For a good long while now, IK Multimedia has been helping to satisfy the mobile noodling needs of electric git-fiddlers with a succession of instrument interfaces that bridge the gap between a smart device hosting digital effects and amp simulations and a plank of wood, some pickups and a few strands of tensioned steel. Now the company is taking aim at dreadnought picker types with the iRig Acoustic, which is billed as the first acoustic guitar mobile microphone/interface specifically made for acoustic guitars and ukuleles, and one that's claimed to rival pro-grade studio microphones.
Researchers from the University of Leeds and Sheffield University have
created a way to move data through magnetic nanowires by using surface
acoustic waves as the motivating force. Being developed for use in
so-called racetrack solid-state memory,
the researchers claim that using sound waves for data transfer should
markedly increase computer processing speeds while vastly reducing power
Last year, researchers at the University of Dundee revealed an acoustic tractor beam that used ultrasonic energy to pull macroscopic objects in. Now researchers in the UK have developed a sonic tractor beam that generates acoustic holograms through the manipulation of high-amplitude sound waves. These acoustic holograms, which can take various shapes, such as fingers, cages and vortexes, are able to pick up and move small objects like polystyrene beads.
Players wanting to change the sound or timbre of an acoustic guitar, or just clear up any nasty tone issues or feedback, can look to digital processing or post-production for help. But Keeler Sound's Performer Series sound processors for nylon and steel string instruments make use of pipes and ports for the promise of an as-the-music-happens "perfectly balanced tone." Swapping out a unit's diaphragm, or not using one at all, will also alter the tone of the guitar.
