Noise and Echo Cancellers
Frequency Domain Echo & Noise Canceller Print E-mail

Echo and Noice CancellerOur new acoustic echo and noise canceller (AEC) is based on an all-new concept whereby not only echoes but also background noise are suppressed.

It is perfectly suitable for hands-free applications in noisy environments such as car interiors or industrial locations.

Currently, the algorithms is available for Blackfin platforms with implementations for other platforms under development.


Please, have a look at the datasheet or call us to discuss your particular application.
 
Line Echo Canceller Print E-mail

Our implementation of a G.165 Line Echo Canceller (LEC) is designed to reduce or even cancel electrical echoes in the transmission of speech signals. The tail length of the echo suppression can be adjusted to system requirements. The algorithm is required in DECT telephony systems and similar applications.

Acoustic Echo Canceller (G.167) Print E-mail

Our implementation of a G.167 compliant Acoustic Echo Canceller is designed to cancel acoustic feedback between a loudspeaker and a microphone in loudspeaking audio systems. The tail length of the echo suppression can be adjusted to system requirements. The algorithm is required in speaker phones, teleconferencing devices, voice-control systems or alike. This AEC requires very few MIPS making it suitable even for micro-controller platforms.
