推荐答案

没有内置的iOS API可以进行独立的时间间隔修改。

There are no built-in iOS APIs that will do independent time-pitch modification.

有一个开源代码可以在 Audacity ，但我不知道这段代码是否已移植到iOS。与 SoundTouch 相同。

There is open source code that implements time-pitch stretching in Audacity, but I don't know whether this code has been ported to iOS. Same with SoundTouch.

有一个在DSP Dimensions网站上 ime-Pitch Stretch Tutorial 。

There is a Time-Pitch Stretch Tutorial on the DSP Dimensions site.

更新：2012年末，kAudioUnitSubType_NewTimePitch音频单元包含在iOS 6版本中并内置，因此您现在可以使用iOS API实现（独立的时间间距修改）语音更改。有关详细信息，请参阅Apple的开发人员文档。

Update: In late 2012, the kAudioUnitSubType_NewTimePitch Audio Unit was included with and built into the release of iOS 6, so you can now implement (independant time-pitch modification) voice changing using iOS APIs. See Apple's developer documentation for details.
