SoX decodes as the first step - so it will not losslessly concatenate MP3 files. ffmeg can do it, though. Something like: ffmpeg -i "concat:file1.mp3|file2.mp3" -c copy output.mp3 or create a text file with one source file per line like this: file '/path/to/file1' file '/path/to/file2' file '/path/to/file3' and this command: ffmpeg -i list-of-files.text -c copy output.mp3 > (The ability to unwrap the combined mp3 into individual files > isn't a requirement, but it would be a nice thing if possible!) If you document the timing (length) of the source files, mp3split should be able to be used to separate them again. But it is not a built-in feature like it is with mp3wrap. ------------------------------------------------------------------------------ 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@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/sox-users
