lol. Fanosh, you're thinking in a file by file mentality. DSP's don't see the data they handle as files. They see it as streams of information that needs to be processed. It's up to the program to provide that stream of information. Thus to start playing it opens a file, reads the data into memory, then feeds that data to the DSP as a stream. Therefore to make gapless playing, all the program needs to do is append to the first stream and the rest is child's play. The DSP won't notice the difference. It'll just blindly process whatever is handed to it.
