In a professional task, before we can begin to publish our audio project we need to make the sound composition in a proportional level and also meet to the standard level, so when a people play it, the sound will be heard in comfortable for ear.
The basic function such normalizing volume and amplify is very useful and we often use it to gain or turn down the volume level for any part or even entire of project. Audacity come with this function as a default so we can use it even we don't have any plug-in
