Digital aerophones and dynamic impulse response systems

Abstract

Method and apparatus for playing existing aerophone musical instruments e.g. bagpipe or constructing new instruments or more general human interaction devices by continuous estimation of the impulse response of the acoustic system of the instrument with the use of probing signal. In the proposed apparatus this is done by means of transducers introducing probing signal and capturing and analyzing the signal resulting from the interaction between the probing signal, the instrument and the player. In contrast to the normal way aerophone instruments are used where a player blows air and stimulates vibration of air this method does not require the player to blow, the generated probing signal can be outside of the audiable sound range and the output of the instrument can be outputted as digital data.
