Hello, I'm working on a top down GTA 1/2 type game where you can steal cars and get into police chases and the like, but right now I'm using engine and siren sound effects from the GTA V game files. I'd rather use/find my own sounds, but every royalty free siren sound on the internet sounds like garbage or is too simple to sound like a real police siren. Also where should I get car engine sounds? I can just record the sound of a car idling, but there will be background noise outside/ echo if I decide to do it in my garage. I can use an 8-bit sound generator, that would fit well with the low pixel density sprite art style of the game, but I don't know how to make a car sound. I also want to release a demo in the Work in Progress forum but I'm just stealing sounds from GTA V which looks lazy, and could cause trouble if I decide to sell or release the game for free(?).
