Leading the pack

Cavern is the first 3D audio processor for the PC, redefining calibration and visualization, while being free and open.


Boundaries erased

Content made for Cavern adapts to any sound system you have in any environment. Cavern even supports in-floor speakers, thus creating great quality height representation and environment simulation. Unlike others, Cavern is completely free for anyone, no additional equipment is needed, and has no software limitations on speaker and object count.

High-end audio calibration

With minimal setup, Cavern's automatic calibrator, QuickEQ, sets up any standard calibration in even under a second per channel. With advanced features and the sheer power of a PC, the audio quality resulting from using most automatic calibrators, including actual cinema processors, can easily be surpassed, even with a single microphone.

Built for real-time

Everything Cavern does is designed to provide the lowest possible latency, which means a single sample. All features can be provided in real-time, with the only latency present is the environment you build on. Cavern is easily able to live in harmony with actual cinema hardware and provide spatial audio for content that wasn't even created that way.

Beyond adaptation

The development goal for Cavern is simple: make it the ultimate all-in-one audio processor. This goal led to the creation of theatre and stage listener adaptation, an automatic volume and panning recalibration based on occupied seats in real-time. What used to be only possible with extremely expensive acoustic room treatment, Cavern can do it in software.

A long way ahead

There is always room to expand Cavern's capabilities. One such experiment is Cavern4D, which generates seat movement automatically for your content, only by listening to audio cues. Headphone virtualization is also available.

Help the development of Cavern

Cavern is free and open source, even for commercial use, and always will be. Thanks to generous donations, this project is still afloat. If you really like Cavern and are satisfied with the results it provides, you can make a small donation by clicking the button below.
