Eigen is a reverb plugin that lets you recreate the profile of a room by selecting dimensions. Choose exactly where the source and listener are placed, and experiment with combinations of materials on each of your six walls to simulate architectural acoustics.
Eigen can also export an impulse response file of your room, and can be useful in analyzing the room modes and resonances at play in your virtual space.
Dimensions and Materials
The Room sliders let you set the room’s dimensions for width, length and height. The cuboid display above will adapt to show you the shape you’re creating.
You can choose the Wall Material for the six surfaces, from a range of wood, concrete, brick and curtain options, to make acoustic reflections behave differently throughout the space.
For musical reverb, you can create spaces from a small vocal booth through a wooden drum room to a stone cathedral. For sound design, you can simulate a concrete corridor, a tall staircase or a brick warehouse.
Source, Listener and Spatial Mode
Select exactly where the sound source and the listener are placed within your space using X, Y and Z co-ordinate sliders, just like the wall dimension selectors.
Choose whether the virtual reverb signal is behaving in Mono, Stereo or Binaural, depending on whether you have a stereo source and how you want the reverb to come across.
Render Impulse Responses
In the Render tab, you can export your space for use in a convolution processor, excellent for sound design or video applications, switching to another program, or simply keeping great-sounding spaces for later use. (Eigen also saves presets normally like any other plugin).
Analyze your Space
Part of a room’s ‘sound’ and character is caused by the build-up of frequency resonances, caused by the physical dimensions of the room itself – literally the distances between the walls. In Eigen, you can instantly analyze how your chosen dimensions and materials combine into a unique sonic signature, thanks to the low-frequency analyzer.

Beautiful software, bought today! Are you planning to add new materials like marble, glass, metal sheet coatings, walls covered with plants? I would also suggest to show a checkmark beside the selected preset and to allow the user to save his own presets within Eigen. Besides, I have experienced occasional UI problems (cubes representing Listener and Source were drawn outside the room and refused to follow the cursors movements) (Mac 12 Monterey, Logic 10.7.7, large Retina display).
Thanks for the comment! We’ll check out those UI bugs. As for presets, Eigen’s control scheme is relatively straightforward with only about 16 parameters so we decided to keep it simple and leave out a preset management system. The parameters can work natively with your DAW generally, and most DAWs have built-in plugin preset management support.
