Dual Microphone Array Crack Free Registration Code [32|64bit] 🆙

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;

■ Hardware implementation of speech enhancement techniques
■ Using dual microphones can cause reverberations on
■ target audio signal
■ Forward-reverse correlation of target signal and masker
■ space is needed to be implemented.
■ Dynamic of target signal and masker is detected and
■ it’s bandwidth is reduced before correlation.
■ Here target signal is to be corrected by noise and ambient
■ noise.
■ Here bandwidth of reference signal and masker is
■ reduced before doing correlation.
■ Here reference signal is to be corrected by noise and
■ ambient noise.
■ Noise and target masker are zero-mean Gaussian white
■ noises.
■ Input of microphones array is in phasor form
■ so no additional delay is used.
Processing stages:
■ Feedforward masking;
■ Forward-reverse correlation;
■ Forward-reverse bias correction;
■ Admittance;
■ Noise suppression;
■ Dynamic range compression.

The device consists of 2 (two) independent sources of audio output: one for each microphone of the configuration.
The program has 2 input parameters that can be:

Voice Mail & Recording

VoiceMail Scheduler:

Voice Mail Management for use as a voice mailbox storage and is the new and improved version of the old VMS. This program allows you to setup e-mail messages to be sent to a voice mailbox via e-mail. It will be sent to a specific mailbox and be received a number of hours after the message was sent. Also, the program will automatically send you a follow up message as to when it was received.

Easy to operate:

The VMS can be used as a voice mailbox or as a recording. It is designed to be very user friendly. The user can choose the voice mailbox or recording on/off by pressing a single button when logged on. All the setup you do is done by pressing a single button and a number of options are available. The program also includes an option to create a customized mail-to field to be used when sending the message to the user. You can also choose to record the message for later listening and replay it to the user. When the message is recorded, the program displays the time and date to the user.My Home Based Business Advice

Single microphone used to record the source signal and
another independent microphone used to record a reference signal.
Then, based on these two audio
recordings, the two microphones are mounted. And
the difference of signals between the two
microphones are analyzed to eliminate the noise.
Operating principles of dual microphone array system:
■ On a receiver side, the receiver can be configured with a signal source and
two microphones. The microphones are controlled with the microphone
array to obtain near and far-field microphones output signal. Then, it
passes through the summering device. Finally, the summering device can
be configured with a particular method for its realization. For instance
by changing the attenuation level of the summering device, the sound
level of the noise can be changed. This results the balancing between
suppression of the external noise and preservation of the received
■ The typical equipment including a dual microphones configuration is
sealed to prevent the leakage of the speech signal.
■ The process includes but not limited to:
■ Determining the reference microphone output.
■ Blocking the signal from microphone 1.
■ Receiving the speech from microphone 2.
■ Receiving the noise from microphone 1.
■ Combining the microphone output signals in such a way as to
add the signal contributions while subtracting the noise
■ Finally, the microphone output signal is subtracted from the
reference microphone output to obtain the enhanced speech.
Processing Mode:
■ During the configuration phase, the user should have a set
down configuration file for a particular processing mode.
This phase is needed to achieve:
■ Preset the working environment of the microphone
■ Setting the level of microphone 1 output signal;
■ Setting the level of microphone 2 output signal;
■ Setting the level of reference microphone output signal;
■ Limiting the memory of microphone array;
■ Setting the number of noise reduction channels.
■ Limiting the setting of Maximum noise reduction (NR);
■ Limiting the setting of Minimum noise reduction (NR);
■ Limiting the setting of Maximum speech distortion (SFx).
In addition to that, the microphone array
arrangement needs to be configured with:
