Batch add silence and repeat OGG files

Sorry about that, I could have saved you some time there but I didn’t know that MSDos was also restricted to integer arithmetic. I had posted a Bash general script for adding silence to the beginning of a file here: Batch Scripts with other programs and yes it uses “bc”.

More generally, yes Python is much more flexible and powerful for this type of scripting, and if you really want to you could even write a full GUI front end.
