You Have A Baby To Thank For One Of God Of War: Ragnarok’s Sound Effects


Alex Previty, a sound design lead who worked on God of War: Ragnarok, revealed that they used their baby’s heartbeat while still in the womb to create the eerie noises made when players visit The Spark of the World.

The news comes from X/Twitter, where one user uploaded a clip of them playing Ragnarok and explained how they love the noises made when they visit this area. Shortly after that tweet was published, Previty explained how the noise the studio used for The Spark of the World was their daughter’s heartbeat while she was still in the womb. And it was recorded using a “3.5mm output of a baby doppler.”

It’s also worth pointing out that the noise players hear isn’t just a baby’s heartbeat. As a matter of fact, in addition to hearing that, there’s also an edited kids’ choir playing on top. In that same tweet, they explain that “the longer tonal elements are from a children’s choir warming up in a gymnasium.”

In a follow-up tweet, Previty gave more insight into how the sound effect was made by sharing how the noises sounded before and after the effects were implemented. To help capture the right sound, Previty revealed they had slowed down the baby’s heartbeat to help get the pacing right and to make it sound larger.
