A real-time DSP implementation of a flute model
Vesa Välimäki, Matti Karjalainen, Zoltán Jánosy, Unto Kalervo Laine · 1992
A computationally efficient semiphysical time-domain model of the flute is presented. The traditional method of modeling the one-dimensional wave propagation as a transmission-line, where all the losses as well as reflection and dispersion effects have been lumped to linear filters at the ends of the line, is used. The model is excited by white noise, and the nonlinear interaction between the excitation and the tube resonator has been modeled by a static memoryless nonlinearity. The model is simple enough to be computationally efficient, but has retained many important features of a real instrument. The real-time implementation has been done on a Texas Instruments TMS320C30 floating-point signal processor using a sampling rate of 44.1 kHz.>
