Speech Enhancement 1.3

This software offers you the possibility of using a graphic equalizer for removing the stationary hindrances. Speech Enhancement represents a suite of applications that you may use when you want to imrpove the output of your microphone recording.
Single-microphone solution
This can be used for reduction of external hindrances and broadband color noises in speech signal. Controlled level of noises suppression in speech is up to 60 dB.
GritTecs Noise cancellation (NC) technology of single-microphone solution is used for reducing the external hindrances and background noises in speech signal. You can use this software for the selection of speech signal and for the selection of background noises.
Multi-microphone solution
Use this feature when noise from many different sources needs to be canceled. In its simplest form the technique uses two microphone solution.
Speaker is recorded synchronous with the source of hindrance (noise). The first microphone bases near by speaker, but the second one bases near by source of hindrance or noise.
Microphone Array solution
You can use this for reduction of external hindrances and ambient noises in speech source signal. In its simplest form the technique uses two array microphone configurations. By using acoustical beam-forming techniques, the microphone array can "focus" on the speakers position.
