    I posted this on IMDb years ago on the Blu-ray Hugh Def Equipment board. I no longer have to worry about this issue, but it's a nice walk down Memory Lane.

    I posted this on IMDb back in 2011. Six years later, my folks are still too cheap to solve this problem. However in recent years, I've learned how to watch everything with headphones. Said headphones kick the ass of any speaker in my house, save my hi fi stereo.

    It's actually been proven that humans can hear hi-rez audio.

    I asked this question way back before I knew much about 24p technology or lossless audio.

    Here it is straight from the IMDb archives.

    Just a clarification: You can get the HD audio if you set your player to output PCM. It's better than nothing.

    This was originally posted nearly seven years ago.

    Here's what the Speaker Wizard said:

    Lots of good technical info that would be a tragedy to lose.

    Not only is there some good information here, but also a history lesson.

    EQ is equalization. It refers to cutting or boosting bass, mids, or treble. For playback purposes, it's usually best to set everything flat (or, at the middle/12:00 position); that way, nothing is being cut or boosted, and it sounds the most natural.

    Most systems nowadays (2017) should be able to support DTS, especially Blu-ray players, which support DTS-X and earlier (lossless DTS-HD Master Audio, DTS-HD High Resolution, and regular lossy DTS).

    I'm actually a big fan of DTS (especially theatrical and DTS Master Audio). Dolby is nice, too, but I usually have to turn up Dolby TrueHD louder than I do DTS-MA. TrueHD is typically mixed lower than Master Audio.

    In 2010, Toy Story 3 became the first theatrical release to utilize discrete 7.1 surround sound. How does it compare to 5.1? Let's find out.

    [post deleted by admin.]

    5.1 uses the standard six channels and can go up to 192kHz. 7.1 uses two extra rear channels (thus, eight channels), and maxes out at 96kHz.That's the only real difference between the two. One is not necessarily better than the other; Christopher Nolan uses 5.1 to this day.

    Woody Allen cuts his films in mono to this day. Just sayin' :cool:

    I think it's much more significant how much effort and creativity is put into the sound design and mix, than what format is used. These days, all films have very complex and professional mixes, but if the director doesn't really get into sound design (and all great directors are into sound -- topic for another thread) then it's just a mish-mash of recycled garbage from other film mixes. I guess it's not redundant to say that Apocalypse Now was the granddaddy of 5.1 films, and few releases since really deserve or need to be put through a proper 5.1 system.

    Was the Betamax player and tapes really better than the VHS player and tapes?

    Or was this just a myth?

    And if it is true, why was this so?

    Never had a Beta, but I blew thru my share of V H S recorders. My friend had a Beta, but it was in the shop more than it was out.◆◆◆♡♡♡

    Some say Video 2000 was the best system.

    Why don't perpetual motion machines ever work?

    Being an audiophile, I recently compared lossy DTS to Dolby Digital (and PCM)… just out of curiosity.

    I used all three audio tracks from Led Zeppelin DVD (apples to apples and all). I sampled "We're Gonna Groove," "I Can't Quit You Baby," and "Dazed & Confused." Here's which audio came out on top:

    PCM - The top of the food chain. Uncompressed. It sounded (and felt) so live.
    DTS - The second-best. Jimmy Page's guitar and John Bonham's drums still pack one hell of a punch. John Paul Jones's bass is still discernable from Jimmy's guitar. Robert Plant's voice is still dynamic. You can still tell each instrument apart and everything still has life.
    Dolby Digital - Not bad, but it doesn't quite cut it. A tad muddy compared to DTS and especially PCM. Jimmy's guitar is somewhat lacking. Instrument separation is still good. The sound is average, at best.

    I didn't find any of the tracks to be brickwalled or dynamically compressed.

    Comparing DTS to Dolby Digital might seem a bit outdated in the age of Dolby TrueHD (and Atmos) and DTS-HD Master Audio (And DTS:X, etc.), but I was curious as to why Spielberg has always preferred DTS.

    More audiophile fun!

    Have you ever wondered how far to adjust volume controls on your computer and your speakers/headphones? I've been wondering for a while, and I always thought my headphones performed better than my speakers. They're cheap Dell speakers (vs. premium Sony headphones) that came with my old Vista PC, which I still use for my Windows 10 PC, but that's besides the point for now. Have you wondered whether to adjust the computer/(Youtube, etc.) player's volume or the speaker's volume knob, or both? I think I've found the answer.

    First, MAKE SURE ALL ENHANCEMENTS ARE TURNED OFF. The signal should be flat and au naturel.

    The volume on your player (YouTube, Windows Media, VLC, etc.) should be maxed. Then...

    1) If your speakers/headphones/amp/sound system has a volume controls...
    a) use the last volume control in the chain (the aforementioned sound equipment) to control the levels to your liking.

    2) If your speakers/headphones/amp/sound system DOESN'T have volume controls...
    a) use the Windows volume control (the end of the chain) to your liking.

    You may have to turn the volume down WAY LOW, but you should be pleased with the results. You'll definitely notice the dynamic range. The resolution should be improved, even with YouTube quality sound.

    From what I've read, you have to feed as much signal as possible (think of an electric guitar, for example). And also, this is a big deal, reducing the volume earlier in the chain (via software; that is, the player or the OS) reduces the bitrate.

    But whatever you do, be VERY CAUTIOUS about your ears. The last thing you want is to go deaf. I would turn your speaks down to the minimum, play something, and then raise it to one's liking. Hope this helps. :emoji_relaxed:

    Similarly, I've been experimenting with using a headphone amp. Technically, it's an alarm clock stereo, but I'm using it as an amp. Pairing it with my PC as above seems to be making a big difference for my already-great headphones. Even YouTube sounds full and open, with awesome dynamic range. And when I play CD or hi res FLAC (up to 192), these babies really sing.
