I wanna try this one out asap

Open your sound in Photosounder then just press C to copy the image to the clipboard or click save and save as a bmp

Well, I'll try doing some easy tutorial. The non-Photoshop part (i.e. in Photosounder) is easy, it's all about opening and saving files, it's the Photoshop part that I guess is more confusing, correct?

this is huge.... do you think it'd work for isolating vocal samples? Imagine the bootlegging potential!

Well, not the way I did it, that's like microsurgery, you can spend an hour just to obtain a few seconds of change.. There would be other ways such as shown in another of my videos in which the images of the publicly available song's instrumental's image is subtracted to the full song's image to obtain the isolated vocals, but you need the instrumental for that. You probably could do it too on songs with very repetitive beats by just looping the clean beat..

You are a legend.

This is exactly what I hoped for in melodyne but it never delivered. Well played.

I have a nice vocal sample but it has some horrible background noise. I have struggled to remove it using filters and EQ's, would this help me?

Only had a quick look at work.

Well, it's not that straightforward to explain cause it's like new concepts on top of each other. The first one is the image-based filtering one. A sound is turned into an image that represents it, the image is modified by the user, the modified image is compared to the original image and the original sound is modified (filtered) to reflect the changes done to the image.

The rest builds on that as it's entirely an image processing problem. So then you've got a graphical brush tool that smart-erases lines to replace them with background, and a harmonics modifier that reproduces the effect of that brush tool onto each instance of harmonic overtones, and that magnet modifier to snap to the nearest lines. So that's just for erasing an harmonic instrument like that synth line, since what we want is the opposite result we calculate the difference between that and the original image to get the image we want.

Well, everything is shown in the new video I posted in this topic a few days ago. All the steps are there.

Yeah, how to do this was covered on my blog a few months ago :

Check the contest result in the second link. That's substantially better than anything I've heard with regular denoising.
