GritTec's Noise cancellation (NC) technology is intended for reducing the external hindrances and background noises in speech signal. In new version of GritTec's Noise Cancellation (Version 2.00) developers of GritTec managed to get rid of internal distortions and musical noise arising in a consequence of using adaptive filtration technologies. This problem was especially actual in signals with sampling rate 16 kHz and above.
Testing of the new version of active noise cancellation has shown very good results of speech enhancement in comparison with the previous version and with the noise cancellation technologies of other companies.

The updated new version of noise cancellaion can be effectively applied for:
- suppression of street noises;
- suppression of office noises (fan noise, computer noise, background speech and so on);
- suppression of a various sort of mechanical noises, such as noises of avto-moto technics;
- suppression of industrial noises;
- suppression of channel distortions and noises arising in a consequence of coding and transfer of a speech signal on analogue and digital communication channels (VoIP);
- suppression of other broadband noises.

To test new version of GritTec's Noise Cancellation (Version 2.0) download the demonstration program from section of Downloads or directly via url of product page.
The package of SDK libraries including porting code for some DSP platforms of new NC version will be available for developers in the near future.
