| Remove unwanted noise from recordings, LPs etc Our current audio denoising efforts started with 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, we have 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 (sound examples). Subsequently, we have refined our technique for application in more realistic situations. Brahms wax cylinder examples:
Original (AIFF, .WAV, .snd), denoised segment (AIFF, .WAV, .snd), and denoised segment with super-imposed MIDI (AIFF, .WAV, .snd). |
