Dash 9 new engine sounds

[_o_OOOO_oo-Kanawha]

Updated: I do have a small problem now, my ES44's now have the same engine sound as the Dash 9. I believe the ES44 sound pack I installed a while ago is partly aliased to the Dash 9 sounds, but the ES44 uses different environmental sounds. It is even more alive than the Dash 9 with all those hisses, clicks, creaks and rattles.

Nope, ES44AC 10-Engine Sound Pack (is that?) didn't alias to Dash9. What I did for my own use, and posted the formula here on RWA, is how to alias Dash 9 to ES44AC, because default RSC's sounds of either ES44AC and Dash 9 are (quite) the same. Maybe you aliased, and don't recall.

Doc, on my USA testing install, your 10 engine sound pack is not yet installed. It still has the old RWA ES44 sound pack, and most of the repaints are still using the old sound pack.

I must really sort this mess out, since it is nice the have small sound variations between different engines of the same series.

I suppose it wouldn't be wrong if the Dash 9 and ES44 sound the same sine they have the same prime mover (Diesel engine): they both use Gevo. Only more strict noise pollution and air quality regulations might have lead to diferent hood insulation and/or exhaust silencers etc. in the newer ES44, which change the overall 'sound image' of an engine.

kanawa, That is completely false. The ES44s use a GEVO-12, Dash 9s use an 7FDL-16. There is a huge difference in the sound too.

Thanks for the clarification.

This means it is wrong to have the engine sounds shared by different models.
Now I must really install Doc's excellent 10 engine ES44 sound pack to give the ES44 its own distinctive Gevo sound. The Dash 9 can keep its own new soundpack offered by this thread's OP, and burble nicely away in idle.

Love those high quality engine sounds!
