xoxos has released fauna, a VSTi which emulates animal vocalisations by inducing oscillation as a function of structure instead of processing a source oscillator.
fauna is an elementary application of the kelly-lochbaum tract in conjunction with a simple reed model.
The kelly-lochbaum vocal tract employs a series of coefficients representing open area of the vocal tract to compute transmission.
The length of the tract is divided into five sections, or waveguides. these waveguides function as conventional delays set to very short times to model the acoustic transmission through air.
xoxos explains fauna with a pretty illustration.
The low waveguide count allows a variety of animal sounds to be mimiced to some degree at a low cpu expenditure.
The glottis functions as a valve, opening with pressure from the lungs and closing with pressure returning from the mouth. The smaller the aperture, the higher the reflection.
The throat of the tract is tapped separately and passed through a resonant low pass filter to add throat or body resonances. These are key components of some tones. The signal at the throat is generally less detailed than the mouth output.
The final stage of the signal chain is a 6db high pass filter, which can indicate size and proximity of the source.
fauna is freeware and can be downloaded here.
2008-02-06: Fauna is now released as donationware. A demo version is available for download (demo has 16 patches, paid version has 107).

Some interesting things I bookmarked on del.icio.us on October 4th, 2007:
- Chilli-based anaesthetic won’t leave you drooling – Clifford Woolf and his colleagues at Harvard Medical School have discovered a way of blocking just the pain neurons using capsaicin – the active ingredient in chilli peppers – along with a version of lignocaine that can’t diffuse through cell membranes unassisted.
- Big Daddy Hands – The bigger version of the soldering tool, useful for holding more than a small circuit board.
- InfraRecorder – a free CD/DVD burning solution for Microsoft Windows. It offers a wide range of powerful features; all through an easy to use application interface and Windows Explorer integration.
- Sketch Furniture by FRONT – Pen strokes made in the air are recorded with Motion Capture and become 3D digital files; these are then materialised through Rapid Prototyping into real pieces of furniture.
- Mustaches of the Nineteenth Century – A Daily Celebration of The Golden Age of Upper Lip Hair.
- Ryan McLennan – Beautiful acrylic on paper paintings of wildlife.
- Mike Leavitt – Action Figures – These are articulating, miniature, interactive sculptures, aka. “action figures” or “toys”, each hand-sculpted with synthetic polymer clay, wood and elastic by Leavitt.
I Heart Tripods is a remarkable site by Sonia Zjawinski, whose dog Lulu suffered bone cancer and had to undergo amputation of her left hind leg. After all the procedures (surgery and chemo treatment) Sonia had bills to pay, $10,000 worth of bills…
I put everything on my credit cards without thinking twice, but once the bills starting coming in I realized I needed a plan. I asked my awesome friend Eric Siry to design a logo to put on T-Shirts and tote bags. The goal was to eliminate my debt; the dream was to make more than I need in order to help other animals and their owners who cannot afford expensive procedures and treatments. We’ve reached our dream! But now we’re looking to sell even more shirts so we can start handing out checks to those in need. Buy something from the tripod store and show your support for all animals — four, three, two, and even one-legged!

So, if you want to support this cool project, just head on over to the Tripod store and buy something.

Pink Tentacle reports about a video clip from Trivia no Izumi, in which you can see how frogs cope with severe indigestion.
After a disagreeable meal, a frog can empty its stomach by ejecting the entire organ inside-out through its mouth and washing it with its front legs before swallowing it back down.
Frog throws up his own stomach
The host of the show explains that a frog throws up in much the same way that humans do, but its stomach pops out because of its relatively wide and soft esophagus. Incidentally, some people believe frogs are right-handed because the ejected stomach protrudes to the right and they mainly use their right front leg to wash it.
Paul Middlewick discovered an elephant on the London Underground map during his daily journey to work.
From Animals on the Underground:
The Animals, made up using tube lines, stations and junctions on the London Underground map were spotted by Paul Middlewick some 17 years ago. The original Animal, the Elephant was discovered while Paul was staring at the tube map during his daily journey to work.
Since then, the Elephant has been joined by many other Animal friends.

World leaders are urged to end tiger trade at the unveiling of the world’s largest tiger photo mosaic.
Tiger mosiac – zoomed in detail
A two-storey-high photo mosaic of a tiger, created from personal photos of nearly 25,000 tiger lovers worldwide, was unveiled in The Hague, Netherlands on 7 June, to urge world leaders to end all trade in tigers. Individuals from more than 140 countries contributed their pictures.
Read more about the “End the Tiger Trade” campaign here. You can still submit your photo to become part of the massive tiger mosaic and call for an end to the tiger trade.
If you’ve ever seen National Geographic’s Crittercam you might already have an idea what this is about.
J. Perthold has made a CatCam, to track the adventures of his cat, Mr. Lee.
… I thought about our cat who is the whole day out, returning sometimes hungry sometimes not, sometimes with traces of fights, sometimes he stay also the night out.
When he finally returns, I wonder where he was and what he did during his day. This brought me to the idea to equip the cat with a camera.
And so he did. A modified VistaQuest VQ1005 Digital Keychain Camera was hooked up to a controller and put into a protective case.
Mr. Lee did the rest!
Some shots from Mr. Lee’s CatCam

Is this a deep fryer or an aquarium?
Goldfish in a deep fryer
Check the video on this website!
Okay, so the goldfish are just in there to prove a point. The guy who built this deep fryer put the fish in to demonstrate that you can have hot oil (163° Celsius) on top and cold water on the bottom of the deep fryer without the whole thing blowing up like in the video. Normally you wouldn’t want to add water to hot oil as it will make the oil jump out (don’t try it!), but this construction keeps that from happening.
The fryer has a cooling system that cools the bottom part of the oil layer enough to keep the water from boiling. This allows for pieces of batter to fall down to the bottom of the fryer, so they won’t burn up and the oil stays much cleaner.
