It's interesting that the whole phase linearity thing came and went in the late 70s. Recently the "big thing" is frequency response customization. Most high end recievers have Audyssey (you set specially calibrated microphones in the primary listening areas)MultiEQ room calibration or equivalent to take care of room characteristics, but generally at the cost of phase linearity. There's no denying that it sounds great, by my 1977 vintage phase linear speakers still have the effect of turning your head to see if it's real or not, particularly with brass and drums...

Brands of loudspeakers are recognisable by their characteristics, in one case in my experience by their lack of charateristics - I once walked past a London shop doorway and for a second or two felt a bubble of clear sound round my head as I passed; sure enough, at the back of the store was a Tannoy 15in monitor pointing outward. Its outstanding phase-coherence provides a unique and (sadly) unusual experience. As the author points out here, however, room placement and loudspeaker format interact hugely in making the LS more or less sensitive to listener position and movement, and any improvement through this work will be welcomed by audiophiles everywhere.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
