Male or female? Video of quack

[debrasage]

Here is a video of our Pekin duck - is it male or female? At first I thought male but the noise is not raspy like I've read but I'm still thinking male (Excuse the gloves, we need to clean their hay out and didn't want poop on me in my work clothes )

Male. I have a female and she has a very loud distinct quack. My male khaki sounds like yours
