Fabricated: Scientists develop method to synthesize the sound of clothing for animations (video)
Developments in CGI and animatronics might be getting alarmingly realistic, but the audio that goes with it often still relies on manual recordings. A pair of associate professors and a graduate student from Cornell University, however, have developed a method for synthesizing the sound of moving fabrics -- such as rustling clothes -- for use in animations, and thus, potentially film. The process, presented at SIGGRAPH, but reported to the public today, involves looking into two components of the natural sound of fabric, cloth moving on cloth, and crumpling. After creating a model for the energy and pattern of these two aspects, an approximation of the sound can be created, which acts as a kind of "road map" for the final audio. The end result is created by breaking the map down into much smaller fragments, which are then matched against a database of similar sections of real field-recorded audio. They even included binaural recordings to give a first-person perspective for headphone wearers. The process is still overseen by a human sound engineer, who selects the appropriate type of fabric and oversees the way that sounds are matched, meaning it's not quite ready for prime time. Understandable really, as this is still a proof of concept, with real-time operations and other improvements penciled in for future iterations. What does a virtual sheet being pulled over an imaginary sofa sound like? Head past the break to hear it in action, along with a presentation of the process.
Japan considers adding noise pollution to hybrids
Any big city bicyclist knows that being small and silent on the street is a deadly combination. Drivers of 2-ton cages are simply immune to anything but the sights and sounds of combustion engines riding four on the floor. This issue affects silent-running hybrids and compact electrics too, something Japan's government is taking seriously in a new government review that could result in a mandate for the inclusion of "a sound making function" in their future eco-rides. Safety aside, we presume Japanese manufacturers would choose a sound that's as tasteful and unassuming as their locally brewed hybrids. Imagine if GM was to make a similar decision... oh, right.
Today's juiciest game video: Fruit-for-blood sound effects
A video showing Foley effects for Dark Sector wins our pick of the day. There's nothing new about using abusing fruits and vegetables to make game sounds, but we still like this demonstration by the action game's sound designers. You'll never look at an orange the same way again.See -- and hear -- the clip after the break.
