Consumers today demand electronic products that are small and portable, without giving up any performance. Imagine a conference speakerphone that provides clear and crisp full-duplex communication, all in the size of a credit card someone can carry in their pockets. This same speakerphone can be used on the road, at work, or at home as a hands-free car kit, a conference speakerphone, or as a VoIP phone for internet chatting. Fortemedia’s echo-canceller solutions make these applications a reality. Fortemedia voice processors enable designers to develop innovative applications with previously unattainable performance and small form factors.

Included below is one example of how products with SAM technology can power a universal portable speakerphone. A one piece solution with both microphone and speakerphone in the same housing, this product provides clear and noise-free communication while supporting peak loud speaker volumes of 120dB. By taking advantage of Fortemedia’s beam-forming small array microphone technology, this unit can suppress non-stationary noise of up to 25dB. This product connects to a cellular phone through Bluetooth, and as shown in the usage models below, can be used as a hands-free car kit, a conference speakerphone, or a personal speakerphone for hands-free communications.
