PADsynth is a synthesis technique that generates a lush sound with a simple algorithm. The algorithm begins with additive synthesis, where you build a timbre with a sine wave at the fundamental and each overtone. A frequency magnitude plot of this would show several thin spikes. PADsynth adds a twist. You can make the sound [...]
This is a simple acoustic beam steering simulation built in Processing/Java. The simulation has physical correspondence; it runs at 1/2000th realtime and at a scale of 10 pixels = 1 meter. The array size is fixed at 2.5 meters (25 pixels tall), positioned at the left edge of the display region. More at HRTF and [...]
Re: Digsby Blog - Striving for Perfection No Gtalk File Transfer = No Perfection. In order to revolutionize chat, Digsby must create a working file transfer solution for Gtalk. Trillian, Meebo, Adium. Many have attempted and many have Failed to answer the call for cross-protocol Instant File Sharing. Some more miserably than others. Whoever can [...]
The first batch of 25 speakers for the WFS array has arrived. These will go into a mini-array configuration for testing nearfield listening. I bought these 4 ohm, 2" drivers from a distributor that happens to be in southern Florida.
If you surround a listener with a great sphere of loudspeakers at a fixed distance, it should be trivial to produce a virtual source at any direction. What isn't trivial is producing a virtual source at an arbitrary distance, since the loudspeaker positions are fixed at a given distance from the listener. It could be [...]
