What is the difference between DSD, DSF, DFF files?
DSD or Direct Stream Digital is a one bit recording format. DSF and DFF are 'kinds' of audio files that are delivered as downloads or read by software for playback.
DSF has the ability to hold metadata and DFF doesn't, however, some players only read DFF files.In PCM recording, DSF and DFF would be similar to having .wav and .aiff files which are both PCM
More complex answers to the above question exists, but for those new to DSD, this is a simple explanation.
