Other sounds recorded from the cello and bass are also used to excite the resonators.
To display sub-round trip time dynamics, a spatial resolution of the photon density current along the axis of the resonator is introduced.
The method suits the simulation of one-dimensional resonators particularly well (vibrating strings, acoustic tubes, thin bars), which are found in many families of musical instruments.
It governs the resonator decay time and therefore the final edge of the pulse.
Using these rules, an individual resonator can be isolated for analysis.
Most retain casting sprues, and the suspension loops and resonators filled with metal during the casting process.
For example, if a tube resonator is used with several pitches, a series of dynamically resizable holes will be positioned appropriately along its length.
Similarly, resonators with controllable feedback work on the frequency domain of the sound, bringing its frequency content to the foreground of one's attention.
