For creature dialogue in a game or sound layers in a short film, Free Sound Design Kit combines the Dehumaniser Simple Monsters voice processor with the Krotos Starter Library of WAV effects.
Simple Monsters transforms incoming voices with five dynamic parameters and assignable X/Y pads. Its 35 presets provide starting points for creature dialogue, science-fiction voices and growls, while the Scrubbing Convolution module adds another way to combine material with the voice.
The Starter Library contains 3,956 royalty-free effects in 96/192kHz WAV format. Edit and layer these files separately from the vocal-processing plugin, building a scene from recorded material as well as performed character voices.
Register by email and complete checkout through the link you receive. The library download appears in your Krotos account, while the Simple Monsters licence is delivered to your iLok account. Have your iLok User ID or account email ready. Registration also adds you to the mailing list; unsubscribing later does not remove the products.
