Why would anyone use HD Tracks for Downloads?


I really enjoy hi-res computer audio music files I've downloaded from Liaison in Europe. These files were recorded direct to digital and I download them as 24/96 FLAC or WAV files. There is an obvious improvement in dynamics, soundstaging, noise floor and detail over CD that make it worth the small increase in $$.
My understanding is that all, or at least the vast majority, of downloads offered by HD Tracks are nothing more than existing older standard resolution analog masters transferred to PCM or DSD format digital files. Standard resolution recordings transferred to a hi-resolution format cannot produce hi-res music files. An analogy is transferring a steak served on a small plate to a larger plate; the steak will still taste the same and there is no improvement in taste. Music originally recorded on a multi-track analog reel-to-reel recorder will have limited dynamic range, a higher noise floor, a limited frequency response and less detail than the same music recorded directly to digital.

I know there currently is a lack of major artists taking advantage of hi-res, direct to digital recording of their music. Most of the truly hi-res music seems to be coming from lesser known artists. I've found that i Trax in California and the Liaison Music Shop in Europe are 2 good sources of true hi-res recordings.

So, my question is to those that have downloaded supposed hi-res music files from HDTracks: Are you disappointed by the sound quality of your purchases from HDTracks? I would think you would be, since I believe you're listening to standard resolution files that should sound no better than CDs or records you may already own of the same material.

I'm very leery of buying HDTracks downloads not only because of the above, but also because they fail to list the source of their downloads; there's no mention of whether they're simply transfers of standard resolution masters or are recorded direct to digital and actually are hi-res.

I'm interested in readers' thoughts on avoiding standard resolution files advertised as hi-res.

Thanks,

Raymonda,

I actually do have decent experience with analog, having utilized vinyl playback for a decade or more using very good quality turntables and cartridges but never ultra hi-end equipment. I enjoyed a lot of good music on those systems and thought the fidelity, at the time, was very good. I also listened for many years to a friend's reel-to-reel system playing copies of master tapes of Steely Dan, the Moody Blues and the Marshall Tucker Band albums. Those sounded better than I had ever heard a system sound up to that point. I have no doubt that good analog recordings on both vinyl and reel-to-reel, played back on high quality systems, can sound exceptionally good.

20 plus years later, however, I decided to set up a computer audio system (laptop running JRiver and connected to an Oppo 105 as a DAC via a NAS and wi-fi network) and discovered that, if the recordings were made direct to digital by a competent engineer, the result is highly accurate and the most 'in the room' realistic that I've ever heard thus far. In my opinion and to my ears, recordings merely transferred from the original analog masters are not nearly as satisfying since they have a higher noise level, lower dynamic range and less detail. That 'in the room' illusionary impact is lessened in my experience.

I do not wish to carry on the analog vs. digital debate; to me, the the debate has been settled.

Zd542,
Yes,I consider'standard resolution' to be anything at or below Redbook CD quality. I would classify vinyl, reel-to-reel and cassette tape as standard resolution.

You stated: " For analog recordings, there's no limit on resolution. Quality will vary depending on how well the recording was made. It can range from very high, better than CD quality, to very low quality."
I definitely agree that quality will vary depending on how well a recording was made. However, claiming there's no limit on the resolution of analog reel-to-reel recordings ignores the fact that it has a high noise floor and its dynamic range is limited to 60-70 db while digital has a dead-quiet noise floor and has a dynamic range limit of 90-95 db.

However, my reason for posting this thread was not to dismiss analog as a music source. Analog users know how good it can be.

Looking back, I think it was HD Tracks email ads that spurred my posting. Their site is filled with good artists and music that I want to buy but know I shouldn't because the recordings are not up to the standards of true hi-res. I think, at best, their recordings are transfers of the original analog masters to digital PCM and DSD formats. But I cannot be certain because they give absolutely no information of how their so called 'Hi-Res' titles were created. I'm assuming they're just transfers from the original analog masters since I know of none of these artists re-recording their music directly to digital and qualifying as hi-resolution audio.

I think my frustration at HD Tracks not identifying their process, and not making a distinction between analog transfers and direct to digital recordings, spurred me to post this thread questioning their claimed hi-res offerings.

I am certain that music recorded directly to digital by a competent recording engineer, and played back through a high quality system, results in a musical experience that the vast majority of Audiogon members would classify as excellent. I think this because I've achieved these results using several different direct to digital recordings.

I think my main point is that companies like HD Tracks selling analog to digital recordings as hi-res will only lead to disappointment from buyers since they will be unable to hear any differences between their existing music and those falsely claimed to be hi-res. The sad truth is that they'll be right, there is no difference, since the music was not recorded direct to digital.

Hopefully, more artists will become aware of this important distinction and begin recording digitally but companies selling analog transfers as hi-res titles certainly won't help.

I hope I adequately clarified my thoughts,
Tim

Dolby SR is in the 90-95db ratio of signal to noise. I think you are looking at Dolby B systems of the 80's Analog noise reduction has come a long, long way since then. Try listening to Circus Monkey from Walter Becker. This was recorded totally in analog using Dolby SR. I doubt you will be troubled by any noise floor. Too bad that you can only get Becker's album on CD. It would be great to have an AAA copy.

I'm not bashing digital at all. As I said, if it weren't for digital I would not have the business I have today. Last night I had a job, which was a multi-track live record of Hot Tuna. I just couldn't afford the cost if I ran analog, nor would I be able to easily set up and tear down equipment or mix it within the time frame that my customers need. With digital it is wham, bam thank you! And, yes, the results can be fantastic......but I dream and drool over the thoughts of a SOTA multi-track analog rig. But that turns into a lot of money and a lot more work and time.

So, beyond the digital vs analog issue....to my ears transfering well recorded analog to high rez digital is worth it. But I wouldn't let go of the analog master cause digital can not capture everything that analog can.

BTW, where in the world did your friend get those analog masters? Was he a big time studio engineer that had access to these masters? Those are some big name artists that he worked with. Very impressive. I'm envious!!!!!
BTW, it is pretty easy to see whether HD is using CD and upsampling. Just look at frequency graph. Filters and brick wall filters tell all.

And if they are...well it is consumer fraud and a class action needs to happen.
Raymonda,

You stated: "Dolby SR is in the 90-95db ratio of signal to noise. I think you are looking at Dolby B systems of the 80's Analog noise reduction has come a long, long way since then.

I'll take your word that Dolby has lowered the noise floor on analog recordings and thereby improved the Signal to Noise measurements. Very expensive reel-to-reel master recorders utilizing Dolby A or SR noise reduction are capable of S/N ratios of 60-80 db. 24 bit/96khz PCM digital recorders are capable of S/N ratios of 144 db.

Since you are a recording engineer, I'm sure you're aware that SNR and Dynamic ranges are closely related. In my last post, I specifically stated the Dynamic Range of analog reel-to-reel recordings is in the 60-70 db range but should have stated it was possible to achieve a dynamic range of 80 db if very expensive reel-to-reel analog recorders with Dolby A or SR are employed. However, even relatively inexpensive digital PCM recorders are capable of capturing dynamic range measurements in the 90-95 db range.

But I think our discussion has devolved into a debate of analog vs. digital, which I think we both wanted to avoid.

I'm very glad to learn that analog master recorders are improving by lowering their noise floors and increasing their dynamic range utilizing the newer Dolby SR technology even though it's expensive, probably not universally employed for mastering and will need future innovations to match direct to digital SNR and dynamic range capabilities.


You stated:"BTW, it is pretty easy to see whether HD is using CD and upsampling. Just look at frequency graph. Filters and brick wall filters tell all."

I know about brick wall filtering showing up on a frequency graph that is a telltale sign of a digital recording but I don't think HD Tracks even makes the frequency graphs of their music available. Are you aware of any frequency graphs available from HD Tracks for their available titles?

It is difficult, for a layman such as myself, to determine which hi-res sites offer the highest quality hi-res music files. I have been utilizing the inefficient method of trial and error thus far and only discovered that music recorded directly to digital sounds the best to me. I find the superiority in SNR, dynamic range and detail of these files to be easily identifiable and obviously superior to CD recordings.

The best downloaded file I've purchased thus far is from Liaison Music Shop of a Jennifer Gomes album called A Thousand Shades of Blue. It was recorded in front of a live audience and my 24 bit/96 khz FLAC download sounds better than any CD on my NAS. It is dead quiet with outstanding dynamics and incredible detail that creates a solid and stable soundstage giving the realistic illusion of the musicians being in the room.
Now that my computer audio system is up and running well, I'm on the lookout for more high quality music downloads like this but I'm finding the process difficult and frustrating.

I think I'm just looking for information, tips and some direction on finding good hi-res downloads of good music. Maybe you're right that good analog recordings transferred to digital will give good results. It would definitely expand the available music available for me to buy. I may start by taking a chance on that Walter Becker Circus Monkey album you mentioned.

BTW- My friend got the reel-to-reel master copies from his older brother. His brother wasn't involved in the music business and I never learned where he obtained them. He was actually a drug dealer and I wouldn't be surprised if a crime was involved.

Thanks,
Tim

Tim,

You ran with a tough crowd back in the day.

Hifi News and Review's music section has does a frequency and spectrum graph of digital down loads, which can be useful. I don't do too many down loads, although that may change. When I do it is straight from the artist and they are true transfers.

Again, try Circus Monkey. Not only is it a good recording....although a bit overly compressed with some limiting but the music is great. It will be something you will listen to repeatedly.

Also, Jerry Garcia from the Capitol Theater in 1981. It is an 88/24 transfer of a multi-tracked live show. The only limitations are the mics that were used. You don't have to be a Dead Head to appreciate this recording or music. After listening to that, you will agree that you are glad it was transfered to hi-rez digital. Also, there is little to no limiting and most likely little compression on individual tracks during the mix. The wav looks fantastic and the way every mastered 2 track should appear.

You can get it at Jerry Garcia's web site.

I think we agree on hirez digital being very good. It's not a dog vs cat or chocolate vs vanilla thing......you can like both!
