Xcode audio problem with Webm


Hi, I have an app ready from Construct 3, everything is fine but I have audio problems only in Xcode. I exported the game from Construct 3 to Xcode using Cordova, but some high audio frequencies are distorting (aliasing). I think is a problem with WebM files. If I could add these audio files as m4a directly in Xcode, I think the problem would be solved. is this something that can be done?
Thank you in advance
