A modern computer is hard to imagine without a microphone. It is part of a sound recording and volume-enhancing system. If there is no such device, a number of very important functions will disappear without a trace:
- the ability to communicate with friends through instant messengers and chats;
- recording audio information;
- the ability to create videos.
Basically, laptops are already equipped with microphones and have tuning systems. But in most cases, for personal computers, the device will have to be purchased, connected and configured accordingly.
How to check the microphone on the computer
Checking the functionality of the device as part of the design of the computer, and external, occurs according to uniform rules. The essence of the approach is to launch, try to record noise and voices on it, or test by communication.
Validation using the capabilities of the operating system
In each modern software platform, the creators have provided for the placement of effective tools for working with sound. therefore microphone settings are mandatory.
There are several ways to verify this. To do this, use the live broadcast mode, the sound recording program and the sensitivity indicator.
To implement this method of verification, you must perform a certain algorithm.
Validation algorithm
- The user should find the "Start" button, go to the "Control Panel" item.
- Next, find the subsection "Equipment and Sound".
- Inside this page there is a “Sound” window, and in it is a “Record” tab, in which information about the microphone and other sound recording devices is placed.
- You can immediately test the microphone using the option “Listen from this device”.
IMPORTANT! When conducting the test, remember that the speakers, internal or external, must be involved. Otherwise, nothing will be heard.
By the way speakers may sometimes not beor the corresponding settings have not been made. But this does not mean that you cannot test the device.
In order to achieve a positive result, you should return to the "Record" tab and use the indicators of the special scale. Its icon is located on the right side of the microphone image..
- If everything is in order, green stripes will move in the image.
- If not, their color will change to light gray.
IMPORTANT! This mode is good for checking the operability of the device. But to make settings, it will not work.

- When voices, music and noises are recorded, the device is in working condition. At the same time, you can check the quality of the recording and its playback.
Verification using instant messengers
Effective method, since such programs do not make sense to use without a working microphone.
For testing you can choose any program. It is more ancient and traditional Skype, rapidly gaining popularity Viber, demanded worldwide WhatsApp.
