Slow start for AVAudioPlayer the first time a sound is played

Question

I\'m trying to eliminate startup lag when playing a (very short -- less than 2 seconds) audio file via AVAudioPlayer on the iPhone.

First, the code:

Answer 1

Other workaround is to create a short & silent audio and play it on the first time player is initiated.

1. Set the microphone level to 0 on System Preferences.
2. Open QuickTime.
3. Create new Audio Recording (File > New Audio Recording).
4. Record for 1 or 2 second.
5. Save / Export the audio file. (it will have .m4a extension and about 2 kb on size).
6. Add the file to your project and play it.

If you dont want to create a new sound file yourself, you may download a short & silent audio file here : https://www.dropbox.com/s/3u45x9v72ic70tk/silent.m4a?dl=0
