Outta This World Audio makes royalty-free sound effects for game developers. Every pack ships as uncompressed WAV at 44.1 kHz, 16-bit stereo, levelled to -1.5 dBTP so nothing clips when a game engine re-encodes it on import.

One licence covers commercial and non-commercial projects across unlimited titles, with no attribution required and no per-copy fee. The catalogue runs from themed packs of 20 to 30 sounds up to a 450-sound complete library, and 163 sounds are free under the same terms.

The packs are also sold on itch.io, Fab and the Unity Asset Store. This is the direct storefront.
