Gapless playback of FLAC files.

I use a Blu-ray player to send my FLAC files to my dac. The audio sounds very good but I run into an issue when two FLAC files are supposed to be continuous, with no break. My Blu-ray player (Sony UBP-X700) adds a second of silence, even when the FLAC files have no break at the end. This doesn’t happen when I play the files on Foobar2000, but I prefer to have a freestanding transport for sending files to my dac, instead of using a computer.

I heard that Panasonic makes a Blu-ray player that can do gapless playback, but I like the RCA Coax SPDIF jack on my Sony player and the Panasonic doesn’t have that. I wonder why it’s so hard to get gapless playback.

Any ideas? (All I want is to send gapless FLAC to my dac.)


You only gain something from gapless playback if two or more tracks are intended to play with no interruption at all. A brief silence ruins this effect.

If I use a computer as transport, the only way I can connect to my dac is with USB. My blue-ray player allows for a spdif, hdmi, or toslink connection cable.

Where does the blue-ray player get the flac files from? Where are they stored? 

FWIW, wheather the blue ray player (the renderer) gets the flacs from a PC or directly from a USB stick it still won’t play gapless. 

The player gets the files either from an optical disk that I insert (CD-R or DVD-R) or a USB drive or flash drive. A Red Book CD can also be used in the disk drive. Of course, the gapless issue does not depend on this. My player just doesn't do gapless, but others are gapless (which is the point of my original message).

To me is so unbelievable that in 2023 there are still players out there that cannot play gapless correctly (a paramount feature to me)...get a proper streamer as the Bluesound Node and the problem is solved
