Pluck Lab
A keyboard guitar synthesized live by Karplus-Strong, with the filter on screen.
What it does
Hear how a computer turns random noise into a plucked-string sound, live in your browser. Play chords and single strings from the keyboard while the screen shows the vibrating string, its harmonics and the output, slowed down as far as you like without slowing the sound. Seven guided lecture scenes cover pitch, why high notes fade faster, tone, pick position and strum timing, and students can write their own filter and get an instant analysis of what it does to the sound.
Good to know
It uses the textbook model, so it sounds like a plucked string rather than a recorded guitar.
