With the furor over the launch of DAT (digital audio tape), it is worth remembering that commercial digital recorders have been with us for some time now: it is now nearly a decade since studio PCM converters were first successfully used for audio recording in conjunction with a VCR (which uses a helical spiral recording via a spinning drum to achieve the high writing speed).

In her reworking of the Beatles' "With a Little Help from my Friends," on the 2018 tribute album, A Day In The Life: Impressions Of Pepper (impulse records), Brooklyn guitarist and composer Mary Halvorson reinvents both her instrument and the song.

Most baby boomers can hum the tune of the Beatles' classic, from Sgt. Pepper's Lonely Hearts Club Band, in a handful of notes. It might take longer to recognize Halvorson's joyous, angular version. A master of jazz phrasing, guitar technique, avant-garde discourse, and effects pedals, Halvorson bends the Beatles song to her 21st century will.

Lately, there's been too much gear worth covering and not enough space to cover it in. So this time . . . less think-piece filler and more hardware!

Shunyata Research is the brainchild of Caelin Gabriel, whose résumé includes stints at NSA, in military R&D, and in the computer industry, first digging weak signals out of noise then developing very high-speed network devices. He is also a lifelong audiophile.

Shunyata's roots are in the scientific understanding and engineering base Gabriel has developed during his career. I've long been impressed by those scientific underpinnings—which extend not only in audio but also to other fields including medical devices—and by how open the company is in talking about its technologies.
