To inquire about whether a home theater is 5.1 or 7.1, what is Dolby Panorama, what he is, and how he came from, this note tells you the answer.
1. Dolby Sound Effect is a professional audio processing technology and decoding system that allows you to enjoy music, watch movies, or play games with a more realistic, clear, and stunning sound experience. Through special sound effects processing, Dolby sound effects can increase the depth, breadth, and spatial feel of audio, making people feel as if they are in the scene, feeling every subtle note and sound effect.

2. Usually, we watch TV and listen to music in stereo with only two channels, while 5.1 and 7.1 usually refer to Dolby surround sound, which is a sound system composed of multiple channels.

3. Five plus one equals six indicates that 5.1 has six speakers, and seven plus one equals eight indicates that the system consists of eight speakers. Why not just talk about the six channel system and say the 5.1 system? It is necessary to understand that the one after the Decimal separator represents a subwoofer, that is, a subwoofer. If the number is changed to two, there are  two subwoofers, and so on.

4. The five and seven in front of the Decimal separator represent the main speakers. The five speakers are the left and right main boxes in the middle and the left and right surround respectively. The 7.1 system adds a pair of rear surround on this basis.

Not only that, Dolby sound effects can also automatically adjust the decoding method based on the audio playback device you use, ensuring that each device can achieve the best sound effect. Especially when using Dolby sound effects in home audio and video systems, it can bring you a more immersive viewing experience.
