For developers and manufacturers that require a complete hardware/software solution for integration into their systems, or for development engineers looking for a "quick start" solution to noise and echo reduction technology, we provide three ready to use hardware/software modules.

These modules have been proven in products ranging from corporate business intercom systems to specialist intelligent speaker systems for radio communication. If you are looking for a complete solution, get in touch !

The ClearSpeech Mic Board:

The ClearSpeech Mic board is a fixed-point single channel platform based on the ADSP2184 DSP and AD73311 codec. The board is designed to run one variant of our noise reduction algorithm only. Standard code provided on this platform is 16kHz sampling rate, 12dB white noise reduction ASF. The platform provides mic or line level input, adjustable output gain, noise reduction on/off switch, 3.5mm jack input and 2.5mm jack output connectors.

The ClearSpeech Module :

The ClearSpeech Module is a fixed point dual channel platform providing a
digital signal processing core for running NCT's ClearSpeech noise
reduction, echo cancellation and signal conditioning algorithms. Three
standard EPROMs are available; AECASFII, RNFASF and BPFASF. Consisting of
DSP, EPROM, CODEC and watchdog timer, this platform is a convenient starting
point for customers wishing to integrate NCT's technology into their own
embedded applications. Supplied with in-line connectors and mounting holes,
the Module can be readily attached to the customer's platform.
