Henry is working on multiple audio tracks in his composition. he wants one of the tracks to start with a low volume and then gradually increase its decibel level to the normal level as it plays. which audio editing effect can henry use to achieve this?
a.
compressor
b.
normalize
c.
amplify
d.
fade in

Fade in is the audio editing technique used to gradually increase the decibel level to the normal level of sound.

Explanation:

Fade is the technology in audio editing that is used to increase or decrease the audio level gradually. It can be explained with the help of two terms: fade in and fade out.

When the audio level is increasing gradually is called fade in.

When the audio level is decreasing gradually is called Fade out.

While on the other hand compressor , normalize  and amplify are used in audio editing but they all have different purpose such as compressor used to compress the size of audio, normalize is used to balance all the level of sounds in the audio and amplify is used to enhance the sound of audio. But the only operation that is used to gradually up and down the audio is called fade.
