An algorithmic room reverb plugin, using a Feedback Delay Network of all-pass filters with adjustable frequency-dependent absorbency.
Realistic and experimental reverberation time curves are synthesised from an input signal via a tapped delay line and unitary Hadamad matrix of recursive series all-pass filters.
The amplitude and delay of early & late reflections may be adjusted independently, thanks to energy compensated gain staging throughout the signal path.
Includes 14 example presets, based on I3DL2 standard, for fast assessment of possibile effects.
Written in C++ using the ASPiK framework (http://www.aspikplugins.com/), controlled via custom vector-based GUI created in Adobe Illustrator & Figma.
