What is the core principle behind Haber's sound recovery?
The central idea is to treat the groove on a phonograph record or cylinder as a physical landscape. When sound was recorded, it was encoded as variations in the depth and width of this groove. My approach uses optical scanning to capture a high-resolution image of this groove. Then, through careful digital processing, we interpret these variations as if a stylus were tracing them, effectively 'playing back' the original sound waves.
