Converting different lossless audio formats using free software

• SACD ISO to DSF

To convert SACD ISO to DSF use ISO2DSD Use Sony DSF output mode because DFF doesn’t support metadata.

• FLAC + CUE file

Use CUE Splitter from Microsoft Store.

• Metadata TAG

Use Mp3tag. Supports flac, dsf, wv…

• DFF to DSF

Use DFF to DSF conversion utility from Signalyst. Scroll all the way down to find the utility. Be aware that the software works in command line, so you’ll want to use ISO2DSF wich allows to use ‘Send to’ menu to sequentially process list of selected DFF files.

DSD64 = 2.8224 MHz
DSD128 = 5.6448 MHz
DSD256 = 11.2896 MHz
DSD512 = 22.5792 MHz

Because of the nature of sigma-delta converters, one cannot make a direct comparison between DSD and PCM. An approximation is possible, though, and would place DSD in some aspects comparable to a PCM format that has a bit depth of 24 bits and a sampling frequency of 88200 Hz.
