I asked our Anomaly Sound Designer how our Anomaly SFX are crafted :
"
I start by using exotic animal sounds from libraries as a base. Then I post-process them by adjusting pitch, adding distortion, and applying spectral pitch shifting to make them sound more like a monster. After that, I build additional layers around the sound to make the SFX more unique and give it personality. I mainly use props layers for this, either recording them myself or taking them from libraries, and I aim for a good tonal balance to make the sound richer and fuller.
Sometimes, I use my own voice with different instances and layers, like a low distorted part, a medium/tonal part that’s heavily processed to sound screechy, and a high-frequency textured part. I also occasionally use synthesizer sounds that I craft myself to create some weird additional layers.
For recording, I use an external microphone (Zoom H5) for props and texture recordings, and a condenser microphone (Audio-Technica AT4040) for voice recordings.
