There are certain algorithms like the Griffin Lim algorithm or Single Pass spectrogram inversion that do a phase retrieval pretty well. But that is not my intention at all. My end result just has to be within the bounds. That's very critical | |

| Apr 9, 2019 at 16:45 | comment | added | user35593 | This problem is called phase retrieval. en.m.wikipedia.org/wiki/Phase_retrieval however i dont know if the min and max constraints can be handled. You can only expect to find the solution up to a translation as a translation is equivalent to a change in phase in the Fourier domain. | |
