I've found a pretty kick-ass piece of software regarding spectral editing.
It's able to separate different instruments from a mono (or stero) recording with the help of the user. It's like cutting up a sound in GIMP, looks amazing. I think it could be of much joy for KX Studio userbase.
I already showed this to Audacity guys, asking if they could make use of that code and workflow, but I guess until that's done it's good to have the standalone version availabile. I wasn't able to run this, I'm not very good at building random packages. I hope you guys can do better and maybe include this marvelous project in the repos. I guess if it get more users, we could make noise and make it's developers get working on it again. Or make the A-team implement that functionality in Audacity (that'd rock!).
So here the project page. I think the demo video does great job there:

Here's my forum post in Audacity's land, if you're excited and want to bump that up:

Also there's a much simpler tool for converting sound to image, and the resynthesing that sound from the image (spectrogram). It has some neat unconventional uses like sound design, or printing sounds out of an inkjet, to scan them and play back later. I've run that and I'm trying to get some interesting sounds out of it. It's pretty fast (in the -s mode: sine synthesis). The demo material is pretty inspiring in my oppinion. I think this one is worth having in the arsenal too. Also, I'd love to see an LV2 instrument that'd use that tech to play back image files (RGB ---> LR?) as audio samples.
