Listening Broadband Physical Model for Microphones: A First Step
We will present a first step in design of a broadband physical model for microphones. Within the proposed model, classical directivity patterns (omnidirectionnal, bidirectionnal and cardioids familly) are refound as limit cases: monochromatic excitation, low frequency and far-field approximation. Monophonic pieces of music are used as sources for the model so we can listen the simulation of the associated recorded soundfield in realtime thanks to a Max/MSP application. Listening and subbands analysis show that the directivity is a function of frequential subband and source location. This model also exhibits an interesting proximity effect. Audio demonstrations will be given.
