Photosynth Demo

This is nothing to do with audio, but I had to include it in this Blog as it is extremely impressive:

Quote: "Using photos of oft-snapped subjects (like Notre Dame) scraped from around the Web, Photosynth (based on Seadragon technology) creates breathtaking multidimensional spaces with zoom and navigation features that outstrip all expectation. Its architect, Blaise Aguera y Arcas, shows it off in this standing-ovation demo. Curious about that speck in corner? Dive into a freefall and watch as the speck becomes a gargoyle. With an unpleasant grimace. And an ant-sized chip in its lower left molar. "Perhaps the most amazing demo I've seen this year," wrote Ethan Zuckerman, after TED2007. Indeed, Photosynth might utterly transform the way we manipulate and experience digital images."

Reverbent Office - update 1

One of the prototype absorption panels was tested in the office space today. However, at 3m tall by 2m wide, it was a little on the large side. On the plus side, a very noticeable reduction in reverb time was observed and so now, after some detailed calculations using the Sabine formula and assuming a nominal frequency of 1kHz, it has now been decided to make 12 1200 x 600 panels based on the same design as in the previous post. Assuming the maths is correct, the calculated RT60 time of 1.65s should be reduced to around 0.65s with the panels in place; Howard (2006), states that this is an ideal figure for speech.
