The free version is toooo limited to do a proper assessment if one wants to buy this program.
Even if one compares only 2 files in the free version it does not give complete info like spectrum analysis for it cuts of the high frequencies.
And a better explanation in the form of local help files of some of the functions would be good to.
Last year there was a mention of a trial version which was to useful to be released but if you want to sell this program you have to supply a better way to give us chance to assess it.
Whether a free or trial or full with limited days.
I feel it could do what i want it to do but there are too many out there that promise a lot and don't quit deliver.
Lets do it.
