Bug description: I need to significantly increase the wind sound in Wwise so that it can be heard at high speed in the exterior view. It works well when the view follows the plane.
However, when the view becomes fixed, for example to follow the plane during a flyby (Showcase), we hear the sound of the wind as if we were following the plane right next to it. In fact, in my opinion, the external sound of the wind should be modulated according to the speed of the camera, not the speed of the plane! But there is no variable giving the speed of the camera…
There is indeed an example of wind attenuation: aircraft_player_outside_wind. But the settings don’t seem to work…! How can this problem be solved?
Here’s my video… I’m in an exterior view of my plane, watching the flight from the airfield. In Wwise, I’m in connected mode. When I increase the volume of the wind outside the plane, I can hear it very clearly from my position at the edge of the runway. This doesn’t seem right to me…
You have several way to handle this. From the simplest to the more advanced:
1 - Setup an attenuation
Your wind_sound_outside has no attenuation set up. You can use the one designed for this specific case and your sound will be attenuated based on the aircraft position
2 - Use an SPP_DISTANCE RTPC
This will let you customize a bit more the attenuation curve, still using the distance between the camera and your sound source to modulate the sound.
3 - Use an RTPC with a custom local variable
You can write your own attenuation logic (based on DRONE CAMERA SPEED TRAVELLING or CHASE CAMERA SPEED for example) and write the value you want to use to modulate your sound in a local variable you then use in an RTPC.
From what I’ve just tested… all the solutions, except the first one, allow me to modify the sound of the reactor depending on the distance… but not the sound of the wind. And the first solution doesn’t work, as I said in my first message… despite my attempts to modify the elements contained in “Attenuation”!
Your last image suddenly enlightened me: I didn’t think that attenuation could also be applied directly to a sound. So I had the misconception that only containers could be attenuated. And I realized that I was trying to adjust the container’s attenuation upstream, when in fact there was another attenuation on the sound itself downstream. Under these conditions, of course my upstream attenuation wasn’t working, because it was the sound itself that was being taken into account by Wwise…!
Now that I have a better understanding of the system… it works exactly as desired, and I thank you once again, Sylvain, for pinpointing the problem!
