Silly audiophile claims … 1

I’ve been into HiFi since I was a callow youth, well before digital audio was even being recorded by the major studios, let alone made available as a consumer format. I was thrilled with the introduction of the compact disc. So thrilled, I understand that I was the second person in Canberra to buy a CD player — a Sony CDP-101. I never even seriously considered the rival Philips unit, because I felt that settling on a 14 bit DAC was a betrayal of the format.

This little monster cost $1,200 … in 1983 currency! And it was worth every cent.

There were problems. Some of the early CDs had clearly been ported from tapes EQed for LP, and so had a sharp upper midrange that could almost part your hair, and accordingly felt rather bass light. In addition, most high quality stereo systems had been ‘voiced’ to sound best with LP, and often again added a decibel or two in the same upper midrange area.

But the freedom from surface noise, wow!

And, of course, things have just gotten better.

But there were digital naysayers right from the beginning. One thing soon became clear: some were totally clueless about the technology, and entirely irrational.

The most egregious example that I came across was one well regarded UK hifi writer who produced a lengthy article on one of the magazines. I cannot now recall the name of either the writer or the magazine, and it never occurred to me to retain it over the last quarter century. So you will be quite entitled to doubt what I write since I can’t prove it without devoting an enormous amount of time to finding it.

Anyway, the author was bemoaning digital technology for removing all musicality from the music. If I recall correctly, he was experimenting with the Sony PCM-501ES. This was an interface that allowed 16 bit, 44.1kHz stereo digital audio to be recorded using a VCR as the recording device. Pretty clever bit of kit, really.

So he’d done some live recording, and was totally unsatisfied when he played it back. I seem to recall that he used adjectives like ‘sterile’.

I don’t know. Perhaps he was right. 16 bit/44.1kHz was still pretty cutting edge stuff then, and arguably ADCs and DACs couldn’t do a decent job (which is why Philips started off with 14 bits of resolution).

But I also know that he was wrong. Because he fixed the recording (he reported).

How? He dubbed it onto analogue tape using a Revox reel-to-reel recorder, and this very act restored the musicality that had been lost by the digital process.

That’s what I mean by irrational. You can’t restore something that doesn’t exist. If this musicality wasn’t there, somewhere, in the digital recording, how could a dub restore it?

Clearly the non-linearities and phase shifting inherent in analogue magnetic tape recording had introduced a type of distortion that made his recording sound more like what he was used to.

Which software for grabbing DVD frames?

I’ve been grabbing frames from various Blu-ray discs and DVDs, with a view to setting out some more Blu-ray vs DVD comparisons. I really ought to stop the frame grabbing, and start the comparion setting out.

But I found something interesting when grabbing the last set, from Toy Story 3. As I’ve mentioned before, Disney has taken to corrupting its DVDs with a view to copy protecting them. TS3 was no different, and generally the first VOB causes trouble for the software I normally use to grab frames, VideoReDo Plus (so far the rest of the VOBs have worked fine). Indeed, this VOB normally crashes VRD, even on a ‘Quick Stream Fix’ version of this.

There was one frame in the first VOB that I would have liked to use in the comparison, so I used a different program to grab it: the freeware ‘Media Player Classic – Home Cinema‘. This worked, but the picture was obviously soft. So I tried PowerDVD 8 (now obsolete), and its frame was better than MPC/HC, but softer than VRD. Using mplayer under DOS (which is what I normally use to grab Blu-ray frames) produces a similar result to PDVD8.

Here’s a frame from the DVD:

and here’s a detail, unscaled, from the four products. From left to right, VideoReDo Plus, PowerDVD 8, mplayer under DOS and Media Player Classic – Home Cinema.

And here’s another detail:

Obviously the last is a total reject. But what about VRD vs the other two? Is VRD the more accurate, or are the other two?

If Audiophile USB cables are valid, then …

… surely we need audiophile network cables — CatAudiophile, perhaps? — to make sure the packets of precious audio digits are streamed without degradation from server to client.

But, OMG, what about wireless! If you’re streaming over an IEEE 802.11n WiFi network, then surely the air between the wireless access point and the WiFi device must be treated!

And what encryption protocol should be chosen? After all, those fragile digital bits are transformed by the security system into quite different digital bits. And they have to be transformed back before they can be heard. Shouldn’t WEP, WPA and WPA2 be evaluated for which best preserves the musicality of the source? The encryption also depends on the specific key chosen. Should one use 64 or 128 bits? The digital transport is quite different if one uses E489E3AA0A as the key instead of E489E3AA0B. Should not all the possible key combinations also be evaluated for their impact on the music?

Or maybe it’d be better to just go naked, to avoid this unnecessary tampering with the purity of the signal.

Appalling: ‘audiophile’ USB cables

The gains in low-end body and punch, midrange spaciousness and detail, and high-end smoothness alone are significant.

So sayeth What Hi-Fi. Apparently if you spend 50 UK pounds on the Wireworld Ultraviolet USB cable (I’m assuming one metre), that’s the improvement you will experience.

Seriously, what a load of crap!

What gets me about this kind of thing isn’t the vendors. As it happens, I don’t know whether Wireworld are delusional or fraudulent. Just as I don’t know the truth about the vendors of the Power Balance Bracelet. I do know that despite the ‘significant’ improvements in those airy-fairy subjective claims of spaciousness and body and detail, Wireworld have come up with two more cables. These ones actually use a ‘DNA Helix conductor layout’ that must obviously be better than than just about anything. After all, aren’t we made of DNA. Isn’t our frequency 7.83Hz (as claimed by Power Balance)?

And the prices make it impossible that they could be anything other than better. 249 UK pounds for the cheapie, and 499 for the pricey. Remember, these are one metre long USB cables, the main purpose of which is to carry, mostly, digital audio (packaged into USB format serial data) of CD-ish densities. (Or less. Did they do their listening tests with MP3 perhaps?)

As it happens, a while back I demonstrated that 44 metres of crappy audio cables, roughly joined together, could comfortably (almost) carry 3.5x CD capacity.

Neither do I blame the customers, at least in terms of regarding them with moral opprobrium. I have myself been swayed, momentarily, from time to time, by the purveyors of this kind of plastic and wire snake oil. If you’re a decent human being who generally likes people, the sheer conviction displayed by some adherents of this weird faith can be quite persuasive.

For me it is only ‘momentarily’ because I’ve learnt some stuff about myself. I know for a fact that I am very gullible in the face of a well-acted lie. I learnt that when I was a young policeman and tended to believe what the crims would tell me, until the senior policeman would thump the interview table, and they’d tell the truth. I learnt to follow the logic and evidence, not my sense of whether someone was truthful or not.

Who I do blame are the writers at What Hi-Fi, and any other writers who go along with this crap. They are being paid to deliver a service to the readers, and they are allowing themselves to be fooled by their own misconceptions, and thereby misleading their readers.

If they find themselves able to claim that a friggin’ USB cable can ‘significantly’ improve sound quality, then I would suggest that you cannot trust their views on how an amplifier sounds, how a CD player sounds. Indeed, how a loudspeaker sounds! Their opinions are worthless.

If I am wrong about this, then the writers at What Hi-Fi, or some others, can easily prove me so, and earn themselves a stack of money in the process. Just take Randi’s Million Dollar Challenge. He has previously permitted analogue cable devotees to start the process. But they’ve pulled out before getting very far.

So, come on. Prove me wrong! Prove you aren’t being paid good money by your magazines to simply spread your delusions about what you’re hearing.

The shape and colour of Se7en

On 2 December 2010 Roadshow Entertainment is releasing one of the truly great movies to Blu-ray: Se7en (aka Seven). That’t not just my opinion. IMDB has it listed at #28 on user ratings.

For ten years David Fincher had been directing music videos, apart from one perhaps inauspicious aside doing Alien 3. Then he did Se7en. It did a hundred million dollars at the box office, and turned Brad Pitt from a fast rising star (his salary was $4 million, apparently) to a superstar, and started Fincher’s real career. He followed it with it with six movies, so far, which all range from very good to superb, including Fight Club and, most recently, The Social Network.

Obviously I’ll be doing a formal review of Se7en in due course, and a Blu-ray vs DVD comparison in a few days, but there was one interesting thing that emerged when I was ripping frames for the comparison.

The Blu-ray has essentially the same special extras package as the two disc DVD version, including the three part featurette called ‘Mastering for Home Theatre’. All the extras are presented in 480i60 format.

This featurette is about how in preparing the movie for DVD the sound was carefully remixed to optimise it for the home theatre experience, and some careful colour balancing and modest reframing was performed. Stuff, basically, that they couldn’t do for the theatrical release, but could do digitally in preparation for DVD.

So we have the same featurette on both the DVD and Blu-ray. Here’s the same frame from both versions of the movie itself (DVD top, Blu-ray bottom):

In my Blu-ray vs DVD comparisons I caution that not much attention should be paid to colour and brightness differences because I use different applications to extract the frames. But nonetheless, it is usual that the colour balance taken from the same frames with recent movies are virtually identical, except sometimes for full-on red being a touch brighter for one. What we see above is a very different colour balance on the source.

And different framing.

These are consistent throughout, in the sense that there is always slightly different framing (some frames are even rotated slightly with respect to each other) and clear colour balance differences, but the differences in both vary over the length of the  movie.

And the Blu-ray choices are clearly superior. The thing looks lovely.

But there must have been some more work done after the DVD release, which hasn’t been mentioned in the Blu-ray special extras.

A Letter to the Old Country

Yesterday I received a Blu-ray player produced by a very highly regarded UK company, which shall remain nameless. This is not a cheap Blu-ray player.

But oddly it seemed rather deficient on the HDMI audio output front, not having anything like the range of output options you’d expect. I soon discovered that one setting provided only the original bitstream, while the other switched off the audio entirely, in favour of the analogue outputs.

I emailed the local distributor, who in turn emailed the UK manufacturer. This morning I received a reply. The manufacturer’s Senior Engineer’s only suggestion was that maybe I had it plugged directly into a TV. Here’s my reply (I omit the photos which would give away the product):

Ah, the home office! I do love the way the engineers back in the old country think we’re complete effin idiots out here in the colonies!

So to make it clear:

  1. the Blu-ray player is plugged via HDMI into a Yamaha RX-A1000 receiver. The receiver is in turn plugged into a 52 inch Sharp Quattron TV.
  2. in the HDMI settings for the receiver I have ‘Audio Output’ set to ‘Amp’, with both ‘Out1’ and ‘Out2’ (the two HDMI outputs) set to ‘Off’.
  3. also in those HDMI settings, I have switched all HDMI control functions off
  4. according to the manual, three major settings are supposed to be available under the ‘Audio’ menu in ‘Setup’:
    • PCM Downsampling
    • Digital Output
    • Dynamic Range Control
  5. With the above-described setup, only two options are available on the review unit:
    • HDMI Output
    • Dynamic Range Control
  6. Instead of the range of six choices stated in the manual for ‘Digital Output’ (all of which the receiver supports, of course), the HDMI Output setting offers only two options:
    • On(Auto)
    • Off *Speaker
  7. With the first option selected, the unit bitstreams out the original audio format over HDMI — for example, as I demonstrated, DTS-HD Master Audio 7.1. With the second option selected there is no audio output from the unit’s HDMI output. There is no option for PCM or any other output.
  8. The Oppo BDP-83 and Panasonic DMP-BDT300 Blu-ray players which are also plugged into the receiver are not so constrained, and all their various output options operate correctly. Indeed, that is the case for the other forty-odd Blu-ray players I have reviewed (except for a couple of the very early ones and the phat PS3 which lacked bitstream output).
  9. I’ve attached photos of the unit’s Audio menu display to show precisely what I am seeing on screen.
  10. And before our English brethren start blaming the Yamaha, I’ve just plugged the unit into a Marantz NR1601 which I cracked brand new from the box especially for the occasion. It has ‘HDMI Audio Out’ set to ‘Amp’ and ‘HDMI Control’ set to ‘OFF’. Results: identical to those with the Yamaha.

Perhaps you can pass this back to the UK and see if they want to have another go.

Hollywood sexism

Jennifer Dudley, tech journo boss for several News Limited newspapers (and a former editor of mine), has an interesting post up on The Courier Mail’s Hi-Tech Blog. Basically, she points out, the film The Social Network fails to depict any women as competent with computers. This despite the movie purporting to be about the creation of Facebook, which, she reminds us, has for three years had a female chief operating officer.

Jennifer asks: ‘Is The Social Network misogynist? And is that the fault of the filmmakers or the tech industry?’ To the extent that the movie is misogynistic, I’d go with the former. Probably not intentionally (I don’t know if the writer, Aaron Sorkin, has been accused of misogyny in his other work, most notably ‘The West Wing’). The reality is most likely that most of the main players in high innovation high tech are male. It isn’t popular to say so (as Larry Summers found out), but on most criteria the extremes of the bell curve distributions are predominantly male. The average is the same, but the bump in the curve is flatter. You get more sickeningly smart men than women (ie, when you’re getting up to four or five standard deviations to the right of the mean), and you get more astoundingly dumb men than women.

I say this as a man who is in the great safe bulk near the middle of the curve, and finds those at the extremes suitably scary.

But all this is moot. The movie is made up. Listen to Peter Thiel talk about it in this recent interview by ReasonTV. (Thiel was co-founder of PayPal, and put in half a million US dollars into a 5% share of Facebook in 2004.) Thiel is pretty dismissive of the movie as any kind of a reflection of reality, or the characters involved.

As to Hollywood, the most profound exercise in storyline misogyny I know of is its treatment of Robert Heinlein’s novel, The Puppet Masters. The book was written in 1951 and has three main characters: the spy master, his son Sam the secret agent, and Mary, another secret agent. Eventually Mary and Sam become an item, but he has to be cautious because she is every bit as deadly as he is himself. Eventually — for reasons that make sense in the book — they have a physical fight, which Sam is able to win — barely — only because of his greater size. As the story develops, Mary turns out to be even more important because she holds the solution within her to saving humanity.

Don’t get me wrong, by today’s standards the book would be viewed (especially in the later parts) as profoundly sexist, but nonetheless the Mary character is a powerful person.

The 1994 film was … well, let me quote one of its screenwriters:

A screenwriter wrote to me marveling that my name is in the writing credits of the god-awful 1994-released film Robert A. Heinlein’s THE PUPPET MASTERS. After all, I seem like a sensible enough guy, and yet the film is piss-poor terrible. He was quite relieved to find out I know quite well that the movie is awful.

That was written by Terry Rossio, no novice in Hollywood screenwriting (eg. Shrek, Aladdin, Pirates of the Caribbean trilogy, Deja Vu).

And here’s what happened to Mary:

And [Hollywood Pictures president Ricardo Mestres] didn’t like the story of the lead female, Mary. “She doesn’t have to be connected to the plot,” a female executive on the project told us, “in this type of film, the woman is just the hero’s girlfriend.”

In the end, Mary was just a boring xenobiologist in order to have an excuse to be in the picture and thus become a love interest.

So there you go. When in doubt, I say, blame Hollywood.

Free speech

I don’t normally sign petitions and join things. In part that’s because I’m weird enough to find most popular movements to be out and out wrong, or at least wrong in enough big parts to consider them more negative than positive.

But I’m pretty much a free speech absolutist, so here goes:

I for one would appreciate the right to forthrightly state that various named audiophile and videophile cables deliver absolutely nothing in the way of actual improvement.
