Before I will explain about Dolby digital, Dolby digital 5.1, Dolby Digital Surround Sound I would like to introduce with terms like “Mono” & “Stereo”.
In old times, before Dolby, “Mono” & “Stereo” was famous.
Mono is a single channel or single speakers. Recording and listening both was in Mono or single channel.
In “Stereo”, there was left and right channels or speakers for recording and listening both.
Now, I am introducing Dolby Digital Or Dolby Digital 5.1. Dolby digital previously called AC-3.
Dolby digital or Dolby 5.1 means we can record with 5.1 and also listen in 5.1 channel.
After Dolby digital was introduced in the market, the sound quality was better than before.
Stereo And Dolby Digital Channels:
2 Channels (Left & Right).
In stereo, you can feel the sound only from left and right.
Dolby Digital’s Channels:
5.1 channels (left, right, center, rear left, rear right) & 1 subwoofer.
In this Dolby digital surround sound, you will listen sound from everywhere from left, right, rear left, rear right, center.
Lest explore the Dolby digital 5.1 a bit more:
Dolby Digital technology supports 2.1, 3.1, 4.1 & 5.1 channel.
In 5.1, the front three channels (left, right, center) gives you the clear diagoules and other two (rear left, rear right) is for creating the surround sound of being in the middle of the action. That’s all about the main 5 channels.
Talking about the .1. .1 is for subwoofer. Subwoofer is for low frequency and low bass.
Stereo And Dolby Digital Or Dolby digital 5.1 Sound Quality
In stereo, if you are listening the voice of moving helicopter in stereo channel, you will experience the voice goes from left to right. When the helicopter moves from left to right, you left ear listens it first and slowly feels the low voice in your left ear. And your right ear experience the high voice as the helicopter moves to your right ear.
Dolby Digital’s Sound:
If you listen same hellicopter’s voice in Dolby digital 5.1 channel, you will experience a very accurate voice. You will feel that you are sitting really in that environment where hellicopter moves around you. Surround sound add realism wheather you are watching movies, listening to music or anything.
