Here’s a quick demo, via retronyms, of using AudioCopy on iOS 7:
In order to keep some of the best features of AudioCopy in iOS 7, we added a free standalone app. This acts as a “sound pasteboard” and seamlessly serves all the copied content to 3rd party apps. The AudioCopy app sits in the background and quietly serves the sound content to apps as they request it. If you don’t have the AudioCopy app installed, AudioCopy/AudioPaste still work using the general pasteboard.
AudioCopy is a free download from the App Store.
