Understanding Stereo Sound
Standing for Stereophonic Sound, stereo sound refers to an audio system that produces sound through two speakers. Someone may ask, where are the two speakers? I will tell you that you can find them on both sides of a TV, a music system, or a stage. Specifically, one is on the left side while another is on the right.
In addition, stereo sound plays an important role in recording high-quality music of all kinds. More than that, it is very easy to use, which brings you less difficulty in the installation process. Plus, when your budget is limited, stereo sound can be preferable for you. However, it has little to offer in sustaining an immersive movie experience.
Understanding 5.1 Surround Sound
As a part of multi-channel sound, 5.1 surround sound can be defined as an audio system that utilizes five speakers and a subwoofer to produce sound. Simply put, it comprises six audio channels and provides people with a nice auditory experience.
With 5.1 surround sound, you are capable of enjoying a better movie-watching experience in your home theater. In addition, 5.1 surround sound can be a better choice to watch science fiction or action movies. If you are a console or PC game player, it can help you gain the game sound with more depth. However, if you want to use 5.1 surround sound, ensure that your budget isn’t tight.
