@ Ramakrishnan, I am afraid you have not used Goldwave.Can you specify what limitation you found in the trial version and be specific?

On the other hand the mp3encoder in dbpoweramp music converter is limited to 30 days usage, unless you buy it.

I had used the trial version of Goldwave for as long as five years for converting all my cassettes to MP3. The only limitation in the trial version is that it is limited to some 150 or so mouse clicks (commands) and normally you can accomplish your task within those limits. In the event you exceed the limit, you can save your project, close Goldwave and restart Goldwave to continue your unfinished task.

There never was any nag screen compelling you to buy except a gentle dialog that that the maximum number of allowed commands has been exeeded.I really appreciated the generosity of the developers and as a token of my appreciation, I finally purchased it.
