I bought a program called Polderbits about 10 years ago and almost paid to upgrade to the 64 bit version when last month it suddenly went into a trial mode time out and the web site wend dead. I tried something like a half dozen others, all unsatisfactory, when I stumbled on WaveShop. I played with it for a few days in the limited time I had and soon found that my loss proved a real gain. I now have a much faster and user friendly 64 bit program that will do more such as join files. I have been through a support issue and have no choice but to rate it tops in every category.
It is like a trimmed version of Audacity. There are no pitch, tempo change plugins, so it is useless for me. It is only good for basic wav editing.
Ah when you find a great program you also find a great programer. Every conversion there was no issue. Used other audio programs for playback to test the conversions that were done in this outstanding editor and it was a flawless playback. Not overbearing in looks of the application which is perfect.
waveshop works great
