Interesting way of pitch-shifting

Apparently this is done with an image-to-audio program, and the picture has been resized as 200 times wider than normal.

edit: And of course it wouldn't be pitch shifting since the pitch stays the same, but rather, time stretching.

I have "harsh digital noise" VST for making sounds out of pictures. It's fun sometimes, plain colors with minimal variation seem to work good. I will deffo try stretching something 200 times wider

whoaaaa.... this i need to do! the first transient of his voice would make an epic riser for a dark tune, then the bit after that would be great for some moody atmosphere!

That's a very specific program, i bet you'll find it's name by going to the youtube page and checking the description. can't be bothered right now myself :D

i see... but essentially is it not just extreme timestretch? could i not just go into the warp thing in ableton and stretch the bejesus out of it?... although i'm guessing it would sound gash :confused:

Yes of course you could, but i don't think it would sound like in that video. At least in FLStudio when you over stretch something it becomes very grainy.

And I just realized that it's not resized in any way, just played slower, but as opposed to sampling interpolation (like when you play a wav across the keyboard) it doesnt change the pitch since the program reads the pitch information from the image, and the image stays the same. It's just....slower.

Realizing that just blew my mind a little o_O

I was reading about doing audio editing/cleaning up with one of these things. Because you can actually see the root frequency and all the harmonics seperately you can zoom in and delete/keep specific harmonic content.

So editing out rogue frequencies or harsh resonsnce. Interesting stuff. Must try it sometime. Also like in that photosounder thing you can 'play' pictures. Looks cool.

Also works for separating an instrument or vox from tunes, to some degree, I remember seeing this on another youtube video of the same software.

there is a program called SADIE which is a mastering suit. It allows you to edit parts of a tune just like the above. Every freq has its own colour. you can get some mental sounds by deleting/copy&pasting some of the frequencies/colours
