Living beings with a sense of hearing have an inborn ability to separate the sounds they collect from their surroundings and they only process the ones they consider important at that point. Since species other than humans yet have no interest in utilizing digital audio content, we shall focus on our species and try to explain how things work. Namely, if we did not have the ability to filter all of the sounds and vibrations coming from the external stimuli, we would end up dazed and confused since our brain would be overloaded with abundant information.

It is not that our brain fails to gather the info, but it rather selects what is important and processes the information of value. The other sounds that we do not notice are still there and are collected by our consciousness, but are not considered to bring any useful data at the time speaking.

Think of a song as a collection of various sounds coming from different instruments. We almost always listen to a song as a whole, not as a combination of different sounds, yet, if we focus on a certain instrument, we might be able to hear it separately from the whole. Sure, humans have no ability to mute all the other sounds only to focus on one sound of a song, but we can focus on it in order to observe it more closely.

What digital audio watermarking does is the implementation of certain sounds in digital audio composition, but in a way that your ear cannot notice it even if you try really hard. Therefore, this particular approach to the protection of intellectual property allows end-users to enjoy their content without any obstructions, while the authors of various compositions get their credit.

Therefore, low frequencies are used to put a watermark into an audio file. When we talk about the detection of a watermark, it is designed in a way that after the activation of the file, both the user and the artist are secured from copyright issues.
