 Hello everybody, my name is Mauro Scanduzzo, I'm a field application for ST Microelectronic and today I'm going to present a solution, audio solution for application related to audio called Smart Mic One. The hardware that we need is this one. So we are starting with a nuclear board and on top of that we apply a microphone expansion board with an implementation with four microphone arrays. On top of that we have a terminal board to enable the audio to be connected with loudspeakers. All the systems can be connected to a portable device, let's say a laptop or a PC, through a USB connection. The hardware solution comes also with a software solution and a software package. The software package has some library implemented to address audio application. The library that we have is one is for source localization to understand the angle of arrival of the sound, another is the bin forming to select a portion of the audio if you want to select one particular speaker on the conversation and another one is the acoustic echo cancellation. That are the three libraries that ST offer in the package. On top of that we need a GUI interface to communicate with the PC, with our PC. So the communication is through virtual common port. This is the GUI interface and you can enable different kind of feature. Let's start with the first one. So the bin forming, so the bin forming you can select the different direction, you have eight different directions with a 45 degree of portion of air that you can select. On top of that you can apply different kind of algorithms from a cardioic basic to a strong cardioic. The different is in term of MIPS require and also performance for the bin forming. The other feature enabled with the GUI interface with the graphical user interface is the source localization. The source localization has the possibility also to set a threshold and also a resolution. The other part is the acoustic echo cancellation. The acoustic echo cancellation is enabled with this part in order to remove let's say a song to the speech if you have like application like a smart speaker. That is in short presentation then I prepare for you today. Thanks for your attention.
