Re: How to minimize delay when playing an audio clip
Another trick that I’ve used in the past (when using players; I’ve haven’t used imported audio clips much) is to play a very short, silent audio file at some point in a preOpenCard or openCard handler. This kind of gets the audio ball rolling so to speak, then when I need to play my actual audio, there is no delay. Whatever needs to load in the background in order for audio playback has already loaded. A bit of a hack I suppose, but it works. :-) Chris -- Chris Sheffield Read Naturally, Inc. www.readnaturally.com On Aug 15, 2015, at 11:52 AM, Mike Bonner bonnm...@gmail.com wrote: I have an audio clip that I'm using as a sound effect.

Thanks for the suggestion, 2 things on the list to try now.

In any event, I've never done this, but you might try using an imported video clip with no video track (if that's possible) so it contains your audio only, and use the prepare command, which supposedly allows the imported media to start playing immediately. If you can't make a video-less movie, another option could be to make the video 1 x 1 pixel in size. Even if a videoClip somehow employs a player for playback, the prepare command might reduce the start lag.

Re: How to minimize delay when playing an audio clip
great idea, thanks. I've clipped the file down to just what I need so its pretty tiny. I'll give it a shot!
