It's been at it over 24 hours and only 2/3 through, CPU is 2.53GHz, soundcard on motherboard, which I believe utilizes CPU for some functions. WavepPad is using 98-99% of CPU.
This file was recorded by another program from LP and went through several de-clicking sessions in it before I decided to try to see what WavePad could do with it.
I can't imagine it is supposed to take this long...
