请问ADAU1701  如何实现移频？ 比如输入1KHz 输出为992Hz

您好，请您参考英文数据手册
http://www.analog.com/media/en/technical-documentation/data-sheets/ADAU1701.pdf

数据手册没有这方面资料，还请帮忙解决，我们用来做防止啸叫的。

hi Allen,
It's hard for ADAU1701 to implement feedback compress and ADI doesn't have such kind of module for customers, neither.
You can have a try to use pitch shift if you have the algorithm.
Thanks!
Henry
