| Aug 24, 2017 at 22:34 | comment | added | endolith | I mean zoom in on your plot after filtering | |
| Aug 24, 2017 at 20:49 | comment | added | CJF | When I zoom in on where the glitches appear in the unfiltered signal, everything seems to be fine- There is no glitch. I tried the filter on an array of ones and It did not affect the output at all. I read in a 30 second wav file, split it into 5 second segments and applied the filter to each segment and everything worked perfectly so I think there may be something wrong with how I'm recording the audio. | |

Also what does it look like if your input is just ones(N)? A notch filter should leave DC alone and the output should just be ones, also.

| Aug 24, 2017 at 16:13 | comment | added | CJF | I altered my code to reflect this, shown in the edit to my question above. I still have the same problem of strange peaks occuring where they shouldn't although it seems to remove the peak that occurs at the beginning and the end of each chunk. | |
