Brand new test tape for calibrating the speed of your cassette decks.

Specs:
- 440 HZ A tone (for quick check with instrument tuner) (or MIDI note 69)
- 3150 hz tone for setting speed with frequency counter and checking wow and flutter
- Recorded in stereo, not full track

Speed tolerance: 0.16%

Notes
The speed variance to move a half tone from A 440Hz to A# at 466.16 Hz is 5.9%. That's a lot .Most cassette decks should be operating well within half or a third of that range. But if you're doing tape copies you need a much tighter tolerance to avoid cutting off the music or having a huge empty space at the end of the sides, especially on longer tapes of C-50, C-60, and longer 

We have compared the speed of our test tapes against old test tapes from Sony, TEAC, and Nakamichi. Our test tapes play back the 3150 Hz tone with comparable variance as we found with those old test tapes. The variance of our tapes is +- 5 Hz or 0.16%. When adjusting speed your target is 3145 to 3155 Hz. But most of you won't have a frequency counter so we've included a 440HZ A tone to calibrate with any guitar or instrument tuner. You should be able to get within 0.5% using the 440 Hz tone.

If you want to dub your own tapes consider this:

1% speed variance on a 30 minute side is 18 seconds per side
2% speed variance on a 30 minute side is 36 seconds per side
3% speed variance on a 30 minute side is 54 seconds per side 

This item includes free worldwide shipping by the post with a tracking number. Delivery time is usually 2-3 weeks but could be longer. Tracking is not available on shipments within Canada.

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.

Product is as advertised. Purchased this test tape to adjust a deck I cleaned up and after changing the capstan belt, which gives one confidence that the deck is working well.

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!

English translation:
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!!!

Original Spanish review:
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.
Thank you duplication.ca!!!
