Marco123 Hi! Whatever I tried, I always have this quality with Voice Pitch Shifter, Preserve Formants: https://vocaroo.com/i/s0kRM1FxUwz8 I can guess with a lot of effects on it will generate such, But this is already with only pitch +5%
Marco123 Little more info: I bought the Plus - Commercial License, It applies also with process file I have a blue yeti microphone, and it happens with raw and processed recordings.
