Audio Cassette Speed Calibration Test Tape - Free Shipping Worldwide
Description
|
FREE SHIPPING WORLDWIDE Brand new test tape for calibrating the speed of your cassette decks. Specs: Speed tolerance: 0.16% Notes 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 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:

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.
