 PRESS RELEASE
July 3, 2009
GritTec laboratory announced new version of active noise cancellation technology of speech enhancement.
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.
