Advisor: Huseyin Hacihabiboglu, Ph.D., SMIEEE.


Topic: Guitar modeling and simulation using Extended Karplus-Strong algorithm.

  1. Understanding the theory of Karplus-strong algorithm in physical modeling sense, physical waveguides.
  2. Move onto Extended Karplus-Strong algorithm theory, understanding the extended effects.
  3. Transforming this approach in digital domain, and implementing into a program (using JUCE or STK library)
  4. Parameter estimation using recorded audio of playing a string of a guitar.
  5. Playing music scores using the synthesised voice of a real guitar
