter. The project is based on the Arduino Uno hardware board and the Arduino software IDE, and uses a micro sensor manufactured by Omron to sense the platter rotation.
Continuing his discussion on "Back EMF Phase Relationships in Moving Coil Loudspeakers," Andy Lewis details some experiments to better understand the phenomena. Having noted that, in a loudspeaker, there are three modes of Back EMF generation - below, at, and above resonance - inductive, resistive, or capacitive, respectively - he now performs simple “thought experiments,” in order to make qualitative observations about the activity of a moving-coil driver in the region of its resonance.
In his Sound Control column, Richard Honeycutt writes about Stereo Listening. In this article he covers the topic from the acoustical, electroacoustical, and pychoacoustical perspective, because as he writes, "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."

Finally, in his column about everything tubes, Honeycutt writes about “The Evolution of Tone Controls in Tube Amplifiers.”
