Digital Guitar Body Mode Modulation with One Driving Parameter
نویسندگان
چکیده
In this study we have developed a digital guitar body mode modulation technique where the modulation can be controlled through one driving parameter. The filtering and modulation is done with frequency-warped recursive filters that have been implemented in real-time on a modern DSP processor. By changing the warping parameter the perceived size of the body can be controlled, by a pedal or automatically, resulting in an interesting effect. This effect is useful both for the electric and the amplified acoustic guitar. Perceptual properties of the effect are studied by a listening experiment.

متن کاملMore acoustic sounding timbre from guitar pickups
Amplified guitars with pickups tend to sound ’dry’ and electric, whether the instrument is acoustic or electric. Vibration or pressure sensing pickups for acoustic guitars do not capture the body vibrations with fidelity and in the electric guitar with magnetic pickups there often is no resonating body at all. Especially with an acoustic guitar there is a need to reinforce the sound by retainin...

The evolution of instruments mirrors changes in technology, culture, and society. In the early twentieth century; engineers, inventors, and tinkerers started to experiment with ways of using advances in mechanics and electronics to record, enhance, and produce sound. Concrete examples of this phenomenon can observed in devices such as: the Telharmonium, a device which transmitted sequences of t...
