Report and presentation concerning the acoustic characterization of a novel microphone array system carried out in the context of the "Music and Acoustic Engineering Capstone" course of the Master's Degree in Music and Acoustic Engineering at Politecnico di Milano in collaboration with the Image and Sound Processing Laboratory.
Microphone arrays are effective tools for capturing Room Impulse Responses, providing valuable insights of the acoustic characteristics of a room. Various types of arrays, including uniform linear microphone arrays (ULAs), can be exploited for this purpose. The Image and Sound Processing Lab (ISPL) has recently acquired four new ESticks V3 to its equipment, which are Dante powered ULAs developed by Eventide in collaboration with Politecnico di Milano. The first goal of this project is to enhance already existing position calibration methods, used to estimate the location of devices, to include constraint on the geometry of the ESticks. A second objective is to evaluate the acoustic performance of these new models and assess the suitability of the acquired signals for different applications, such as reverberation time estimation. The evaluation will be conducted through actual measurement sessions at the ISPL facilities in Cremona.
