I (over at Photosounder.com, home of the program that turns sounds into images and images into sound) have just started a new challenge. It consists in denoising a 115 year old sound by editing its image generated via Photosounder using Photoshop/GIMP/whatever you got or by writing a dedicated image processing algorithm.
The winners get a free license of Photosounder worth $140/€99.

Full Version: Graphical sound denoising challenge
Looks like you made a mistake: your daisy_bell_full.flac is already denoised.

Damnit you're right. It's not actually denoised, but I messed up during the conversion. Something always has to go wrong...
For anyone interested, the winner: Graphical sound denoising challenge results.
