Measuring a Six-hole Recorder Flute's Response to Breath Pressure Variations and Fitting a Model

TL;DR

This paper introduces the Siamese-flute method for measuring breath pressure and sound simultaneously, fitting a 6-DoF model to analyze how pressure influences pitch and hysteresis in a six-hole recorder flute.

Contribution

It presents a novel measurement technique and a 6-DoF model to understand breath pressure effects on flute pitch, including hysteresis phenomena.

Findings

The model captures the relationship between breath pressure and pitch variations.

Hysteresis effects are identified in the octave response.

Data analysis tools are provided for further research.

Abstract

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.
