What sort of sci-fi spaceship sounds can you create without using jet plane recordings? Here are a few options!

This library brings you 840 meta-tagged sounds recorded and created at 96kHz/24-bit stereo that can be used to bring your spaceships to life. This includes 376 designed sounds with various flybys, lift-offs, and landings for large, medium and small spaceships, as well as the 464 ingredient sounds that were used to create them, allowing you to customize and tailor the sounds to fit your project precisely.

Note: The sounds in the audio example have some panning and reverberation added; the sounds in the library itself are centered and entirely devoid of reverb.
