Stelsel voor het registreren en/of weergeven van een digitaal pulscode-modulatie audiosignaal.

摘要

Disclosed is a digital audio recording apparatus for formatting digital audio data and recording formatted data on a digital recording medium, so that digital audio data having a first sampling frequency and other digital audio data having a second sampling frequency being twice the first sampling frequency can be reproduced in both a reproduction apparatus having an operating frequency for digital-to-analog converting the first sampling frequency and that having an operating frequency for digital-to-analog converting the second sampling frequency. The digital audio recording apparatus transforms the digital audio data into transformation coefficients in a frequency domain, the transformation coefficients are formatted using one of predetermined recording formats. Corresponding digital audio reproduction apparatus reproduces an analog audio signal from the formatted data, based on an operating frequency for D/A conversion, a formatting method of the formatted data, and a sampling frequency of the audio signal contained in the formatted data.
