I’m a music producer and sound designer (a little bit a Blender artist as well) and along with other projects I’m creating a library to help game creators with specific sounds. Every sound in this library is designed by me and right now most of content are Sci-Fi | Mechanical | Ambient oriented. Sounds are seamlessly looped, OGG Vorbis format.
So, check it out, listen to previews and download sounds you need!
Sound Blend: 400+ sounds so far.
