There’s a lot of things the PS3 can do...and as we move into the next generation, there’s a lot of competition with what format looks better, which console can pump out the best visuals, and so on. While the jump from DVD to Blu-Ray or HD-DVD is pretty huge for those with capable HDTVs, the jump to next-gen audio has been rather quiet.
While the debate over which format can deliver the best visuals continues, there’s one thing that’s clear: Blu-Ray has an advantage in the audio department, delivering uncompressed PCM audio that’s unlike anything I’ve heard. Today I’ll show you how to get the next-gen codecs in your living room, what you’ll need, and what to watch out for.
What is Next Gen Audio?
With the new HD formats of HD-DVD and Blu-Ray come some audio formats that are new to home theater. Here’s the breakdown of previous and future codecs:
Dolby Digital 5.1 & DTS: These are the standard codecs found on almost all DVDs. DD5.1 is common among new DVDs and games alike, and is the most widespread. DTS tracks are found on quite a few DVDs, and even a few games (GTA: Vice City for the PS2). All you need is an optical or coaxial cable to enjoy these formats, and most HD-DVDs and BD movies include a standard DD5.1 track.
DTS-HD Master Audio: This is the new DTS codec for the next gen formats. Every single Fox Blu-Ray release has a DTS-MA track...in fact, nearly all of them only have the DTS option. Now here’s the interesting thing: there is not a single product on the market today that supports DTS-MA. Even the PS3 can’t decode this codec at the moment, but the March firmware is confirmed to update the PS3 to DTS-MA specifications. Even with that in mind, you still need a reciever to decode DTS-MA, and there’s not one available right now. Heck, there’s no Blu-Ray or HD-DVD player on the market today that supports DTS-MA!
Here’s the good news: DTS-MA is simply converted to an improved DTS format read by virtually any player and receiver if the MA format isn’t supported. You’ll still hear the benefits of the DTS-MA track, but even moreso once the hardware is in place. Kudos to Fox for supporting a future proof codec that isn’t even supported on the market yet! (although all things considering, I’d still enjoy a PCM track more).
Dolby TrueHD: The standard codec found on all HD-DVDs but only a handful of Blu-Ray discs (well, just one BD title actually- Legends of Jazz). While this track is still compressed, it delivers a more robust audio experience that is a big step up from DD5.1. The HD-DVD drive for the 360 cannot support this codec due to lack of HDMI, but instead converts the format into DD5.1 that is still a step up, but not “TrueHD.” The PS3 does not support DTHD right now (it will be added via the March firmware) but instead converts the DTHD track into PCM 5.1 audio (only via HDMI). Basically both the 360 and PS3 support this codec, but not in a “true” sense for either console. Still sounds great regardless.
Uncompressed PCM 5.1: Found on a large number of Blu-Ray discs but not supported on HD-DVD, uncompressed PCM 5.1 is simply that: an uncompressed version of the film’s standard 5.1 to 7.1 soundtrack. While that doesn’t sound too exciting, believe me when I say PCM 5.1 is a joy to hear. I’ll post my own experiences in a second, but here’s what many reviewers of BD and HD-DVD discs have to say about PCM audio:
”Buena Vista continues to aggressively support uncompressed PCM soundtracks on its Blu-ray releases, and I say cheers to that. With so much talk about new audio formats such as Dolby TrueHD and DTS-HD (which are indeed great, make no mistake), it is easy to forgot that plain ol' PCM can produce some the best sound around.”
”If you haven't heard uncompressed PCM you really don't know what you're missing. I haven't heard anything from DD, DD+, True HD or even DTSHD quite on the same level. Of course the later can currently only be based on hearing the core DTS on DTS MA tracks from Fox. And I'm not convinced that the TrueHD tracks that I've heard were the best the codec can do. Regardless, PCM has delivered the most transparent audio presentations I've ever heard even at 16bit. It's like listening directly to the master tapes. Or so I imagine.”
” Buena Vista rolls out the red carpet with an uncompressed PCM 5.1 surround track at 48kHz/16-bit. What impressed me most were the quietest moments...'Flightplan' definitely delivers some of the best atmosphere I've heard yet on a Blu-ray release.”
” I have little doubt that the uncompressed PCM 5.1 surround track on this disc easily stands shoulder-to-shoulder with the best soundtracks I've heard on either next-gen format.”
”PCM again lives up to the hype, preserving a broad, open transparency with newfound detail and clarity that DVD just can't touch.“
While DD5.1 tracks for DVDs have been compressed to fit, PCM audio allows them to breathe. It’s like listening to an MP3 you downloaded off Limewire & then listening to the same track on the original CD. Another comparison would be listening to a movie with earmuffs on, and PCM audio taking those muffs off, allowing you to hear subtle details like the rain pitter-pattering on the windshield, the hum of an elevator as it moves upwards...if you think I’m exaggerating, believe me, I’m not. It’s incredible how much
