the phase problem about 1777_dsp
How can I implement the function about phase addition, phase subtraction, and phase invertion in the studio about 1777_dsp. Or are there any modules relevent to such functions in the studio? If you can give me some examples, its much better !
Thanks a lot ,with best regards !
Hello sunshihong,
I just answered your other post with the same question but in this post you supplied the correct name of the DSP.
Here I your other post:

The ADAU1777 is a totally different type of processor. It is more of a filter engine rather than a general purpose DSP.
So it is little more difficult.
My first thoughts is to use the General 2nd Order filters and use the IIR Coefficient filter settings. Then you can use your own coefficients to do the phase inversion. That will be easy to do but I am not certain exactly how to make an IIR filter only change the phase. However, I am not a filter expert so others on the forum might be able to help.
