Play without putting any toilets in your park
do that for a couple hours while recording the audio
Play normally and mute the game's audio
Play your recording

would that be good enough?

lol good one

aside from not being synched with what's happening (like the merry-go-round wound not playing when you're next to the merry-go-round) it would kinda work, wouldn't it?

there's ambiance sound files and ride tracks but that doesnt solve anything
ive clicked the ear for a ride just to listen to its music and avoid toilets and it's a bliss till i close the window and the flushing starts again

i think i'm not being clear

Make a shitty park with no toilets in it just for the purpose of recording toilet-less park audio

then play in a real park and listen to the audio of your previously recorded toilet-less park
