Speech Enhancement 1.43

GritTecs Noise cancellation is used for reducing the external noises in speech.


GritTecs Noise cancellation (NC) technology of single-microphone solution is used for reducing the external hindrances and background noises in speech signal. NC can be used as for the selection of speech signal, so and for the selection of background noises. NC is recommended to use in case of an amount of hindrances is unknown beforehand or it is impossible in the evident type to select "point" source of hindrances (absent-minded hindrance). Filter noise cancellation is automatically adapted under all types of surrounding hindrances and selects a refined of speech signal.

FEATURES:
- Single microphone solution;
- High quality of speech enhancement;

- Separation as cleaned speech signal, so and background noise;
- Three modes adaptation to background noises;
- Controlled level of noise suppression in speech, including broadband color noises up to 60 dB;
- Possibility of using a graphic equalizer for removing the stationary hindrances;
- Easy integration with target applications.
