Using Image Processing to Play a Vinyl Record
Vinyl records were the primary medium for music and sound reproduction for the last century until the recent rise of digital formats.
Analogue sound wave-forms are stored as physical bumps and deviations located in the grooves in which the stylus is run through.
Unfortunately, many older mechanical recordings are at risk of considerable damage through further contact with a playback needle.
The aim of this project is to make use of modern affordable technology, such as scanners and microscopes, to create a photographing copy of a record and use image processing to track the grooves, extract the analog sound waves and recreate the sound digitally;Â thereby reducing risk of further decay.
