Ordered this cassette to calibrate a Pioneer cassettedeck that was clearly slowing down all music.
A random YouTube-video helped me understand the idea about using a tape like this. I recommend this video, it's not a very polished effort, but it's also not TOO technical:
https://www.youtube.com/watch?v=60dG35aJPmY
So, in Audacity on my computer I created a 440Hz test-tone (in the menu: Generate > Tone, use the defaults), played it, and played the cassette in the deck, in my case I used the sound from the Phones-out - plugged into the same speakers as my computer.
You have to irritate your family members (or neighbours) here, as you have to play it LOUD to hear the beating of the frequencies.
This is the point were you can adjust the speed on your deck. How and where depends on the deck, and more often than not, you need the service manual to find out how to do it. Check out this site if you need one:

In my case it was a little screw directly on the motor, looking similar to this:

Of course, this is not a REALLY accurate method, but checking with my own ears, and streaming the same song on Spotify and playing it on a pre-recorded cassette, I'm more than satisfied.

Great tape! Made it easy with a guitar tuner. I have a Marantz PMD-510 Pro deck with two separate decks in one unit. It has a pitch control for each deck on the front of the unit so adjusting the pitch was easy. Luckily the both deck were pretty accurate anyway but the tape made it easy to ensure proper pitch. Thanks!!

I bought the tape because my Akai GX casette deck sounded too fast. I tried an early adjustment by taking advantage of the same music recorded in a tape and a CD, but it is only a provisional solution with a fairly high margin of error. Finally I have ordered the adjustment tape. I turn the motor adjustment screw looking at the frequency measured using a free phone app, "Frequency Counter", while the adjustment tape is playing. Now the fit is simply perfect. Thanks!!

I never knew I could use my guitar tuner to calibrate the speed of cassette decks until I found the Duplication.CA. website. Bought 2 calibration tapes. The 440Hz was easier to use for calibration WITH my KORG Pitchblack Custom tuner. A 3150Hz tone is also included in the tape for use with a Frequency Counter. I didn't bother to test my machine using the 3150Hz tone on my DMM's frequency counter since the 440Hz worked well with my guitar tuner. I would recommend this calibration tape to anybody working with cassette deck speed calibration. Guitar tuners are getting cheap these days. IT WORKS!

First off, many thanks to the previous reviewer Marcel for the tip on the location of the motor speed adjustment.
I just finished up using this tape and the level calibration tape to calibrate one of my decks. It worked perfectly.
I used it along with a computer based instrument tuner called fmit (Free Music Instrument Tuner) for the 440Hz tone. I connected the output of my deck to the sound card input. There is another similar tool called "lingot". But fmti seemed to work a little better on my system Ubuntu Linux).
I also used the frequency analysis tool in Audacity to double check the accuracy. Audacity can also be used with the 3150Hz tone on the tape.
I highly recommend this tape.

In my case it was not straightforward to adjust since when starting one of the double decks it plays at 3200 Hz and then slows down to the correct speed, within a few seconds but I think I've got it correctly adjusted since playing both decks at the same time they stop with 15 seconds difference. The pots are difficult to reach and very sensitive. I used Daqarta on PC to adjust and at the same time I aligned both waves, so I presume azimuth is also corrected. Now I'm restoring my old Pioneer CT-606 deck and as this one has a heavy flywheel it should be easier to adjust. Yes the tape works as expected.

hi this tape work ace in any 4 track head set up
not for any 6 8 track recorders there are space's
where the tape is not recorded i have a tascam 238

it's a ace tape for the money i am super pleased
with it but there one small thing i had to change
the black parts that push the tape as the tape
was not spooling into the take up reel right

The tape arrived in perfect condition. I used the 440Hz tone with a guitar tuner to check my tape deck speed. Also by using an oscilloscope I was able to measure the delay between the left and right stereo channels. The amplitudes of the left and right channels were different by about 2dB but I attributed that to difference in alignment of the test tape recorder and my cassette deck. I decided to leave my head alignment alone. This is a very useful product and I highly recommend it.

The tape came as expected within 3 weeks.
My Sony TC-RX611S has a replacement drive-motor that should be on te correct speed, but I thougth it wasn't. I needed to test this correctly. And with this tape I was able to check this. The deck indeed drives to fast. 3,5% to be exactly.
So now I orderd a correct spare motor that I can adjust following the Sony instructions. I will do this with this tape as a guidance.

Excellent product! I fitted a Teac deck and some pretty good Sony walkmans. In my case I adjusted them with free software from Techmind.org, http://www.techmind.org/audio/index.html
With the Tuner (Frequency-counter / instrument-tuner)
I also used wow & flutter meter(WFGUI wow & flutter meter) by Alex Fred from http://www.ant-audio.co.uk/index.php?cat=post&qry=library
The latter was suggested in a Techmoan Youtube video, https://www.youtube.com/watch?v=0G2kU1e9Cpo
I used the second one, for the first one the 440hz tone of the cassette is recommended
The only inconvenience was with the shipping company that they did not make the shipment with tracking, but duplication.ca responded immediately, they told me that if the product did not arrive on a certain date they would send me another one at no cost, this was not necessary, since It arrived without any problem. Totally reliable and safe purchases in duplication.ca
Thank you very much from Mexico.
Thank you duplication.ca!!!

Excelente producto! Ajusté un deck Teac y algunos walkman Sony muy correctos. En mi caso los ajusté con un software libre de Techmind.org, http://www.techmind.org/audio/index.html
Con el Afinador (Frequency-counter / instrument-tuner)
También usé medidor de wow & flutter(WFGUI wow & flutter meter) de Alex Fred del sitio http://www.ant-audio.co.uk/index.php?cat=post&qry=library
Este último fue sugerido en un video de Techmoan en Youtube, https://www.youtube.com/watch?v=0G2kU1e9Cpo
Yo usé el segundo, para el primero es recomendable el tono de 440 hz del cassette
El único inconveniente fue con la compañía de envío que no hicieron el envío con rastreo, pero duplication.ca respondieron de inmediato, me dijeron que si no llegaba el producto en determinada fecha ellos me enviarían otro sin costo, esto no fue necesario, ya que llegó sin más problema. Totalmente confiables y seguras las compras en duplicatión.ca
Muchas gracias desde México.

Replaced the belts in my Awia ADF770, then used the test tape to check speed using a windows based software wow & flutter meter. New belts, a clean amd lubriation fixed flutter issues, but still seeing speed variations. Have ordered a new capstan motor - will replace and retest. The Duplication test tape arrived promptly, was well packaged and worked great - could not complete the repair without it - nice job!
