This helicopter sound design was created at fl studio, in the sytrus synthesizer. The sound consists of four layers. 1. Sine wave frequency of 44 hz. Simulates the low frequency noise of propeller blades. 2. White noise passed through the svf filter. Simulates the noise of propeller blades. 3. Saw wave. Simulates the sound of an engine. 4. The sine wave. Imitates a high-frequency whistle of the engine. Various modulations are applied to all waves through the envelopes of the synthesizer. Next, the signal on the mixer channel is processed by a multi-band exciter and equalizer. Then a signal was sent to two channels with delay processing. One of them imitates reflections. In the lower-middle frequency range. On the second in the upper-middle frequency range. As you approach the sound source, the volume parameters of the direct and reflected signals are automated, low pass filter, pan width and equalization of direct sound. The helicopter performs strange maneuvers, as if making constant circles during the approach to the listener. I did not seek to create the veracity of these maneuvers.
