[QUOTE="Mark FX, post: 1615657, member: 211556"] I have not done anything with the AVAudioPlayer class myself for a while, but the problem is the fact that the your playSound: method is creating and initializing the AVAudioPlayer class, then loading the URL or Data from a sound file, then also preparing itself to be able to manipulate the sound file, so thatt's the reason for the lag time your experiencing. You should try to initialize and pepare the AVAudioPlayer well before you need it to play, perhaops in another method, after the user has selected a sound file in a list, or from a file open dialog box. That way the play button and corresponding play method is only having to tell the AVAdioPlayer to play only, and that should reduce the time lag a bit, but by how much migth take some experimentation.
