Dear Brent, I am surprised to see the wrong perception, among the audio engineers and audio experts/reviewers, about the IR technology. Infra-com has developed a chip-set for wireless audio using Diffused IR (non-line-of-sight) and it is fully digital (PCM) - supporting up to 4 channels at 24Bit audio quality at sampling rate 44.1Khz or 48Khz with no compression. Please feel free to contact me for further details: ellias@infra-com.com, or visit www.infra-com.com. It is true that the 'old' IR technology (i.e. based on carrier modulation) which is analog technique and is dominating the IR audio in the consumer market. I think the same same can be said also about audio applications using RF technology at the 2.4GHz ISM band - which is compressed and is susceptible to interference from other RF Sources at the congested 2.4GHz ISM band. Perhaps this information can contribute some enlightenment on the IR technology. And perhaps to update your article to correct your misconceptions about IR technology. Thank you. Regards, Ellias Attias

Have anyone used IR for wireless audio distribution before?

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.
