Some time ago I decided to write my own soundboard since I wasn't satisfied with existing solutions. And here it is: a simple yet powerful soundboard that requires NO COMPLICATED SETUP! Just install and it's ready to use. No extra tools, no fiddling with push-to-talk settings etc. It comes with a set of predefined sounds but of course you can choose your own.
Only Windows is supported at this moment.
