Using Computer Vision Technology to Play Gramophone Records
We present a non-contact optical flow based method to reproduce the sound signal from gramophone records using 3D robust scene reconstruction of the surface orientation of the walls of the grooves. The conversion of analogue data to digital data is an important task for the preservation of historic sound recordings. We digitally viewed the grooves of a record using a microscope that was modifie...
متن کاملA sound education: the gramophone and the classroom in the United Kingdom and the United States, 19201940

متن کاملReproduction of Sound Signal from Gramophone Records using 3D Scene Reconstruction
Preserving invaluable historic recordings has drawn some interest because the traditional record playback system wears out the record gradually. This paper presents a non-contact method to reproduce sound signal from gramophone records using 3D scene reconstruction of the micro-grooves cast on a record surface. Because of the unique shape of the microgroove, a planar assumption was made during ...
