about how to use an ordinary home computer as a means of video, 15 years ago could only dream of.Here, really, we are witnessing the predictions of science fiction writers have become a reality.Nobody will be surprised views microphone connected to the computer - this is quite specific device.For a long time the possibility of the connection has been claimed by various musical groups, amateur enthusiasts (which is protocol support ASIO), but gradually the situation changed.
Currently, every self-respecting manufacturer of notebooks in the mandatory product integrates a microphone and video camera.The reason was a significant reduction in the cost of computer equipment, which made it accessible to everyone, as well as attractive price offers from Internet service providers.The appearance of the famous Skype (Skype), supporting full video calling, and in the future, and other similar programs, to create the necessary policy framework.
Not surprisingly, many users of such applications, and in combination, the owners of cameras and microphones, so eager to learn how to increase the microphone volume.The problem of hearing the interlocutor there for a long time.Developers of programs that interact with the microphone mechanisms are constantly improving sound capture and transmission, so the problems with how to increase the volume of the microphone does not normally arise.Its increase - this is one of the simplest ways to improve audibility.
Why one microphone can hear well, and with another - a bad thing?The whole point of sensitivity.It determines how quiet the sound of the instrument will be able to grasp.The principle of operation of such devices is based on converting sound pressure into an electric current, subsequently amplified.
Obviously, "to increase the volume of the microphone" - means to increase the gain.But there is one feature.She is very familiar to owners of digital cameras with high sensitivity (ISO 1600 and above): the gain increases with an increase in the number of spurious noise.So in the case of a microphone: the excessive amplification of the signal leads to wheezing and failure frequencies.That is why when buying this device should choose the model with maximum sensitivity, and then not to seek a way to increase the microphone volume.Unfortunately, judging by the questions on the forum, it should not all owners of the PC.
in how to increase the volume of the microphone, there is nothing difficult.If the sound card driver installed correctly, in the taskbar of the operating system Windows, next to the clock, shows the speaker icon is not crossed.With the cursor on it, press the right mouse button and from the menu select "Recording Devices".From the displayed list supports recording devices need to select "Microphone", it is usually the top.Select it and click "Properties".Then follow the menu "levels".Moving the slider to the left or right can be correspondingly reduced, to increase the gain, increasing audibility of sound transmitted by a microphone.We take into account that Microsoft has deliberately established a gain of 66%.Too high a value will lead to wheezing, and lack of - to the hard of hearing.
Here you can select «+ 20dB Boost».This software enhancement, measured in decibels, to complement the above adjustment slider.It is recommended that «boost», and the volume is reduced.
Now, any user will be able to understand how to increase the microphone volume.However, despite this opportunity, with the purchase of a separate instrument to refrain from buying too cheap models.
