My objective is to *automatically* concatenate two .wav files together.
I know it's simplistic to say: cat file2.wav >> file1.wav, and I know software exists that can append one wav file to another with some manual cutting and pasting, but I'm looking for software that would allow me to *automatically* perform a concatenation of two wav files from a UNIX command line. (Actually, I'd prefer to invoke the concatenate command from a batch process set up behind a cron job.)
Does software exist for UNIX that would allow me to concatenate wav files together from the command line? Remember, in my case, humans cannot perform the concatenation. The process has to be *completely* automated.
file1.wav is a recorded message that says "This is a test"
file2.wav is a recorded message that says "of the emergency Broadcast System."
Via a batch process-- invoked by cron-- I want to automatically concatenate file2.wav to file1.wav and have the resulting concatenated .wav file say: "This is a test of the emergency Broadcast system."
I hope this task is possible...Thanks for your expertise, and please email me for clarification or if you need me to expound on any issues.
