At present, a popular lossless music transmission medium is SACD, which is a brand-new audio storage medium and enjoys a high reputation among enthusiasts. It was jointly developed by Philips and Sony. The timbre of SACD can stand the test of the most professional and critical ears, and the fans who pursue timbre can get the greatest satisfaction in SACD. SACD uses DSD coding technology to store audio. Under the same CD diameter, the stored information is more than 6 times larger than that of CD. Many times, SACD is not suitable for rail splitting and grabbing. So the electronic version is saved as the original ISO format image. So how to extract DSDIFF(DFF) and DSF files from SACD ISO images of HD music? Please see the relevant solutions in this article. Note: The demonstration process in this paper is run under WIN 7 32-bit system.
Conceptual analysis: DSD(Direct Stream Digital) technology, also known as "Direct Digital Stream", is the coding method of SACD. DSDIFF, abbreviated as DFF, is a file suffix, and DSF is also a file suffix. They mean the same thing, except that one is Sony and the other is Philips.

The abbreviation of SACD(Super Audio CD) is a new digital audio format developed by Sony and Philips on the basis of MMCD (Single-sided Double-layer High-density Disc) jointly developed by them. Its frequency range and dynamic range are better than CD. SACD is a new type of optical disc, which is not in CD format, but similar to DVD disc, and needs SACD-specific playback equipment. SACD discs can be played on ordinary CD players or SACD players. Of course, their sound quality is different.
