@stan2004 posted:Any way, yes. But realistically or practically, no. That is, you might have seen threads about guys reverse-engineering how MTH stores sounds in the memory chips of Protosound engines. So given enough time and effort, I suppose the same could be done for the sounds in the Fire House. It's one of those when pigs fly scenarios!
As GRJ suggests, your best bet is to effectively disconnect the stock audio electronics and replace it with a sound-module with your custom sound. It would not be particularly expensive (say, less than $10) but would require soldering, poking around the Fire House circuit board with its tiny components, and so on. There have been many OGR threads on custom sound modules for layout accessories and rolling stock.
Above photo from this OGR thread. What you have going for you is the Fire House's existing source of DC power and speaker.
Also, you probably have in mind what the sound should be - perhaps a segment from the movie. As mentioned in the various OGR threads you can use a "free" audio editor to create the MP3 file to store in the memory card. There are "free" youtube-to-MP3 converter programs also since most popular scenes from movies are on youtube.
But, it's not plug-and-play so understandably not in everyone's comfort zone.
It is one thing to say you can modify a read/write chip that is meant to be reprogrammed. And another to say you can change a read only write once chip under a blob of epoxy, so do tell how you would reprogram the board, even if not realistic or practical. Doesn't that really mean no not yes?
Sure you can add your own sounds etc... But the integrated board is triggered off switches to do the specific sound when the engine or what ever accessory it is, is at a specific phase of the operation. Replicating that is much harder unless you are going to manually trigger it at each station. Gas station, car wash, firehouse, etc... Integrated motion and sounds. Not a reprogrammable board. G
