what is sdif
The SDIF format is a sequence of frames, similar to chunks in the IFF/ AIFF /RIFF formats, but not strictly compatible. Every frameâs length is a multiple of 8 bytes. Every SDIF file or stream must begin with a small opening frame.The body of the file or stream is a contiguous sequence of time-tagged frames, sorted in ascending temporal order, with multiple types of frames allowed in a single file or stream.The most recent version of this format, SDIF-3, is the standard multi-channel hardware connection employed in DSD recording systems.he body of the file or stream is a contiguous sequence of time-tagged frames, sorted in ascending temporal order, with multiple types of frames allowed in a single file or stream.
