Hi Mike,

OK, I'll try to give it a shot. Reading the headers looks reasonably easy, but the exact multiplexing of the data words does not seem straightforward.

My idea was to write draft code in Octave that I'd later port to embedded C (or if need be some DSP asm).

Not that I know of.

Honestly it sounds like the most straightforward path is to convert the
DSD audio into PCM encoding using another tool (I have no idea if any
free software exists to do that), and read PCM samples into Octave.

But if you want to write an Octave function to read a DSF file, please
go ahead, and share your progress, maybe others are interested also.
