Well, not technically away, but between Pandemic’ng, releasing Pro Display XDR (based on my EDR technology), Apple Silicon based Macs, introducing EDR to the World at WWDC, and some other things I can’t talk about quite yet, I haven’t had time to share things audio here 🙁 However there is news to belatedly announce! AudioAnecdotes […]

Great Visualization of Fourier Transform
Grant Sanderson AKA 3blue1brown posted a great video visualization of the Fourier Transform. I would have loved to have encountered this when I first began exploring its mysteries in the 1980’s (when I could only find droll texts on the subject)! Grant visually explores decomposition, winding, motivations for use of the complex plane, and the inverse […]

‘Here’ no evil
I am very disappointed to learn of the dissolution of Doppler Labs and the discontinuation of their Dubs passive hearing protectors and highly innovative active Here One bluetooth ear buds. Doppler created a new product category for a consumer product designed to augment normal people’s hearing. To pull this off requires solving many audio engineering challenges […]
Schlieman Flow Visualization of actual sound waves
We have all seen sound waves visualized on oscilloscope or even spectrum analyzer screens, but how often have we seen actual photographs, or even better video, of the three dimensional compression and rarefaction that is sound propagating in the real world? NPR’s skunk bear has a great video both demonstrating and explaining Schlieman flow visualization […]

Entrainment (for the New Year)
I just saw Ikeguchi Lab’s awesome demonstration of 100 metronomes becoming synchronized via mutual entrainment (the metronomes are arrayed on a hanging platform to facilitate) and thought this was just the thing to share as we say farewell to 2016 and look forward to 2017. Let’s collectively make 2017 a healthy, happy, safe, and prosperous […]

Had a good if commercial Maker Faire
I have a bit of an odd relationship with Maker Faire. I love the great people behind the Faire at Make Magazine/O’Reilly (and hope their recent troubles have been overcome), and the Makers themselves; am amazed by the tremendous community support as countless thousands attend Maker events, now around the world, with their children, the next […]

Regretfully I won’t be hosting a booth again this year at Bay Area Maker Faire 2016 but I will be attending and would to see and hear from you all. Let me know where you will be and what you are most excited about!

Bluetooth over MIDI
The Moog Model 15 Modular Synthesizer app has me looking for a Bluetooth over MIDI solution (Apple incorporates native MIDI over Bluetooth LE support in iOS9: spec, tech note for app developers). I want to skip over the kludgey USB-MIDI-Camera Connection dongle stack to interface my old Roland keyboard to the iPad (replacing the ancient Yamaha […]
