AEC Auto-Tuning

To optim iz e t he ac oustic properties of a given system des ign, the Audio Proc es s or f irm w are requires gain and leve l

tuning. The mechanical design, including the speaker and microphone quality and placement, will all affect the

system’s acoustic performance. Microsemi has developed MiTuner™ GUI Softw are (ZLS38508) and the Microsemi

Audio I nterface Box ( AIB) ha rdware (ZLE384 70) to automat ically op timize the firmw are’s tunabl e parameters for a

given h ardware design , facilitating the sy stem d esign p rocess and elim inating the ne ed for tedious manual tuning.

The MiTuner GUI Softwa re provide s ste p-by-step ins t ruc t ions that allo w the s oftwa re’s algo rit hm s to achieve a high

level of aco us t ic perf orm ance for a given encl os ure.
