I have an Olympus DS-2 and I would like to take WAV recordings of talk radio and convert them to DSS. I figure this will make the files much smaller and quicker to transfer. I see that the Switch Plus handles DSS. I tried to download a trial but as soon as I do I am told that my trial is up (I have had the free version of Switch for some time). How can I try the Plus to see if it fits my needs before purchasing? Will my idea of WAV to DSS work? Thanks. Wayne
