用AVPlayer播放音频，当用setSpeed(0.5)设置速度时，速度是慢下来了，便声音变调了，请问下要怎么设置才能速度变慢，声调不变，请指教下，谢谢。 ## --- Want to back this issue? **[Post a bounty on it!](https://www.bountysource.com/issues/10617156-0-5-1?utm_campaign=plugin&utm_content=tracker%2F307703&utm_medium=issues&utm_source=github)** We accept bounties via [Bountysource](https://www.bountysource.com/?utm_campaign=plugin&utm_content=tracker%2F307703&utm_medium=issues&utm_source=github).
