Here's a clip; I've got four hours of this in aac demuxed from the video source. Can this sort of distortion be removed in a useful way, leaving understandable speech? And if so, is there a way for a rank amateur to do it with free tools? Doesn't need to be production quality or anything, just easy to listen to and understand.
I see that there's a 10 day free trial of Izotope RX 7; would that be able to do anything good? Seems that the decrackle module that's been discussed here no longer exists?
edit: De-crackle does still exist; and the 10-day free trial does not allow files to be saved after editing
