What is 7.1 surround sound and how does it work?
7.1 surround sound is an audio technology that uses eight channels to create a more immersive listening experience. It consists of seven full-range channels: left and right front, center, left and right rear, and left and right side surrounds, plus one subwoofer channel. This setup is designed to envelop the listener in a 360-degree sphere of sound, making them feel like they’re part of the action.
The way it works is that each channel is responsible for producing a specific range of frequencies, which are then directed towards the listener from different angles. The left and right front channels handle the main audio, while the center channel provides a clear and focused sound for dialogue. The rear and side surround channels add depth and ambiance, and the subwoofer channel provides the low-frequency effects that rumble and vibrate.
What is Dolby Atmos and how does it differ from 7.1 surround sound?
Dolby Atmos is a more advanced audio technology that allows for a much greater number of audio objects to be precisely placed and moved within a three-dimensional space. It can handle up to 128 simultaneous audio objects, each with its own specific location and movement. This creates a much more immersive and realistic audio experience, with sound effects and music that seem to come from all directions, including overhead.
The main difference between Dolby Atmos and 7.1 surround sound is that Dolby Atmos uses object-based audio, where each sound is treated as an individual object that can be precisely placed and moved. This allows for a more precise and realistic audio experience, especially in scenes with complex action sequences or realistic environments. In contrast, 7.1 surround sound is more focused on creating an immersive experience through channel-based audio, where the sound is directed towards the listener through a fixed number of channels.
Which is more immersive, 7.1 surround sound or Dolby Atmos?
