Closed-Loop Audio Tuning for Cars

When you look at high-end home audio, the concept of 'room tuning' becomes important in order to create the best listening experience. This is usually done by hand, iteratively, and by experts with years of experience. This process looks includes modifying the placement of components as well as the listening position, and can also involve adding devices designed to modify the acoustic response of the room.

As you can imagine, the 'room' that is the interior of a car presents a much tougher challenge. As such, the quality of any car stereo is a massive compromise to the geometry of the cabin. But a new technology in sonic profiling looks to address this issue. By using an in-line signal processor, this invention modifies the source signal based on a set of closed-loop tests run in the vehicle. The result is an optimized reproduction of the original signal. Pretty neat; I'd love to check this out myself.

OnLive Latency Discussed

So OnLive is buzzing like crazy. I understand it a bit more now: instead of running the game on your local PC, it's rendered on a remote machine and the video is streamed to your PC. There's a lot of technology that supposedly addresses the latency issue associated with the network, but it's yet to be tested in the real world. But if it works...it could dramatically change the face of console and PC gaming.

When Innovation Meets 'Duh!'

Man, how long did it take to stumble upon the idea of using wasted hot water to heat incoming cold water. The result is a 40% increase in efficiency. Wow.
