Custom sound effects for train system

Hello, I’m working on a train system based on a real life train and I’m wanting to try replicate the sounds from the real life train onto the copy of it in Roblox. I’ve got no clue where to start and I have zero experience working with sounds and sound effects.

I’ve recorded some sounds from the train which includes sounds of:
Accelerating
Decelerating
Track nosies
Fan sounds
Door closing warning sound (Beeping)
Door unlocked sound (Beeping)
Dynamic braking sound (Some kind of buzzing sound when the trains slowing down)

Theres probably a few more and some that I don’t want such as,
Wind sounds
People talking, walking, moving and making other sounds
Automatic voice announcments (Announces next station, going to use the text to speech feature roblox is planning to add.)

Some sounds are layered over each other (So you can hear both wind sounds and accelerating at once in the same recording) so I was thinking split each sound into their own track and import it to roblox and play as expected.

The recorded sounds may not be the best quality, but would there be a way to try improve them to the best quality the can be?

Edit 28/02/2025
My solution to getting the sounds for automatic voice announcements at its absolute highest quality was to connect to the train’s induction hearing loop (Audio from the train basically plays out of my phone) and just screen record my phone while that’s playing and then just extract the audio from that.)

Recording at the earliest time when the service is available for the trains you are recording the audio of is probably your safest bet since there’s not a lot of people, but that varies because i’m from hong kong and here trains usually start their first service everyday at 5-6am. I also like to put my microphone very close to the train speakers for announcements and door beeping and stuff like that.
Or just about any time when there’s the least amount of people like the last train, but make sure you don’t miss your stop where you are closest to home, or closest to transport to home

as for announcements try to put the microphone as close to the floor as possible, if you can or maybe try to stick it next to the door, which is what i like to do

The recordings aren’t that bad, they’ll do (I think) but I probably just need to learn some audio software to edit each sound into its own track and improve the quality of them.

The automatic voice announcments are the ones I don’t want as I’ll use the Roblox text to speech feature which is on the roadmap for mid next year

i have no idea which software to use to filter out background noise :joy: I hope my previous comment does help though

Not really sorry, but I’m sure I can probably edit these sounds some how with ai or something lol
