The usb eLicencer is necessary for using this program, especially if you want to use it on multiple devices.

The usb eLicenser is sold seperately directly through for approximately $27.99, or through a third party merchant. Upon purchase, I'll email the unused 'download access code' and the unused 'activation code' that Steinberg attached to this product. I'm offering it at a reduced price because I didn't need to use this for my music project and I'd rather it not go unused and have someone else enjoy using this great product while at the same time recoup at least some of the money from what I had originally paid for it, which was almost $600. This was just purchased in December 2018. This item does not require shipping, I will email the product download access code and the product activation code directly to the purchaser of this item within 1 to 3 days or sooner upon purchase. This is the download version of Steinberg Wavelab Pro 9.5 Audio Mastering Suite (most recent 'full version'). It wasnt that long ago when there were quite a few dedicated audio editing and mastering programs available, but over the years, one by one, most have gone.
