 Yes, I will attach it here. I produced it using the command
 ffmpeg -i in.mp4 in.wav

 This wav file sounds ok.

 Then I convert it to aac using
 ffmpeg -i in.wav out.aac

 and it sounds stuttery again.

 > ffmpeg -i in.mp4 -acodec libfdk_aac out.mp4

 This one sounds ok! Can I use libfdk_aac as a drop-in replacement wherever
 I would have used aac?
