. . . . How could I remove REVERB from a recording? . . . .
Assuming you mean an existing audio file eg mp3, wav, etc then this is not possible. It is like trying to seperate the ingredients for a cake after they have been mixed together.
Thanks johnebaker for your reply, and more so for including an explanatory article. I am always interested to read more about my new pet project (digitizing cassette tapes) but I am clueless about how to search for references, especially when I am ignorant of what terms to use to search by. This is why the PDF manual of Audio & Music Lab Premium and this forum are very important for me.
