Helping designers of hands-free cellular phones for automobiles deliver high-quality audio and enhanced tuning capabilities is the goal of the Texas Instruments Hands-Free Kit (HFK). A DSP-based development platform, the kit provides flexible real-time voice and audio-enhancing algorithms. It includes Acoustic Technologies' SoundClear audio software—a combination of patented algorithms for acoustic echo cancellation, noise cancellation, sound enhancement, and full-duplex control. The kit also includes Acoustic's RAPID-HFK tuning tool, which allows manufacturers to tune their designs quickly and efficiently.
The kit includes a TMS320C5407 DSP motherboard, the SoundClear and RAPID-HFK software, a 120-day trial version of TI's Code Composer Studio integrated development environment, Code Composer Studio library examples, a JTAG connector, line-out and microphone jacks, an onboard microphone, a user-programmable interface including three LEDs and three pushbuttons, and an expansion peripheral connector.
