I’ve really enjoyed using Unknown Pass By by SoundMorph. What I like most about this library is the atmosphere and the unusual character of the sounds. They have a mysterious and sometimes slightly unsettling quality that works really well for cinematic sound design.
The sounds are very detailed and easy to integrate into my own projects. I’ve found them especially useful for creating tension, adding subtle background movement, and giving scenes a more immersive feeling. They also work well when layered with other sound effects and processed further.
For me, one of the biggest strengths is that the sounds don’t always have an obvious or predictable character. This makes the library fun to experiment with and allows me to use the sounds in ways that go beyond their original purpose.
Overall, Unknown Pass By is a very inspiring collection and one I can see myself coming back to regularly. It’s a great choice if you’re looking for unusual, atmospheric sounds that can add something special to your sound design.
Highly recommended!

Love them. It is a really unconventional pass by the library, which I am sure we will listen to them in the next movies very soon. Magical, electrical, space ships, comets, stars, new technology... All what I am not thinking about is probably there. Very interesting new king of pass by sound.
