| Jul 31, 2018 at 7:34 | comment | added | Arunima Pathania | I am new to this and was looking around to use filtfilt. @endolith said that the scipy.signal uses the original signal. I am not sure what the original signal means and how we get it. I have a wav file that I load onto my system but I do not think it is the original signal since it is broken up into a numpy array and number of samples. Please if someone could help. Thank you! | |

@Aaron filtfilt does the same filter twice, in opposite directions, so it's not any slower than doing lfilter twice in one direction, which is how you would get the same frequency response.
