<div>Hi all,</div>
<div>Thank you for your reply <span style="background-color: rgba(255, 255, 255, 0);">
Yamil. </span></div>
<div>How do I get the GUI to not use a reverse filter? I am only using the GUI to get an automatic setting for the filter length/order. If I now swapped the location of the 1, and set the reverse to false should the filter order change? </div>
<div>Do I have to repeat the filtering I've already done? Or is it equivalent?</div>
<div>Thank you and best wishes,</div>
<div>Jumana <br>

<p dir="ltr">Hi, <br>
Is because the 5th parameter (revfilt) is set to true, which indeed reverses the direction of the filter, turning the lowpass into a hipass.<br>
I was also confused the first time. <br>
Cheers, <br>
Yamil</p>
