推荐答案

解决方案:我试过 SoundTouch 库.我为 android 编译成功但后来我没有使用它的功能，因为我不知道如何使用这个库来加载音频.

Solution : I tried SoundTouch library. I compiled it successfully for android but then I failed to use its function because I don't know how to use this library to load audio.

但在那之后我尝试了名为 Sonic 的库.它基本上用于语音，因为它使用 PSOLA 算法来改变音高和速度.不过没关系.

But after that I tried library called Sonic. Its basically for Speech as it use PSOLA algo to change pitch and tempo. But its ok.
