Most Blu-ray ripping tools only keep 1~2 audio tracks when ripping a Blu-ray, so you’ll lose original AC3 or DTS 5.1 surround sound. That’s really annoyed. The lucky thing is that you have come the right place, this simple guide will provide you an easy to rip Blu-ray with AC3 and DTS 5.1 surround sound as you like. Read on to find out more.

What’s 5.1 surround sound, AC3 (Dolby Digital) and DTS?

5.1 Surround Sound

5.1 surround sound is the most common format. It includes a total of six channels — five full-bandwidth channels with 3-20,000 Hz frequency range for front left and right, center, and left and right surrounds, plus one “low frequency effects” (LFE) subwoofer channel for frequencies from 3-120 Hz.


AC3 standing for Audio Coding 3, is a file extension for surround sound audio files. It is created by Dolby Laboratories in 1987 for use on DVDs, Blu-ray players, HDTV programming and home entertainment systems. AC3 format contains up to 6 discrete sound channels. The most frequently used 5 channels are dedicated for normal-range speakers (20 to 20,000Hz) and 1 channel for low frequency (20 to 120Hz) subwoofer effect. Specifically, they are left front, right front, center, left rear, right rear and 1 ultra-low track called 5.1 channel which is the standard surround sound audio most commonly used in commercial cinemas and home theaters.


DTS stands for Digital Theater Systems (now officially shortened to just DTS). Like Dolby Digital, DTS provides 5.1 channels of digital audio. However, DTS uses less compression than Dolby Digital. As a result, some say that the sound produced by DTS is slightly more accurate than the sound produced by Dolby Digital. While most audio/video receivers will have both Dolby Digital and DTS, fewer discs and video games are encoded with DTS, compared to the number encoded with Dolby Digital.
