A state-space model that emulates the behavior of the string is introduced, and we explain the theory behind band pass filter control and proportional-integral-derivative (PID) control as applied to a vibrating string. After describing the characteristics of various actuators and sensors, we motivate the choice of collocated electromagnetic actuators and a multi- axis piezoelectric bridge sensor. Integral control is shown experimentally to be capable of damping the string independently of the fundamental frequency. We consider the difference between damping the energy in only one transverse axis, versus simultaneously damping the energy in both the vertical and horizontal transverse axes. We discuss the advantages and drawbacks of various string actuators and sensors and described an experimental setup. We present waveforms of actively damped string vibrations and demonstrate that the sensors and actuators must be carefully aligned in order to obtain completely independent control of the vertical and horizontal transverse axes. Future work will involve implementing various sound effects for the electric guitar directly on a guitar string. For example, the tremolo effect consists of periodically varying the amplitude of an input signal, and so the active damping parameter could be varied periodically to achieve this effect.

This paper explores cabling options for new and emerging applications of digital audio communications. Enabling features include remotely powering devices over the audio cable and bi-directional communications. Remote power benefits both ends of the audio reproduction chain: microphones and instrument pickups on the input end and loudspeakers and headphones on the output end. Bi-directionality is an important feature because so many audio applications have inputs and outputs that are physically proximate, e.g., headset microphones with monitoring, stage boxes, and signal processing effects. In contrast to studio situations, the aforementioned \"live\" audio applications require processing elements to be physically dispersed in locations where it may be expensive or inconvenient to provide electrical power. Note that although a guitar, for example, is primarily a source of audio, the guitarist can certainly take advantage of audio sent down a single cable to provide a monitor audio feed, or a tuning reference. Providing headset monitoring is now widely accepted practice for singers in live performance application, favoring a bi-directional audio link. There are also opportunities in digital audio applications to exploit bi-directional communication of gestures and indicator values [3]. The remote power requirement precludes optical and wireless approaches, leaving twisted pair and coaxial as the main alternatives. The computer industry has recently focussed on twisted pair solutions with USB [4] and Firewire [5]. GMICS [6], an interesting new proposal from Gibson Guitar, adopts 100BaseT Catagory 5 cable as one possible physical layer implementation for a multi-channel protocol supporting powered, bi-directional communication.
