Here, now you can have the benefit of a day’s research and tweaking.
Windows 10 File Explorer provides vast quantities of information that can, at times, be overwhelming.
My goal here was to simplify the interface and provide only what I needed. There was lots of good help on the Web and many options. This is what I decided to do, at least for my five machines. Fortunately, much of this is the same from Windows 7 and Windows 8.1, so there is lots of documentation out there, but it’s not all in one place. Here’s my attempt. I WILL BE USING REGISTRY MODIFICATIONS. IF YOU ARE NOT COMFORTABLE DOING THIS, THEN DO NOT DO IT. Make a backup. There are other ways of making things work if you wish to take a different approach, but I will leave that exercise to you. YOU ARE ON YOUR OWN. I cannot help you if things go awry. I have tested this on two desktops.
Here is a rambling discussion of my experiences and thoughts on the Windows 10 upgrade experience. I am now happy that I’ve done it. I’m still learning about it, but work is progressing with few (if any) glitches. Cutting to the chase: a worthwhile upgrade at the right price with few downsides. (more…)
This has been updated 2015-07 and now 2005-11. We ordered a new 1022 viewer from Arnold/Flexmag as the 2007 Sigma finally gave up the ghost and the 2011 Sigma that I had as a spare is not as good a performer for this application. As of the end of November, we are still awaiting a response from Sigma. Overall, I am quite pleased how well the “fresh” Arnold unit works and it appears more sensitive than the older 3M unit I had even when it was working well. This is now my top choice. It is not perfect, but fits the budget better and performs much better than the newer Sigma. It is also faster than the Sigma ever was.
Please look here, but there is still good information, below.
Two ways of seeing tracks on a tape are listed here. We’re collecting more in the comments. (more…)
My wife has been putting together a slide show for the Aurora Historical Society and I’ve been helping with some of the photo cleanup. She did the difficult part of culling a couple of hundred images out of 10,000 that are sort-of organized by different people over many years. We came across this gem.
This summer , we have completed the project we described at the end of last summer. We began the summer of 2008, with Robert working every summer to some degree since. Michael split the work with Robert in 2009. More commentary below the graphic (UPDATED 2013-08-31) after the break.
High-quality hand tools are a must for working on high-end tape machines. I’ll discuss some of the specifics in other articles.
The tools that Studer supplied (when required) were made by PB Baumann, now PB Swiss Tools in Switzerland.
My preferred supplier (for North America) is Tool Lady. She also sells Wiha tools to complement the PB line. Barbara Christy, the original Tool Lady succumbed to cancer on April 11, 2015 after a four-year battle. Her daughter Rachel Straight has announced that she, in the guise of Tool Lady II, will continue the business.
I was interested in the progression of the Scotch/3M tape boxes over the years, especially after someone contacted me because his father was in the picture on some of the 1960s tape boxes.
There are many factors that affect the ability of people like us to digitize tapes for you, our clients.
One of the most difficult issues to balance is the physical space that different formats take up, the ongoing maintenance of these formats, and, to be brutally honest, their return on investment.
What we discovered is that some of the machines we were archiving for future use would not work when they were brought out of storage. Rubber parts, capacitors, and lubrication are probably the most prevalent causes of failure. We have said to clients more than once (with a wry smile), “Yes we can probably restore your tape, but first we need to restore a machine.”
Manufacturer and maintenance depot support for various formats is waning or fully discontinued. Parts are hard to come by, and good machinists with an interest in doing this are either non-existent or very expensive.
I have used 35 mm single lens reflex camera systems since about 1965 when I started out with a Honeywell Pentax Spotmatic, and a 50 mm f/1.4 lens. In 1966, I added to that a Spiratone 35 mm f/2.8? wide angle lens and a Sun Zoom 70-210 mm f/4.8? telephoto. Later I added a 400 mm f/6.3 preset lens.
In 1977 I moved to Canon F-1’s and ended up with a nice system of Canon prime lenses 17 mm f/4, 28 mm f/2.8, 50 mm f/3.5 macro, 85 mm f/1.8, 135 mm f/2.8, and 200 mm f/4 and three F-1 bodies. Late in the life of that system I added a Tamron 500 mm f/8 mirror lens which was not what I had hoped it might be.
After a brief flirtation with Canon EOS, I moved to Nikon in 1990 and have been shooting Nikon ever since. I had more lenses and bodies than I ended up knowing what to do with, going from 20 mm to 500 mm f/4. Over time, I owned six Nikon film bodies, five DSLR bodies (so far), 11 prime lenses (all but one a Nikkor), 9 Nikkor zoom lenses, and 5 Nikkor teleconverters! In 2003, I bought my first D100 digital SLR and have had two of those, a D200, and now shoot with two D7100 bodies.
Thinking back on this, I spent 12 years with the Pentax/Spiratone system, 12 years with the Canon FD system, and I’ve been with Nikon for 24 years.
I was somewhat happy with the 18-200 mm lens on the D200, but it didn’t make me happy on the D7100. I suspect that the 18-200 was perhaps the limiting factor for resolution on the D200, at least at some focal lengths! (click the image for a larger view)
There were a few functions that were not operating as well as I had hoped in the home network now that we have DSL and Cable again and two VOIP telephone lines, one configured per incoming service.
Since we have double NAT which is generally a bad thing, I needed a work around to fix NTP time updates that had broken. This did the trick on the main router (downstream of the modem/routers). Note that I’ve added this to the Connection Hub (DSL Modem/Router) as well.
And while on the subject of router tricks, this port forwarding scheme was suggested by TekSavvy to keep the VOIP Adapter working well on a SageMCom wired port.
I received an email requesting clarification on my 1980 AES Preprint about the use of voltage audio distribution vs. power matched audio distribution for analog audio signals.
The confusion seemed to be about equipment being rated for driving a 600 ohm load. Yes, most professional audio equipment will drive a 600 ohm load, but might (repeat might) lose a small amount of headroom doing so. The better reason to be able to drive a 600 ohm load is to drive long cables which might create slew-rate limiting if they load the output to the extent that they slow it down. It’s all about current. In fact, merely being able to drive a 600 ohm load may not provide enough current to drive very long cables. (more…)
While this post does not specifically pertain to audio tape restoration, it does pertain to keeping originals and copies safe, especially in heritage buildings.
This article is prompted by a devastating fire in Aurora, Ontario, Canada, where I have lived for the last 10 years and also from 1981-1983. On Friday, April 11th, there was some roofing work being done on the 135-year-old Aurora United Church. Roofers were using hot tar and allegedly some sort of open flame. Humidity is not high in the winter and we had a cold one. The church roof structure (and much of the ceiling structure of the nave) was wood. Hot tar, flame, low humidity, wind, and very dry old wood do not mix well, and the results, sadly, were predictable. The church is now a ruin. The fire department spent 4-5 hours with up to maybe 7-8 master streams running into the attic and other parts of the structure.
When I made a 30th anniversary photo book to give my wife, I nearly killed my mouse hand working in Lightroom. Also, a mouse is a difficult way to do fine adjustments of the cursor. (more…)
We are currently working on some un-published tapes for a major Canadian folk artist. We have a 7.5 in/s 2-track stereo recording that was one of (if not the) first studio recording of this artist from circa 1972.
At some point, this tape was played on a 1/4-track machine that injected hum onto the left channel. Here’s what the magnetic viewer showed:
In a discussion on 2012-01-20 in the New Studer list, Todor Dimitrov posted the differences between the record and repro boards between a 1/4-inch and a 1/2-inch two-track A80RC repro cards. Here are the changed components for the 1/2-inch version. There are five different oscillator versions in the manual, including one for 1/2-inch.
REPRO: R1=100K; R21=330
Note that the mechanical modifications between 1/4 and 1/2-inch tape handling may be substantially more complex in terms of tuning the transport. I know of no definitive notes on this subject. [Added 2013-10-09]

I had previously posted in the original (and now reconstituted) Studer List on 2008-04-24 that there were other extant and possible modifications. Here is a slightly edited and reformatted version of that post:
I have just transferred three 8-track cartridges and I thought I’d share my thoughts about these transfers and what are realistic expectations for these cartridges. (more…)
There is a recurring question as to what is the best way to set azimuth for playing a tape. Many people assume that using the test-tape alignment is best. Well, that makes another big assumption: The recorder used a proper test tape alignment. While that can be the case, it usually is not. (more…)
Pete Hammar and Tom Fine came across a great site detailing 40 years of music statistics in a series of pie charts for each year. I thought it might be interesting to show this as a graph:

I had the first failure to capture an entire concert in my recording career. I had become complacent and considering that I had new (April 2012) Li-ion batteries for my Sound Devices 722 recorder, did not think twice about recording a concert on the approximately 50 Wh 6-cell packs. Well, one failed, and did so spectacularly without a warning. I did not notice the in-process warnings, because I do not wear my headphones during the whole concert. I try and take in the concert so that I can then see what’s missing in the studio. Here is what the after-the-fact results showed:
I have been having a lot of fun recently looking for specific software tools that avoid having to purchase multiple licenses of the high-priced programs. Here are a list of my picks of free and low-cost software tools. I am sticking with Samplitude Professional for audio and Adobe Photoshop and Adobe Photoshop Lightroom for photo-graphics. The other alternatives, however, are wide open. (more…)
The long-term maintenance of digital formats that I do not get a great call for has become a burden. While I would like to have all formats available for all people, I have such a backlog of analog, that I will not be accepting digital-only projects in many formats that I used to.
The formats that I am currently committed to transferring are:
—DATs with two options:
-straight transfer where we listen for glitches and look at the waveform for glitches (four Tascam DA-20 MKII)
-error-logged transfer where the machine logs all of the errors it has concealed (Sony PCM 7030)
—PCM-F1 on VHS or Betamax (multiple machines and multiple ES-601 and PCM-F1 decoders)
—Sony DASH (3202 or 3402) 2-channel reel (two each Sony PCM-3202 and PCM-3402)
—MiniDisc (normal stereo in regular and HI-MD, but not porta-studio multitrack; multiple )
(Sony MZ-RH1 Hi-MD Minidisc recorder with USB download; Sony MDS JE-530 and two other MD players)
—Digital Files on CD, DVD, hard drive, USB drives, etc.
The ubiquitous phone plug, especially in the 1/4 inch (6.3 mm) size, is extremely confusing to the uninitiated. I was at a church today where I struggled to get a video to play properly in advance of an event in a few days.
The church had a PC and two 60-inch diagonal video monitors (another story). The audio was fed to the good-quality 16-input mixer (Allen and Heath, I think) from the PC’s headphone output.
In the video, there are two places where there is speech and the music is faded into the background. When played in the church, the voice disappeared! This created some angst coupled with erroneous assumptions. I hope this post will perhaps help solve this problem for others. (more…)
I was at a church today where I struggled to get a video to play properly in advance of an event in a few days. There were issues with the application of a TRS phone plug (another story).
The church had a PC and two 60-inch diagonal video monitors plus a smaller monitor for the choir. There appeared to be a powered splitter/amplifier at the balcony console to split the HDMI to the two big monitors, with one cable running down each side of the church. I believe there must have been a second two-way splitter (hopefully another powered splitter/amplifier) to tap off the feed from the right main monitor for the choir monitor.
When I arrived, the PC was set up for 1024 x 768 display with the HDMI output mirroring the laptop built-in display. The laptop built-in display was capable of 1366 x 768. The slide show was a 16:9 WMV file. I tried expanding the display to the widescreen resolution and it was fine on the PC, but the monitors would not sync.
There have been rumours that Nakamichi used a different cassette standard than the other manufacturers. This is not really the case. Everyone thought they were using the same 3180/120 or 3180/70 microsecond equalization as specified in IEC Pub 60094-1, 1981. There is further discussion from 2010 here.
As I understand the history, both Nakamichi and STL in the late 1970s discovered that when they made calibration tapes based on the published time constants in the standards, their response showed that the then-common BASF alignment tapes were approximately 4 dB high (hot) at 16 kHz.
It is assumed that BASF, who made the calibration test tapes made an error in calibrating their reproduce heads’ response in one of two areas: (more…)
There was an off-line discussion about VHS-Hi-Fi tracking and breakup in Hi-Fi playback and how to correct it. I brought Jim Wheeler into it, and he agreed to write this article. —Richard
I invented the automatic tracking system in 1976 but it is pricey. If you want to pay about $2,000 for a pro-VHS machine, you can get true auto-tracking. Manual tracking works for most tapes. If not, there was a problem with the recording VCR. Alcohol is not good for cleaning heads and tape guides. I always use Xylene and you can buy Xylene at hardware and paint stores. Do not use Xylene on a pinch roller! Have your window open when you use it. I sniffed Xylene for over 30 years and am still okay–okay–okay….I recommend using Xylene for cleaning all components in the tape path except the pinch roller. I recommend Isopropyl alcohol for cleaning pinch rollers. [Some of us are using Formula 409 on pinch rollers—it depends on the pinch roller and its application—Richard] (more…)
The format page for 0.15 inch wide tape has a drawing (click for large version) that clearly shows that mono cassettes have one wide track and stereo cassettes split this track in half and add a small guard band. Most mono cassette recorders follow this format. It turns out that the mono Marantz PMD201 uses a two-channel head and records dual mono. Most other mono recorders seem to follow the standard.
While this is a theoretical problem, few if any good mono recorders are available for reproducing these tapes anyway, so most of us in the domain transfer field use good quality stereo machines for all cassette transfer work.
UPDATE 2012: While it is often possible to sum the channels if the Dragon finds proper azimuth, on many low-quality tapes this proper azimuth is not achieved. Now that azimuth correction (at least the time delay portion) is available for a reasonable price in iZotope RX2 Advanced, I have found that after correcting for time delay between channels that I can now sum both (if they are worthy of it) and reduce the noise prior to applying the noise reduction plug-in. (more…)
David Dintenfass kindly sent me an article from the October 1959 issue of Popular Electronics which says, in part, that RCA plans to have 65 titles in the stores in their new cartridges by Christmas 1959. Other manufacturers were shown to be making compatible players. (more…)
I have recently been looking to replenish my supply of D5 (Decamethylcyclopentasiloxane) and did not have much luck receiving replies to my email. Others have reported difficulty finding this in quantities smaller than a 55-gallon drum.
I found a promising listing for cyclopentasiloxane and when I queried the supplier, he indicated that the analysis was 97.5% decamethylcyclopentasiloxane and the balance being octomethylcyclopentasiloxane. I suspect that is more than good enough for tape work.
In the 2007-2008 school year, my son Robert asked me why we did not have all our family images in the computer as there were some that he needed for a report. Since this was a project I had desired to undertake for some time (but who has the time), I responded with “I’m very glad you asked, what are you doing for a summer job?”
As of September, 2012, the bulk of the work has been completed and here are the statistics:
