Dear all, I am using sox for automatic, scripted file generation. One step is a mix of several input files. It may happen that - by configuration - only a single input file remains for that mixing step. This cannot be handled by sox, because sox _requires_ at least two input files and quits with the message "Not enough input filenames specified" I understand that at least one input file is necessary (for finding the target length, sample rate etc.), but why does sox fail when mixing a single input file?
Probably because it's simpler to write programmes that assume the user means what they say. So if you ask sox to mix several files, it is written assuming that you will provide more than one. You say you're using a script to drive this. That means you are in control. Your script can - surely - determine that there's only one input file and adjust the sox command(s) you're using accordingly. -- Jeremy Nicoll - my opinions are my own _______________________________________________ Sox-users mailing list Sox-users@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/sox-users
