Godzilla Roar, Soundeffects Wiki

The Godzilla Roar is a vocal recording from movies. Godzilla's roar is a famous sound effect. Over the years, it has changed considerably, sounding different almost every time and having many variations for the different emotions. The sound effects team originally tried to create Godzilla's roar by using animal roars that had been edited. They sampled all kinds of birds and mammals, but nothing seemed to be the right match for the reptile-like noises a monster like Godzilla would make. Akira Ifu
