First of all an apology as I have, as well, posted this in layouts but thought that this group may have a wealth of knowledge on the subject. If anyone thinks that I've overstepped the mark with two postings then let me know and I'll take this one down.
So has anybody installed ambient (background) sounds on their layout, I'm sure a few have! Anyway I'm looking at doing this on a large layout and it will need at least 7 varying areas of sound around the layout. These will include a small town with quayside, a quarry, a brickworks, another small town with loco works and yard, a canal side quay, some rural areas, a small rural station. Each area will have it's own sounds relevant to that location. I plan to have these controlled by sensors (or something else) so that sounds are only 'produced' when a person is in front of that area (or a train approaches the area) - the sounds will fade as a person/train moves away'. This will mean that not all the areas will be competing with each other all the time and producing an overall cacophony of sound. I'd be interested to learn about what equipment has been used, how you installed the aforementioned, what sound files have been used and where they were obtained from and any other useful advice. Thanks very much.
I know a MERG (Model Electronic Railway Group) area group is working on it and the developer of it is an 009 Society member and member of this SIG.
I have put a fairly lengthy reply in your other post
Thanks Hugh and Graeme. I've posted a reply on Layouts.
