Atrium offers the perfect mix of a high-quality realistic-sounding reverb, easy usability and maximum customisability. Atrium also offers advanced features such as cross-instance synchronisation and more.

Most importantly: Atrium provides a holistic solution to reverberation, stereo positioning and stereo width, as well as depth perception. No combination of panning, stereo positioning tools and conventional reverbs create such a convincing stereo field, room impression, and depth perception as Atrium.

Atrium’s Room Creation and Positioning workflow.

Creating your custom acoustic space is easy:
Drag the room to your desired size, position the audio source and listener, and enjoy the result that accounts for the stereo positioning information and stereo width, as well as depth information.
Use the advanced controls to sculp the sound further and make it uniquely yours, or try some of the supplied presets.

Thanks to Atrium’s Synchronisation feature, it is incredibly easy to place multiple instruments or other sound sources into the same room. Use it to quickly and intuitively create a realistic and holistic room impression, including the sense of both direction and depth for each individual instrument. It’s a big time-saver for more complicated setups and gives you a great overview at all times.

Atrium’s Synchronisation feature makes it easy to keep track of instruments at various positions. Showcasing the “Light” theme.

Simply add an instance of Atrium to each sound source that you want to place into your room and click the Synchronisation button. Enable Sync. from here in the instance you want to work from, and the room configuration will be synchronised across all Synchronisation -enabled instances.

Here is what some of our customers think about Atrium:

Great plugin! I’m loving how realistic the space it creates is. I have not heard anything like it and I have tried many different reverb plugins. What’s most noticeable is how well the space combines with the original signal—this must be a post-production mixer’s dream come true.” – majoraxis on Gearspace

Must say that I’m impressed, to say the least. It worked as expected in Logic and the fact that you can see what’s happening with all instances is deeply appreciated. Congrats for what you’ve achieved with this software, this is amazing!” – Yan
