Day 2 of the TI developers conferene promises to be just as big as the first day. I have a full day of audio in front of me, and I've already met with several TIers involved with audio technology.
Fellow CMP Editor Bill Schweber, Editor of PlanetAnalog sent me a news article that discusses the decline in consumer audio quality. The e-mail came at an ironic time. I talked to a fair number of audio designers yesterday, and a TI rep today. There seems to be a universal agreement that quantity of songs trumps the quality of what is played. As one engineer said "I don't care about the loss of quality. MP3 is good enough, and I want to carry my colletion with me."
I believe that the trade-off will change as more capable codecs are introduced and become widely available. But the essential message is that audio isn't always about getting the most quality. Today it's about noise levels, battery life, and the number of minutesos play time available.
Finding out the perceived frequency response of your combined headphone/ear 'system' and compensating for it using parametric equalization can offer some eye-opening benefits. But finding an EQ solution isn't always easy.
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.
