摘要
介绍一种基于调制和延迟线的语音变调算法,并讨论了对该算法的实时改进以及在DSP平台上软件实现的问题。结果表明,基本感觉不到语音延迟,也未有相位不连读声。
A pitch shifting algorithm based on modulation and delay line is introduced. It's importance in real-time processing and realization on DSP is also discussed. Results show that the delay of the sound is almost imperceptible and there is also no phase discontinuity.
