In WhatsApp you can set custom notification sounds, I believe it even supports notification sounds on a per-contact basis. So safe to say you can do it as an app developer.
I used to use custom sounds I downloaded for a few people and it was useful, but it’s clunky and time-consuming to set up for even a few contacts. I had to get the sounds on a PC because all the sound apps on the store feel like malware and are riddled with ads.
