When I loaded new audio file into Audio Cleaning Lab version 3 program creates associated peak file, and its OK. But when I loaded later changed file whith this same name as earler when program creates associated to the earlier file peak file - program uses old peek file.In meantime I changed this file in another DAW editor (in this case changed all in this file - sometimes I chaned its played time). Now when program loaded old peek file, when I add some time with silence of the begining file, program trimm end of file (saved only lenght of file saved in old peak file). To avoid this I must(!) before loading each file manually(!) cleared all program cache. When I do this, program on the next load file which I mention earlier into this DAW editor, program again recreates from scratch correct associated peak file. I suggest, when I closed project file, program delete also associated peak files which are used by audio file used in this project.
