Yup, the original file IMHO is already warbly (if that's a word!) ... and exactly what Ski says re: Envelope 2. In my tests I hear blips as described. :)

Dear Ski & Rounik, Thanks both for your input. Comforting to know and learn that it is ok to hear the blips that occur, due to ramp time as Ski mentions. Excellent, I learned something new :) Rounik, Warbly = a new word to describe recorded vocals, great :) Haha. Ok, I close my case. Thanks again. :) Best/Chord123
