when I play the audio in after effects it does this little glitch sound almost like when ur headphones do a weird popping noise if you pull in the chord too hard while listening to music. I thought maybe it was just playback, but after it rendered, it still had those little crackling noises and small pops in it. I then thought maybe it was my heaphones, so I used a new audio with no headphones on and it still did the glitch. I then tried wireless heaphones, still a glitch. I am not sure if it is the process of airdropping the audio from my phone to my computer, but I have never had this issue before
Without any actual info about your computer, your project contents, render and preview settings, audio preferences and so on this is not going anywhere I'm afraid. The issue could simply be a genuine glitch in the source file itself or resampling artifacts from converting sample rates and of course outside that there's a million other potential things. You simply need to be much more specific.
