eletrical energy
you go in menu and and in the video camera icon you should spot a microphone and change off to on
Depending on the sound system and microphone there has to be a few things if there is a USB slot (Google it if you dont know what that is) on the system and your microphone has a USB drive then it will work I have heard of other ways though
computer cams will record sound also provided the computer has a microphone.
Description of a microphone
Sound recording software. You can download Audacity for free. It is easy to use for recording and editing.
With a microphone
A microphone is a device that converts sound energy into electrical energy. Sound waves cause a diaphragm in the microphone to vibrate, which in turn generates an electrical signal that represents the sound.
A microphone converts sound energy (acoustic energy) into electrical energy. The starting energy is the acoustic energy from the sound waves that enter the microphone and the finishing energy is the electrical signal output by the microphone.
A microphone is a device that converts sound energy into electrical energy. Sound waves cause a diaphragm in the microphone to move, which then generates an electrical signal that represents the sound.
A microphone is a device that converts sound energy into electrical energy.
A microphone converts sound energy into electrical energy. When sound waves hit the microphone's diaphragm, it produces an electrical signal that corresponds to the original sound wave.
In a microphone, sound waves create vibrations in a diaphragm which convert acoustic energy into mechanical energy. This mechanical energy is then transformed into electrical energy through a transducer, which produces an electrical signal that represents the sound wave.
A microphone converts sound energy into electrical signals. These signals are then transmitted to a recording device or a sound system for amplification and manipulation.
The singer is using mechanical energy to create sound waves when shouting into a microphone. The microphone then converts this sound energy into electrical energy which can be transmitted and amplified.

A microphone
In a loudspeaker, electrical energy is converted into mechanical energy to produce sound waves. In a microphone, sound waves cause a diaphragm to vibrate, converting the mechanical energy into electrical signals.
