ORG.SLM:
This utility converts DSD audio between Sony DSF (.dsf) and Philips DSDIFF (.dff) container formats, including decompression of DST-encoded DSDIFF files and ID3 tags in both containers.
Parts of this project are based on the SACD Ripper project, particularly libsacd and libdstdec. See https://sacd-ripper.github.io/ for more info.
Tested on Windows using MinGW 4.9.3 and MSVC 2013/2015. You will need pthreads-win32 to build using MSVC.
