推荐答案

没有内置的 iOS API 可以进行独立的时间音调修改.

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

Audacity 中有实现时间间距拉伸的开源代码，但我不知道是否此代码已移植到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.

有一个关于 DSP 维度的 Time-Pitch Stretch Tutorial网站.

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

更新:在 2012 年末，kAudioUnitSubType_NewTimePitch 音频单元包含并内置到 iOS 6 的版本中，因此您现在可以使用 iOS API 实现(独立的时间音调修改)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.
