what is gain on a microphone

Gain on a microphone refers to the amplifiers ability to increase the signal strength from the microphone. It is essentially the amount of amplification applied to an audio signal. By adjusting the gain knob on a microphone, you can control how loud or soft your recorded audio will be. Gain is measured in decibels (dB) and can be controlled by a knob on your mixing console, interface, preamp, or sometimes even the microphone itself. The amount of gain required for a microphone will depend on the closeness and volume of the sound source the mic is capturing. Essentially, the main objective is to amplify the signal to a secure line level and make it equal in signal strength to the other equipment around the area. Gain plays a crucial role in adjusting the sensitivity of your microphone and can help you control sounds and their intensity and depth, essentially shaping the character of your audio output.
