Our workaround for converting wav to mp3 with a BATCH-Script works now – We got no helptful information from syntellect, how BATCH-Scripts with parameters are triggered. To ensure that the parameters are correctly identified by the BATCH-Script, they must be written between double quotes – the problem was, that a string already has to be between double quotes. To write double quotes within a string, you must write two double quotes, as we found out (trial and error…)
e.g. “Hello “”world”"” for: Hello “world”
Unfortunately this information neither is in the syntellect help files nor was syntellect able to tell us…
