Software publisher's note (VinylStudio):
Hello there,
I just wanted to say that the reason why VinylStudio didn't save your cleaned-up audio is because you only have the trial version (it does put out a message to this effect when you try). If you'd like a license key to complete your investigations please contact us through our website:

Then, once you have your key, just save your tracks again and they will be saved in cleaned-up form. That is to say, the work you put into using the audio cleanup tools will not have to be repeated after you upgrade. Thanks.
