+Cyanogen offered me an incredible opportunity to continue working on displays and audio, but at a larger scale

I'm honored +Android Police +Michael Crider cared about interviewing me.

Yesterday I flooded Michael for hours with details and explanations.
Talking about projects I'm working on with passion to improve user experience on mobile in very specific areas.
Kudos to him for managing to write an article out of it 🙂

I just started at +Cyanogen so there's a lot to learn. I'll do my best to transform R&D into concrete products, and there's no other place to make this real in connection with the developer community and a large and enthusiastic users base.

Feel free to drop any question, I'll do my best to answer here with what I know.

There's some great stuff in here for audiophiles and videophiles. Thanks to +François Simond for the interview!

Making progress on the color space implementation in my colorimeter measurements & calibration app!

After rewriting all the color space conversion code now using as input only:
– the primaries xy coordinates
– white point / illuminant XYZ coordinates
– an opto electronic conversion function (aka gamma)
– optionally fixed black and white point values
Here's a few examples of various color spaces presets I added to stress test the math and conversion matrices generated, by simulating measurements of a display rendering them perfectly each one.

All good 🙂

I posted the kernel source for +Raspberry Pi with +Wolfson Microelectronics beta driver patches for the Wolfson Audio Card applied as a git repository, so you don't need to do it yourself ;)

Note that for now it's only the source code obtained following original +Wolfson Microelectronics pdf guide from Andy Laing here:
http://www.element14.com/community/thread/31714/l/instructions-for-compiling-the-wolfson-audio-card-kernel-drivers-and-supported-use-cases

+Wolfson Microelectronics patches have conflicts with latest repository state. I didn't tried to merge latest commits for now but let me know if you do!

A +Samsung Mobile Galaxy S5 Exynos teardown reveals +Wolfson Microelectronics WM5110 Quad core HD audio processor SoC

WM5102 and WM5102s announce higher DAC & headphone amp specs but the WM5110 has a much higher compute capability and also better ADC.
Think about: decoding and playing compressed audio streams while the system sleep; stuff like that.
You can take a look at apparently leaked product briefs linked.

Today I'm excited because the work I did yesterday should now allow me to generate calibration profiles targeting any white point

Previously, my calibration algorithm was supporting only sRGB / Rec. 709 white point D65, of about 6500K.

At home I have two Dell UltraSharp 2407WFP giving me the hardest time to measure and calibrate.
Somehow, their aging CCFL backlight is throwing off every spectro or colorimeter sensor I tried and targeting a D65 white point from the measurements obtained only give a terrible blueish/pinking hue.
Added to that, some kind of dithering or backlight PWM on those displays trips off the X-Rite i1 Display Pro 3 using Argyll as a driver.
Super fast colorimeter; maybe a bit too fast in this context !

Color balance being off should not happen using the spectro measurements, as XYZ readings are not coming from a RGB-filtered light sensor but instead wavelength domain sampling.
But the spectro I have is an old EFI ES-1000 bought used for a cheap price and on this particular display the results are in contradiction with what you can perceive with your own eyes.

With this new math & code, I should be able soon to calibrate those desktop monitors I spend so much time behind.
I look forward to get here as the results of my algorithm surpass by a fair margin in accuracy every other I tried so far.
