Louder sirens and ignore mute #1

Open gabor-boros opened 6 days ago

Although I don't know much about Android, on iOS, it is possible to send alerts that ignore if the device is muted. These alerts are extremely loud as well.

Would it be possible to increase the volume of the current sirens (like, by over amplifying it) and ignore if the device is muted?

Hey @gabor-boros! I think I know the alerts you're mentioning. They're usually sent by governments for natural disasters or similar.

Based on the research I just did, it's Wireless Emergency Alerts (WEA) via cellular networks, called Cell Broadcasting. It's OS level unfortunately.

However, in this case, we just need to raise the volume to the max so the siren is loud. On android, it's possible to do that, but adds complexity. On apple it requires a permission that's rarely accepted.

Those were some of the corners I cut to get this out there quicker. Now, I can try to implement them.

While promoting though, I learned that rescue teams use infrared to discover victims under rubble. That's much better and more reliable tech than what I'm trying to build. So I'm going to wait slightly longer to know whether it's useful to continue building this or not.
