Sounds of the Light Guitar:
A Work in Progress
Light Guitar Audio Unit for Mac OS X
This plugin reproduces the behavior of the light guitar, a musical instrument that uses light to make music and allows you to easily customize the sound of the instrument by adjusting various parameters. Simply plug in your instrument of choice, load the plugin into Garageband (or equivalent) and enjoy.
Adjustable Parameters
Power Type - “Real” power is the standard radiated power calculated for electromagnetic antennas and is the sound of the instrument from far away. “Complex” power includes imaginary numbers in the calculated power maintaining the phase response of the instrument. This setting more closely resembles the sound of the instrument for listeners close by.
Frequency Multiplier - Increase/Decrease the size of the guitar body, changing the frequency range of the instrument.
Resonance Type - Two different configurations were measured for the Light guitar, one that excites waves on the outer surface of the instrument and one exciting internal modes - both are included and independently selectable.
Instrument String - The strings on an acoustic instrument have a large effect on the instrument’s sound and the same effect applies to light instruments. However, a string for a light instrument is a coaxial cable. The real and imaginary impedance of the coaxial cable connected to the light guitar is user selectable.
Response Time - The impulse slider lets you change how long the light guitar alters music played through the plug-in.
Notes
The volume level may change suddenly while adjusting some parameters, so a low volume level is recommended during these times.
