What is DXD?
DXD is short for Digital eXtreme Definition – a sound encoding scheme for professional use that was developed for editing high-resolution recordings because DSD is not ideally suited for editing. DXD is a PCM-like signal with 24-bit resolution sampled at 352.8 kHz – eight times 44.1 kHz. The data rate is 11.2896 Mbit/s – four times that of DSD.
Back in 2000 when Sony/Phillips first introduced the Super Audio CD as the next best music format, they could not have envisioned the impact that it would have on the audiophile community. Audiophiles exuded the merits of SACD and wanted even more. Unfortunately having two similar formats, DVD-A and SACD, made people hesitant to adopt the newer technology. The main difference between the two formats was the added value of copy protection that SACD had to offer. This was also its downfall. Adding copy protection made the format more complex to record and edit. Sound quality wise, SACD had the higher bandwidth as well as having dual layers for multichannel and conventional stereo programming. As the wave file is the native format for conventional Red Book CD’s, the SACD is comprised of DSD files at l-bit/2.8MHz sample rate. One technical solution for recording, editing and mastering DSD for SACD production was a new format developed by Digital Audio Denmark and Merging Technologies and a
