OK, so this might be a bit offtopic for this board, but it's very cool.
The "other" hobby for me is programming, and one of the main things about programming is the "demo scene" - basically where teams of guys program cool graphical effects demonstrations on computers...
... or in this case, an oscilloscope!

I guess many people have seen things like Lissajous figures generated on 'scopes, but this is very clever. |

where can you download the wav file?
you could make a special wav file for testing soundcards with so you can see problems visually. |

Hello Sirs,
Foobar do it. No need to get a plugin. |

| Most amazing! What's the setup? 2 sound cards? Or is it just 2 channels? |

One soundcard is used to generate the display... one channel controls X and the other controls Y. On the Youtube video, I guess the soundtrack is dubbed in afterwards.
I've also tried this under a software X-Y scope, specifically the one in GoldWave. It works but looks very flickery as there's no phosphor persistence to stabilise the image. |

I just tried it out. I had an earth loop that made things a bit fuzzy. A dark room helps.
Strange watching your headphone amp clip into a square when you turn the volume up too high.
I had trouble getting nice clean corners on the cubes, even on DC coupling.
This would be an interesting way to test amplifiers, run this through the amp into 8 ohms and look at the clarity of the CRO image. |
