Related perhaps, but not strictly DCC sound. Has anyone ever used/tried the systems like Surroudtraxx? I.e. the surround sound system that I believe uses transponders for loco location and plays sounds around the layout? It seems JMRI also has a module for this.
Si, please move if there is a better forum for this.

I took part in an op session once where the layout had such a system. It sounded exactly like I would have thought: the sound passing from one spot instantly to another. The owner of the layout kept trying to hype the system (sounding more like he was trying to convince himself it was great, more so than any of us) and nobody running there was having any of it.
I don't understand the merit to something like that in an era of 'plug and play' sound that can be small enough to stuff even into a N scale locomotive in many cases. The only time I'd see merit to it is in the case of you not having enough room in your locos for ANYTHING else.Last edited on Thu Apr 19th, 2018 12:23 am by Lee B

Lee,
Thx. Do you have any idea how large his detection blocks were? That might have something to do with the sound jumping around.
I am exploring/investigating the idea as I am considering N scale, but still want BPRC and N is pretty small so not a lot of room.

No idea, sorry. I agree that the sensors might have bene very far apart. I know he didn't have many speakers, though. I think they were about every 5 feet or more. It sounded like the locomotives were teleporting from one spot to another, as if in a science fiction movie.
It was very distracting and several people discussing it away from the owner all agreed it would have been better to have no sound at all.

The BLI Rolling thunder is a way better system.
The only thing that's being broadcasted is the bass tones.
I would like to build something similar with a Bluetooth transceiver in the loco, connected to the speaker wires, and a subwoofer under the layout.

That might work as a supplement to the sugar cube speakers in the locos themselves!

I do it the same way, together with battery RC control. Do you already know this thread: The Replicant. ?
Also see here: First 7/8th scale loco

Here's the 'Low Pass Filter' originally Posted in >> THE REPLICANT << Thread.
- - - - - - -
I mentioned a while back, that >> THE REPLICANT << would be using a 'LOW PASS FILTER' as part of it's operation.
I had a chance to search out a suitable candidate for this the other day.
It's very simple to connect up & operate.
A soldering-iron or board-plugs are not even needed, as it has nice chunky screw-terminals.
It cost me £2.97p inc P&P and will arrive here soon.
If you use the search-term 'LOW PASS FILTER BOARD' on eBay, you will find it very easily.
More on how it will be used, to follow.
Here it is.
Put simply, this 'Low Pass Filter' allows the sound-spectrum to be split into 2 parts.
This 'split' is variable between 30 Hz & 300 Hz.
Sound is essentially 'Non-Directional' below about 150 Hz depending on perception.
Tiny little speakers in locos cannot reproduce anything like these frequencies properly.
Since these frequencies are 'Non-Directional' they can be heard 'everywhere' from just 1 suitable speaker.
NOT a 'sub-woofer' as such & nor are such speakers suitable either, they 'split' way to low at maybe 50 Hz ish.
Si.
