okiejonwilliamson Show HN: Intentionally subtle headphone crossfeed filter

One example is the Roland CS-10EM microphones/earphones. A pair is $99 on Amazon.

In-ear binaural microphones can be used to reproduce in with headphones what a listener hears during a live performance.

okiejonwilliamson Show HN: Intentionally subtle headphone crossfeed filter

The most accurate way to make a stereo recording sound like it's coming from two speakers when listening with headphones is to use the head-related transfer function (HRTF), which phases and filters audio sources in a virtual 3-D space in the same way that their positions, the human head, and ears do. When waves pass through the head and ears from different directions, the loudness and frequency content is changed before it reaches the sensors in the inner ear.

okiejonwilliamson Ask HN: Freelancer? Seeking freelancer? (March 2014)

I'm interested in exciting freelancing opportunities. I'm an electrical engineer/hardware developer. I love power and analog electronics, digital design, and the occasional DSP or micro-controller challenge. I have experience with Bluetooth, battery-powered, mobile, USB, ~500W audio power amp, low-noise and high-speed analog and digital, AC/DC, sensors, MEMS, control, actuators, high-voltage, tiny, low-power, turn-key PCB manufacturing and assembly, SolidWorks integration with mechanicals, human interaction. I enjoy writing Python, C, Mathematica, and MATLAB code.

SCIENCE.

okiejonwilliamson Scientist banned from revealing codes used to start luxury cars

"The scientists said it had probably used a technique called "chip slicing" which involves analysing a chip under a microscope and taking it to pieces and inferring the algorithm from the arrangement of the microscopic transistors on the chip itself – a process that costs around £50,000."

£50,000?! Good Lord, that's a lot of money! All one needs is a microscope and a razor.

Primer.

It's about some engineers who burn the midnight oil on their side-project, a start-up, and sort of accidentally discover something amazing.

"If you ditch work this afternoon, and promise to do the few small things I ask you; I will in return show you the most important thing that any living organism has ever witnessed."
