Hello,
I am working on acoustic signal processing. I applied an AGC and a filter (with the filtfilt function) to my data set. As I still had a lot of noise I finally used the function medfilt2. Does it affect my phase? I mean... can I consider the medfilt as a zero-phase filter?
Thank you very much in advance!

medfilt2 is a median filter, which is a non-linear filter. So, no, it cannot be considered a zero-phase filter.
