For those people who pursue for high quality sound experience, you will have great preference for Blu-ray audio, which can deliver lossless audio quality thanks to its large capability. The following article will explain the mainly three Blu-ray lossless audio formats and also show you how to rip Blu-ray with lossless audio well preserved with the best lossless Blu-ray audio extractor on macOS High Sierra.
Blu-ray lossless audio formats
There are mainly three lossless audio codecs used in Blu-ray disc: PCM, Dolby TrueHD and DTS-HD MA.
PCM: PCM, short for Pulse Code Modulation, is also called LPCM, Linear PCM, or Uncompressed. It encodes the original master without any compression. Therefore, it takes up large amount of Blu-ray disc space. However, it carries three fronts, four surround and a low frequency effect channel at higher sampling rates and bit depth.
Dolby TrueHD: This format uses lossless compression so the audio information takes up less space on the disc than a PCM file, but no sound quality is lost in the compression process.
DTS-HD Master Audio: DTS-HD consists of two streams: a “core” with a high-resolution (but lossy) DTS track and a DTS-HD MA (Master Audio) track. The MA track is a lossless track capable of duplicating the studio master tape. Like Dolby TrueHD, DTS-HD takes up less space on a disc than uncompressed PCM. Compared to Dolby TrueHD, fewer Blu-ray players decode DTS-HD MA. This is because DTS-HD MA requires more processing power than Dolby TrueHD, so you are usually looking at a higher-priced player. Two players that decode DTS-HD MA are the Panasonic DMP-BD55 and Sony BDP-S550.
Tips: For people who don’t plan on upgrading your sound system to experience lossless audio, most Blu-ray movies have a standard Dolby Digital track, just like DVDs. It is a higher quality recording than you find on DVDs, so it will definitely sound better than you are used to but it won’t duplicate the quality of the lossless tracks. The DTS core found on DTS-HD discs is very high quality, too.
