Before we start the show, I need your help.

We're currently making an episode about the history of audio formats.

The show will cover everything from wax cylinders to vinyl records to CD-GD's.

There's also going to be talk about 8 tracks, mini discs, cassette tapes, real to real,

that's, hit clips, iPods, and anything else we can find.

If you have nostalgic, happy, or even angry or frustrating memories about any of these,

then I'd love to hear about it.

In a second, I'll tell you where to go to record that, but first,

here's some questions to get the wheels turning.

What's the best or worst or weirdest audio formats that you remember?

What was it like to use it?

What did you love or hate about it?

To record your message, go to the web address, high.20k.org.

You can also find that link in the show description.

You can also email a voice memo or a high quality recording to high at20k.org.

If you do, we might just use your voice in the episode.

Thanks.

You're listening to 20,000 Hertz.
