The challenge -- to try to recover as much as possible from a totally
corrupted wax-cylinder, capturing Johannes Brahms playing one of his
Hungarian Dances. The original recording was made in 1889 by an agent of
Thomas Edison, in Brahms's appartement in Vienna. In a first attempt, the
program managed to recover sufficient information to carry out the MIDI
reconstruction of a passage, in which Brahms departs significantly from
his score in free improvisation. Subsequently, the programs technique has
been refined for application in more realistic situations.
The basic denoising procedure consists in separating a noisy audio file into coherent and noisy components.
