ZZ2 Project

Subject: Acquisition and processing of sound signals to control various equipment
Tool: LabVIEW 17
Duration: 30h/person
Year: 2022/2023
Members of the group: Jamila KAMAL & Thomas QUENTEL
External manager: Jean-Thierry Bodin
Project author: Lauriane CHARIÈRE--FIEDLER
Academic Manager: Mamadou KANTÉ

Our project consists in developing a program that would acquire sounds through various microphones and realise signal processing. The final product should inform the user of the power averages of the Power Spectral Density (PSD) in given ranges of audible frequencies that is between 20 Hz and 20 kHz. It has to be functional on Windows 10 and 11 and for all types of microphone.
Currently, and with that marking the end of our project, our program functions for only one microphone connected. The development was carried out and tested under LabVIEW 17 working on Windows 10/11 as Operating System.
This programme is intended to enable a student from the Beaux-Arts to make electrolytic engravings on copper from the sound acquired in an environment.
