Measuring a Six-hole Recorder Flute's Response to Breath Pressure Variations and Fitting a Model
This work addresses a specific problem for musicians and instrument designers by providing a detailed model of flute behavior, though it is incremental as it applies existing measurement techniques to a new instrument.
The researchers tackled the problem of modeling how breath pressure variations affect the pitch and octave of a six-hole recorder flute, resulting in a 6-DoF model that reveals octave hysteresis and includes released model parameters and data analysis tools.
We propose the Siamese-flute method that measures the breath pressure and the acoustic sound in parallel. We fit a 6-DoF model to describe how the breath pressure affects the octave and the microtonal pitch bend, revealing the octave hysteresis. We release both our model parameters and our data analysis tools.
