So years ago in grad school at UNM, I worked on audio localization. My work was on the idea of doing the convolution (applying the filter to the audio) in the wavelet domain, to extend the results from a phd student in the group. My results were poor, read about them on this page.
The reviews are mixed, but the really impressive part is less obvious – you use your phone camera and it uses photogrammetry to derive the geometry of your head and pinnae, and from that it creates a personal HRTF that it loads into the finger-sized gadget:
I’m sorely tempted to buy one just to see how well it works. At $160 is a bit much for an impulse buy though.
It’s really cool to see similar work, with a big chunk of progress plus some really new and clever ideas added. This version is USB, so Android/desktop, but they do have a Bluetooth version in the works that’d work with my phone.
Saw this cool old car the other day and realized that, although the style is cool, I am so not interested in the hassle of and old gas engine. EV really has made a convert out of me.
