Yup - You're right. I got tangled in multiplying by two and dividing in half, and re-doubling again... or one of those...

We can hear up to around 20 kHz, but need to sample at twice that when recording as per Nyquist. And have to double that again for the second audio track...

So now you have a pretty good "audio series" with the Christmas jingle one plus these three [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-6ca20be9-c402-4ed9-927e-97dfc3ed4e9e/4174.contentimage_5F00_1.png:16:16]

This is awesome. It is somehow like the "opposite" of using XY mode on the scope to draw pictures to music.

I think that the 44kHz is more referring to stereo sound; so two independent channels each running at 22 kHz. Since your setup is mono, you would be comparing the 8 kHz sample rate against 22 kHz for CD.

Hi Gough,

OK pretty cool but can you get your walkman to act like an Oscilloscope?

Fantastic project! An oscilloscope as a music player blows my mind. The title is the best. Video game music for a video game title. Too funny!

If you thought that was the end of my shenanigans, think again:

Great demonstration of understanding sound and using equipment in a most unexpected way![View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-6ca20be9-c402-4ed9-927e-97dfc3ed4e9e/contentimage_5F00_930.png:16:16]

A great sound, especially coming from an oscilloscope. I like the idea of a month long holiday more though.

Great work. I think the slightly dodgy result even added to the project!
