[bash] ecalength fileB.wav --> fileB.wav: 240.658s (4m1s) Then do... ecasound -i:fileA.wav -o:fileB.wav -y:240.658 I just downloaded and compiled "sndfile-concat" and it's much easier. It will even glue files of different types and bit rates without having to convert them first (but not files with different number of channels). http://www.mega-nerd.com/libsndfile/sndfile-concat.c You might want to use ecasound for "splicing" differnt files into other files. Of course, it's also an (complete) multitracker, effect processor (and much more actually). Rocco
