The proposed platform allows acoustic measurements via a flexible, portable system, based on commercially available hardware, such as a personal digital assistant (PDA) equipped with a wireless adapter and a digital audio capture card as well as a personal computer (PC) interconnected with off-the-shelf wireless networking hardware. Using this hardware, three software applications were implemented: (i) a device driver that handles the communication of the digital audio capture card with the PDA, (ii) a PDA application that realizes the WiFi connection with the personal computer, also incorporating a recording function that captures data and presents the user with their analysis, and (iii) the personal computer application that initiates the playback sequence as dictated by the connected PDA. The system can assist the fast measurement of large spaces. Room Impulse Response (RIR) measurement tests were conducted in a laboratory room, in order to evaluate the effectiveness and functionality of the measurement system.
