Digital waveguides sound much better when played using real, live acoustical excitations.


Prototype based on a Fender Stratocaster


Sample sounds:

Try listening to the sounds with headphones for the best effect.

ExcitationModel OutputDescription
Various plucking and scraping sounds demonstrate the wide variety of excitations that can be measured with an accurate multi-axis pickup.
The first three plucks are measured with a 1-dimensional pickup, and the second set of three plucks consist of randomized, synthesized noise. The synthesized plucks sound more mechanical.
The first four plucks are measured with a 2-dimensional pickup, and the following three plucks consist of randomized, synthesized noise. The synthesized plucks sound more mechanical.
Bowing sounds quite realistic even though the excitation string segment is not oscillating at the same frequency as the digital waveguide model is tuned.
In chronological order, we compare the sound of plucking, picking with plastic, picking with a nickel coin, and a pick scrape with the coin.
A brief melody is played.
