How do I go from this to actual sound file (wav)? Possible? What

Interesting.

Do you know of any research that goes into making pictures that can be easily converted into sounds? I wonder what's the most efficient method to encode audio into a valid PNG file...

delete it and download the wav file of your choice

>I'm asking because it would be cool if you could post a pic like this on an image board and then convert it to a (probably really shitty) audio file.
If you just wanted to pack audio data into an image file there are far more efficient ways of doing that.

This.

You could do this, but you'd have to have some standardization. This looks like the magnitude of a short time Fourier transform which you have to know a little bit more about to back convert (sampling frequency, sampling overlap, etc). Also, you have only the magnitude displayed here, but you'd also would need the phase info to get the time domain back from the spectra.

Of course, you could color code the channels to do this and could designate a standard code at say the top left corner that could define all the parameters you'd need. You'd have a rather large image file though.

excellent point about the lack of stereo. this pic is clearly mono (I'm guessing both channels are averaged out). I guess you could encode sampling freq as a series of pixels as well.

I remember seeing some demo of an audio app that allowed you to basically paint into a spectrograph like this and audio engineers used it to erase pops, clicks, noise etc. They basically used it like Photoshop. Not sure what the name of that thing is but it's neat. I'm guessing they use a similar algo?
