Abstract
The present invention provides a computer-implemented method and an apparatus for manufacturing an analogue audio storage medium wherein digital audio data is converted into topographical data representing an analogue translation of the digital audio data, and a laser beam is selectively applied to a substrate to form a physical imprint of the topographical data on the surface of the substrate to create an analogue audio storage medium. The medium may be directly playable on a conventional playback device such as a record player and/or used to mould further playable mediums. The invention thereby enables more efficient manufacturing of e.g. vinyl records and consistently ensures a much higher quality of analogue audio.
Claims18
A computer-implemented method of manufacturing an analogue audio storage medium, the method comprising:
- converting digital audio data into topographical data representing an analogue translation of the digital audio data, wherein the converting includes:
- importing the digital audio data into computer-aided design software (CAD software) and transforming the digital audio data into a continuous analogue signal by interpolation using the CAD software;
- and
- sampling the continuous analogue signal to determine discrete values of amplitude as a function of time to create the topographical data;
- selectively applying a laser beam to a substrate to form a physical imprint of the topographical data on the surface of the substrate to create an analogue audio storage medium.
A computer-implemented, non-transitory storage medium with instructions, wherein, when the instructions are executed by a processor, cause the following method steps to be performed:
- converting digital audio data into topographical data representing an analogue translation of the digital audio data, wherein the converting includes:
- importing the digital audio data into computer-aided design software (CAD software) and transforming the digital audio data into a continuous analogue signal by interpolation using the CAD software;
- and
- sampling the continuous analogue signal to determine discrete values of amplitude as a function of time to create the topographical data;
- wherein the topographical data is suitable for selectively applying a laser beam to a substrate to form a physical imprint of the topographical data on the surface of the substrate to create an analogue audio storage medium.
