Right. We _can’t_ give you pre-made events because if any two developers leave them in place then we’ll have duplicate-ID events and the AI planes won’t work together properly.

Thanks Ben. I was thinking that there was a pre-made file structure as well. I was able to open the “Mixer Routing” window (CTRL+5) to see the groups. ;^)

Thanks for filing a bug. The “AI and user aircraft are the same” _is_ a special case.

When we load your plane as an AI, any external sounds attached to the un-processed bus have to be moved to the processed bus, because your “pre-processing” of an interior recording isn’t okay for the interior of some -other- plane. But we don’t do this if the AI plane is your plane because we can’t change the routing without screwing up the user’s plane. In this special case (user’s plane is the AI plane) I think we just let the AI plane see the real ‘inside’ ratio.

You need FMOD 1.08.14 I think. The project should be blank except for mix buses – it does not come with sample events.

I’m happy to share my project. I’ll file a bug with the project attached and referencing this comment thread.

I discovered today that the atennuation bug is not present if the AI aircraft are the same aircraft that I’m flying. In that case, the sound heard from the outside of my plane *is* the exterior sound, and the external sounds as heard from the interior of my plane are correctly muffled.

Also, I was wondering why the other jets don’t sound like mine at idle, and it seems to me that they idle at lower RPM than mine.

I am guessing that we need to use an older version of Studio. (1.08) as the download on the FMOD site is for 1.09 and when you open the project it states that it must be migrated and when it does open in Studio, the project is blank. I was expecting the project to open and look similar to the sample in Studio. Is this not correct?

Yeah, it’s new to us too – it’s very likely you’ve hit a bug in X-Plane or something.

Here’s what is _supposed_ to happen: when we evaluate the inside ratio for an AI aircraft’s event, we always set the inside ratios to 0. Thus if you have separate inside/outside recordings, the AI should always play its outside engines into the exterior processed bus, giving you all and only the processing that the user’s plane creates.

Our Cessna is probably just not handling the busses properly; it’s a very old project dating back to mobile – I’ll check with Chris re: it’s behavior.

If you get inconsistent loudness using your aircraft for both AI and user aircraft, you may have hit a bug in X-Plane and I’d be interested in a reproduction case if you can share it.

cheers
Ben

A couple questions though. I’ve noticed the sound from the AI planes comes out a bit muted, that is, if you put the camera near an AI jet, it doesn’t sound as loud and clear as when that jet is the one you’re flying. I think that doesn’t happen when you use the Cessna as AI plane. Is there something wrong I’m doing? As per your recommendation, in my project all engine sounds are routed to the Exterior Processed/Aircraft bus, and there’s a snapshot with intensity coupled to the inside_ratio dataref, which muffles the Exterior Processed bus, but it shouldn’t mute the exterior sounds when the aircraft is used as AI, right?

Also, I tried being inside the Cessna and the sound of the other airplanes is heard exactly the same volume and clearness whether I’m inside or outside the Cessna, as if the sound isolation was not working. With my project is the same, as if the AI planes are not routed thru the right bus.

Any ideas? Please bear with me here, this is all new to us! 🙂
