I am finding this series a useful recap. Although I started in pro-audio I was seduced by embedded processors and digital video, but audio was definitely my first love - it's so damn analog! The thrill was that to achieve barely acceptable SNRs of -94dB when working with 26dB of headroom took everything we had - the best brains, the best parts and then some. But we did it, and othing much has changed in terms of the net quality delivered, especially in a digital world where we can mix at 96kHz and 24 to 96bits if we want but the compression artefacts in the listeners' source material will reduce the SNR to 12 bits, or worse if we include class H amplification side-effects. Hopefully the incease in available bandwidth will increase the amount of releases on 16bit linear PCM source, just to get rid of that quantisation weebling and psychacoustic algorithmic breathing! Hifis still can't reproduce a piano in full voice, let alone a drum kit - maybe a good system a Marshall stack heard from way off.

LATEST ARCHIVED BROADCAST
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.
