The mechanical design, including the speaker and microphone quality and placement, will all affect the system’s acoustic performance. Microsemi has developed MiTuner™ GUI Software (ZLS38508) and the Microsemi Audio Interface Box (AIB) hardware (ZLE38470) to automatically optimize the firmware’s tunable parameters for a given hardware design, facilitating the system design process and eliminating the need for tedious manual tuning. The MiTuner GUI Software provides step-by-step instructions that allow the software’s algorithms to achieve a high level of acoustic performance for a given enclosure. 3 © 2014 Microsemi Corporation.
