Introducing Endurance SFX, a library of rhythmic underscore elements that blur the lines between sound design and soundtrack.

Our first two sound effect libraries — Archetype and Anticipation — provide the essential sounds for creating impactful moments in your films.

Endurance SFX is the driving force in between those impactful moments.

Underscores are sequences of sound that tie a film together. Your viewer is less likely to notice an underscore, but they’ll feel something is missing if it isn’t there. You might use an underscore as an alternative to music, as a light presence, or as a driving force to push your story forward.

Endurance SFX is all about this third use. The library’s percussive elements, pulsing drones, abstract patterns, and organic textures were captured with the idea of drive and determination in mind.

Use these tracks to create an underlying sense of progress in scenes where your character is rolling up their sleeves, preparing for the big day, or resolved to reach a breakthrough.

The tracks in Endurance SFX are designed to be layered together in endless combinations. They are more singular than music loops, but more systematic than individual sound effects.

Most of the tracks are between 30-90 seconds in length, allowing you to create underscores for an individual scene or an entire project.

There is a wide variety of patterns across the clips, but they all share a common tempo (90 BPM). This gives you the freedom to experiment, mix-and-match, and create unique soundscapes for your commercial projects or cinematic short films.
