Description

I've created the raw material by blowing, mouth Close to microphone, Then I ran the 5 second long recording through edit7speed several times until signsl was 20 seconds long. I selected only a part of the new result and amplified 400%. After that I ran the signal through doppler filter Three times, amplofied again and cut out the best part of the resulting signal. Now you get the illusion of a large jet Aircraft passing at low altitude for landing.
