Hi,
i would like to request a feature for the Desktop as well as the Mobile Apps:
I think it would be great to be able to upload a MP3-file as a Sirenesound.
If the uploaded MP3 is longer than 5 Seconds (i recon that's the max. time) the App will neglect the rest.
Recording a Sirene via Smartphone Mic is fun but that feature would lift the possibility to have an induvidual sirene to a whole new level 
Best,
Ron
