Question

I am using multiple instances of AVAudioPlayer to play multiple sound files in a succession.

I am noticing that there is a roughly one second pause when two different sound files are played. Is it possible to eliminate this one second pause? I call [myPlayer prepareToPlay] for each player ahead of time already.

According to AVAudioPlayer documentation you could use playAtTime: for synchronized playing.

Modified example would look like this:

- (void) startSynchronizedPlayback {

    NSTimeInterval shortStartDelay = 0.01;            // seconds
    NSTimeInterval now = player.deviceCurrentTime;

    [player       playAtTime: now + shortStartDelay];
    [secondPlayer playAtTime: now + shortStartDelay + player.duration];
}

I didn’t test this but guess it should work. You should of course rename player and secondPlayer according to you names.
