`cannot execute binary file: Exec format error` on Ubuntu 20.04 and 22.04

Same here on Debian 12, x64

Edit:

  file FFMPEG-UI.AppImage 
  FFMPEG-UI.AppImage: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0, BuildID[sha1]=4b12022a0a60af0d4b7920deac219fcbd1d92080, stripped

It was compiled for 64 bit ARM...

Windows build was also compiled for arm64.

It should work fine now I rebuilt it to work for the x64 architecture.

If you want to filter out the rotor noise alone, switching to a directional microphone would be the best option IMO.
