I remember someone making 3D prints of waveforms like this at Shapeways. I wasn't sure the resolution was there for it to actually work in the opposite direction, but they probably sold a few. |

That's cool, they're pretty neat looking. |

To do full words they'd have to be pretty long, but they might say positive things like a Yoko Ono art exhibit if your'e familiar with her stuff. Seem to remember Lennon talking about climbing a ladder and at the top it said "Love" or something positive. I'd picture these maybe giving little positive messages like hope, love, etc. |

Waveforms are nowhere near high enough resolution to scan and play back unless they are stupidly long. Think about the length of a LP groove, and the resolution that it is "scanned" by using the needle. |
|

Or think of it in terms of sampling - 40 kHz gives full spectrum of human hearing, that's 40,000 samples per second. An iPhone 16 for example with a 48MP camera will have a horizontal resolution of something like 10,000 pixels max. So the phone will be able to photograph and capture 1/4 second of audio by scanning a waveform. |

What you need is not the waveform but the spectrum of the sound. And that is widely known to exist, there are apps that you can get that allow you to print out a spectrum and then scan it with the phone to play back the sound. |
|

Well, your link shows how this would work. Don't need to do any impressive math here, any representation of a squiggly line can be used to modulate a signal to generate sound. A Jackson Pollock painting can be used to generate sound. |

Not sure I'd need a whole 1/4 second though just to say "peace" or "love" though. Also not proposing this as a replacement for a 192 kHz sample rate, 24-bit depth digital audio sampling machine, this would just make dinging noises and maybe words to such an extent that the visitor would say "Hey, I think it just blew me a kiss!" |

Interesting thing about the 3D waveform scan is you might have to play around with it, scan if from different directions making it a further interesting interactive art piece. |

I'm thinking you may actually be able to do something akin to mp3 file encoding to both make it take less space and make it fit better on a sculpture without being long and narrow. basically what mp3 encoding does is split the sound up into frequencies and modulate each frequency at a significantly lower rate. |
|
| |
Good analogy. MP3s get rid of all the audio spectrum stuff you can’t hear anyway as a human. The sculpture’s job would be even easier, just to sort of vaguely have you make out what the sound or short one syllable word it is. |
|
| |
But being sculpty while doing it. |
|
| |
I love it. It needs a different format to represent sound. Anything will do as long as it has many various, continuous shapes or sizes. You could paint a picture that encodes music. You could paint a picture that encodes music that encodes text. |

I was hoping this would be an actual sculpture like the Thinker or somesuch that would move his mouth and face while singing somehow. |
