AB  - In this study we simulated in real time the sound of a guitar amplifier loudspeaker, including its non-linear behavior. The simulation method is based on a non-linear convolution of the signal emitted by the instrument with the Volterra kernels, which were measured in anechoic conditions with a sine-sweep technique. The model has been implemented in a "VST" (Virtual Studio Technology) audio plugin. The loudspeaker simulation can be performed in real time with the Volterra kernels up to the third order and offers a good accuracy. Informal tests revealed that the simulated and the real sound were very close, although approximately 50 percent of the tested musicians were still able to hear a small difference.
