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.

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.

Très bon produit, livraison assez rapide compte tenu de la distance avec la France, bon prix.
Cette cassette permet de régler la vitesse et le gain des platines correctement.
Je suis très content.
