When everything's settled down, back to the main interface and click the big "Convert" button to start ripping Blu-ray to MKV with converted Dolby Digital and DTS 5.1 audio tracks. Step 4: Start to rip Blu-ray with AC3 and DTS 6 channel. Wednesday at 7:55 AM #21 abdo123 said: Atmos does not have 'bed' channels. Thread starter Samfandesreds Start date Tuesday at 7:57 AM Prev. Both of these formats have their own advantages and disadvantages when. Both these formats make use of different technologies in order to encode data and to improve the overall quality of the digital file. DTS and AC3 are both codecs which are commonly used in different sound systems to produce high quality audio. Depends on WHERE you want to play the file. About compatibility: AC3 its more compatible if you want to use different hardware for it. DTS sounds amazing on plex with supported hardware (roku for example). The press was hyping DTS as being superior and everyone thought "heck, more bits means better sound." I had played with a Dolby AC3 encoder at different bitrates in the past and I had learned some of the badness that audio compression can cause.AC3 sounds great on Apple TV. The main reason is that both of the codecs are already efficiently compressed.DTS vs AC3 DTS's 1.5 Mbps bitrate is almost four times greater than AC3's 384kbps rate. For the most popular Blu-ray HD-audio formats like DTS-HD Master Audio and Dolby TrueHD the difference is almost none and equals only 2% or 1%. For each 1,000 gigabytes of compressing DTS-HD MA / TrueHD / LPCM to FLAC you will save 20 / 10 / 100 gigs accordingly.
