What is a seamless audio loop?
Music or ambience cut so the end flows straight back into the start with no click, gap or jump in rhythm.
Musical loops are cut on an exact number of bars so the beat lines up when the file repeats. Keep loops as WAV or Ogg Vorbis: MP3 encoders add a short silence at the start and end, which turns into an audible gap every time the loop restarts.
Turn on looping in the engine's import settings (in Godot, the loop option on the imported audio) rather than restarting the sound from code, which can add a frame of delay.
