Hi @max
Really good idea !
I got through this king of thoughts for my app and it was a real pain to find sounds (and even now, I’m not quite satisfied 
).
So, to me, it would be a really great (and unique for a web/mobile project I think) help if you added a sound package.
An other thing is how to play sound on hybrid app. I got through this and I ended with a lot of permissions (http://forum.ionicframework.com/t/how-to-play-local-audio-files/7479/8) only for some tiny sound… It would be great if you could improve media plugin to be more modular (in many cases, recording sound is not necessary I think).
I hope it will come soon.
Keep up your really great work
