The issue I've had is the fact The I'd does not play till the end, ignoring the FCC req of 10 minutes. And, being some what of a Linux newby, I'd like to understand your input below,"$~> sox newline_file(x) id_file newsline_file_id(x)(where 'x' denotes which newsline file, since the one long file is chunked up into several pieces.)"
I'm aware of the partition ID in the ARRL news file, but don't know how to take advantage of it automatically. Does your command line address this? If so how? For sure, I'm missing something here.
