AVAudioPlayer - 为什么会出现环路之间（uncom pressed音频）的间隙 [英] AVAudioPlayer - Why is there a gap between loops (uncompressed audio)

问题描述

NSString *path = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"caf"];
audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
[audioPlayer setNumberOfLoops:-1];
[audioPlayer setVolume: 0.1];
[audioPlayer play];

这是基本的code我有，让我知道，如果你需要了解更多。

This is the basic code I've got, let me know if you need to know more.

试用过COM pressed和uncom pressed两种格式有关于〜1秒的差距在iPhone模拟器上运行时（没有开发许可证的设备上运行测试）。

tried both compressed and uncompressed formats both have a gap of about ~1 second when running on iPhone simulator (don't have dev license to run on device to test).

我缺少的东西，我一直在寻找的职位，但我只能看到与COM pressed音频问题（这是有道理的）。

Am i missing something, I've been searching posts but i can only see issues with compressed audio (which makes sense).

推荐答案

你喜欢玩这之前尝试prepareToPlay

have you try a "prepareToPlay" before playing like this :

NSString *path = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"caf"];
audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL  fileURLWithPath:path] error:NULL];
[audioPlayer setNumberOfLoops:-1];
[audioPlayer setVolume: 0.1];
[audioPlayer prepareToPlay];
[audioPlayer play];
