The NEMUS project has introduced a free spatial reverb plugin developed in collaboration with Missing Ear and Physical Audio.
Bunkervik Reverb is based on acoustic measurements of the Bunkervik tunnel, a WWII-era air-raid shelter in Brescia, Italy, now used as an art and performance space.
Using a modal synthesis engine the plugin recreates the sound of the tunnel with a dynamic microphone position, allowing real-time walkthroughs of the space.
The microphone rotation can be varied along with the overal damping of the reverberation. Additional controls for the Aura allow creative tuning of the high-frequency modes.
Bunkervik Reverb features
- 0–30m position control that walks the listener down the length of the modeled tunnel.
- >Aura: a high-frequency mode-stretching control with adjustable cutoff, max frequency, and boost.
- Mic Rotation control for biasing the listener’s orientation relative to the source.
- Adjustable damping.
- Two-LFO modulation matrix with host sync and multiple waveform shapes.
- Gain, Bass, and Dry/Wet controls on the output stage with stereo level metering.
- Peset library curated by sound artist Matteo Gualeni.
The plugin is available as a free download in VST3, AU, and AAX formats for Windows and macOS.
