Hi,
at the moment i am struggeling a little bit with the corona sound. First i tried only the audio.* library which worked very well on iOS but on Android i have a unacceptable lag. So i read in the forum that i have to use the media.* library for Android. I tried it and there is no lag anymore. Because i want to use mp3 for my audio i wrote a little library which automatically uses the correct audio lib for the different OS. If i use the lib everything seems to work very well. Because it is the first time i use sounds it would be very nice if you could confirm that my little lib is ok. All recommendations are welcome 
Of course isAndroid and isSimulator are set in the main.lua like:
myClass.isAndroid = “Android” == system.getInfo(“platformName”)
myClass.isSimulator = “simulator” == system.getInfo(“environment”)
Thanks,
Thomas
