Cassette tape tone

[Jagwah]

A lot of cassette tapes used to have 5 or 6 very short tones that would sound shortly before the recording began. I assume it's some.kind of eq calibration tone but I can't find info about it.

Any one have any info or know what the tones were called?

Cheers!

I never heard tones on audio cassette. Perhaps you are referring to the tapes for computer programs?

Nope. The tones played from low to quite a high pitch over the 5 or so notes, and together lasted about one second. They weren't blanks either, store bough tapes with legitimate albums on them. 80's and 90's. If no one can help, with some digging I can find my own on some old tapes, hoping to understand a bit more about it though.

Never heard that. Maybe it was your cassette player.

I have no memory of this either and I was quite familiar with both commercial albums and blank cassettes when I was a kid.

Maybe it's a country specific thing? Like a standard?

Ok maybe it's an Aussie thing too not sure but wanted to do a short video with it so if I find it which I should I'll post it here, cheers.

You beat me to it! Very interesting, this was in 1982 and not sure how long it was used for:

"Recording a short test toneburst at the beginning and end of the program material on the cassettes, to detect for any loss of audio frequencies in the audio spectrum. These tones are recorded then read during the duplication process to detect if there is any loss of any audio information"

And here's what it sounded like:
