Steve,
Honest question, honest reply...
No, you do not need this unless you want to throw away the price of admission. You can do this all for free. Think I might have posted this before, but what the hey...
I'd advise to download dbPoweramp to get all the codecs you could ever want, continually updated. I registered the thing years ago so my mp3 encoder is still active. They let you keep a freeware for all other formats, but the mp3 encoder goes down after a month. Then you use the open source LAME encoder with LameXP as the front end. Covers all the bases and has the batch processing capability.
Respect to the Frau guys for inventing mp3, but have some reservations about how they strangled out the little guys trying to offer a free encoder for mp3.
My opinion... Ages ago in the land before LAME, the Frau dudes had a monopoly if you wanted quality conversion. We used the infamous "fatboy wave" to test for potential conversion artifacts and adjusted settings accordingly to avoid garbage in the squeeze.
This day and age, there may or may not be any advantage to Frau over LAME, but if there is, only a bat can hear it.
Go for the excellent free stuff and take your girl out for the 35 yen saved.
