Microphone array solution (MAS) of speech enhancement can be used for reduction of external hindrances and ambient noises in speech source signal.
The technique uses dual microphones array configurations in its simplest form. By using acoustical beam-forming techniques, the microphone array can “focus” on the speaker’s position.
By knowing the speaker’s position, output from individual microphone can be combined in such a way as to add the separate signal contributions while canceling the noise contributions.
Microphone array solution can be effectively used:
■ Wireless telephony systems;
■ Mobile communications systems;
■ Voice over IP (VoIP) telephony;
■ And other voice communications systems.
Here are some key features of “Dual Microphone Array”:
■ Support 2 microphones configurations;
■ Directional microphones: unidirectional configuration;
■ Distance between microphones not less 4 cm;
■ Far-field pickup up to 2 meters;
■ Noise suppression of stationary noise up to 15 db and up to
■ 18 db for non-stationary noise;
■ High quality of speech enhancement;
■ Low level of speech distortion;
■ Fast adaptation to changing of external noises;
■ Easy integration with target applications.

Dual Microphone Array Crack + Torrent (Activation Code) Free Download For Windows [2022]

This is a stand-alone application of speech enhancement software which provides highest level of noise suppression with minimal amount of speech distortion.
The software consists of three main components:
■ Microphone array configuration;
■ Acoustic beam-forming;
■ Output weight generation.
All three components are tightly integrated to work as a whole.
In the following section, we will show how to configure the microphone array and perform the acoustic beam-forming.
For illustration purpose, the software can be installed in a standard desktop PC
In order to select one configuration of the microphone array, click on microphone array button from the GUI
> > > > [ Screenshot of the microphone array configuration ] 1. Choose the type of microphones
Select a configuration of either unidirectional or bidirectional microphone array from the drop-down list.
2. Choose the type of the configured microphone array
Select either unidirectional or bidirectional microphones array from the drop-down list.
Unidirectional: Array of microphones are directional in a certain direction but omnidirectional when it is combined with another array.
Bidirectional: This microphone array has 2 microphones, arranged in a straight line (unidirectional microphone array).
The software supports different configuration of microphone array including:
■ Unidirectional microphone array;
■ Bidirectional microphone array;
■ Long (L) and short (S) orientation microphone arrays (4 microphones in a straight line).
■ X (in 2 microphone array and a 4 microphone array) and Y (in 4 microphone array) orientation microphone arrays.

Dual Microphone Array Crack + [32|64bit]

Dual Microphone Array Crack For Windows is a software solution. It is implemented using
“Speaker Diagonal Arrival Estimation” (SDAD) technique,
“Acoustic Beam-forming” (ABF) and “Speech Coding” (SC)
The approach uses an optimal mixture of delay, phase and gain or
attenuation, according to the noise and signal coming from the left and
right sides. The main task is to perform mixing of audio samples from
left and right microphone signals and to perform rescaling of right
microphone signal for proper audio output to the headset.

What’s New In Dual Microphone Array?

■ Dual Microphone Array consists of two microphones configured in
■ Unidirectional configuration. With this configuration, the array will
■ Work best at a distance between microphones of about 3 meters. In
■ medium-size rooms, the array will work better when the distance
■ between the microphones is about 2 meters.
■ In addition, it will work better with a single-tongued male
■ speaker.
■ By choosing the correct gain parameters, the user can enhance
■ the performance of dual microphones in different noise conditions
■ but, we have to mention that the microphone array performance
■ does not guarantee the performance of the underlying system.
■ This invention is intended for end users of telephone
■ applications, it does not solve the local circuit problems like
■ microphone array output signal-to-noise ratio (S/N ratio),
■ electrical microphone response impedance, etc.
■ Systems based on conventional technology are used to obtain a
■ dual-microphone array solution for phone applications.
■ This is mainly due to the constraints imposed by the conventional
■ implementation methods to use very near microphones, it is very
■ difficult to select adequate microphones.
■ Having solved the problems of acoustic in situ processing, this
■ invention intends to solve the problems due to the microphone
■ arrays, which are used in current systems:
■ There is no sound source coding;
■ There is no auto-adjustment of microphone response, resulting in
■ poor output signals.
■ The quality of the speech signals is usually poor.
■ The effects of the transmission network can easily be
■ introduced.
■ Speech and noise are amplified differently.
■ The signals after the network are not always similar to the
■ signals before the network.
■ Using multiple microphones, the problem of the amount and type
■ of microphone information is reduced.
■ Single microphones cannot represent a wide range of noise
■ types.
■ The binaural noise measurement becomes inaccurate.
■ The difficulties of “field-hardening” increase.
■ The delay problem for communication
