The story behind DSD is also surprising as a rule known by the industry and especially by users, but that is what often happens when you lose a battle, that the mentor is not properly remembered as a winner.
DSD: when SONY and Philips worked together in the audio industry
Of course, DSD or Direct Stream Digital was an integrated project for SONY and Philips which in 1999 was adopted as the nirvana of audiophiles worldwide. Since no company had the unique ability to improve CD-Audio and its quality, their merger was seen as a step towards increasing the audio quality on CD and DVD in those years.
The preferred preference format at that time was PCM which had a sample 44,100 times per second with 16 channels. This means that they lost a certain amount of harm to the harm called music, something they were not very receptive to.
So they have released the SACD, which is much more advanced than CD-Audio, but they run into another problem: people are starting to use audio that is also compressed in MP3 and AAC. SACD introduced Delta Sigma technology along with its DSD, which still operates today thanks to great digital music.
The solution came from the hands of regular users, who found a way to extract DSD from SACD and convert it into PCM standard (widely used in standard industry) using 24-bit FLAC files.
DSD stays clean and requires high quality electronic components
