Clockworks and Audio Builders Workshop (ABW, a working group of the Boston chapter of the Audio Engineering Society) created a simple Metronome project for people interested in building their own audio electronics. It’s intended as an entry level project for anyone interested in learning about building electronics kits. ABW has “build events” where the parts […]
This post is one of three related to the work done to measure resistor excess noise. A summary writeup and three other documents with experimental detail are provided to those interested in performing their own experiments. These long form reports were summarized in to AES eBrief 486 (open access), presented at AES 145 (Oct 2018, NY, NY).

From the presentation at the Boston AES meeting held 27-Feb-18 at Shillman Hall, Northeastern University, Boston, MA. In addition to being a technical presentation aimed at anyone involved with audio, it also served as an example for students interested in submitting papers to upcoming AES events.

As part of an ongoing investigation in to excess noise (also called 1/f noise) from resistors I recorded some data taken with the AP515 and posting it here. All 3 tracks have 80 dB of gain added to them using Audacity. The actual signal level from the resistor is a few microvolts. The part being […]
