This last bit worries me. I don't see how that would be possible unless some sort of marker was placed between the n'th and (n+1)'th file. But then, it'd cause some sort of horrible sound when you played the file... if indeed you ever intend to play such a file... Why would you do this? If you just want the binary content merged into one long file, surely a normal file copy/append would do? Or you could zip the set of files into one file. -- Jeremy Nicoll - my opinions are my own ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Sox-users mailing list Sox-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sox-users
