Act in real time
A series of ultra-responsive dynamic EQs reacts when a frequency starts to ring. The action stays local and temporary, so the rest of the signal can remain as natural as possible.

Goodbye feedback. Keep the music.
Larsen Lupin uses ultra-responsive, real-time dynamic EQs to calm the frequencies that begin to ring. It acts precisely where feedback appears, then releases again to preserve the life of the sound.
Optional purchase · permanent €49 licence · separate from the StageFlow bundle.

WHAT IT DOES
A series of ultra-responsive dynamic EQs reacts when a frequency starts to ring. The action stays local and temporary, so the rest of the signal can remain as natural as possible.
The aim is not to flatten the sound, but to calm the troublesome frequency when it appears. Intensity, profiles and extra processing help you adjust the behaviour by ear.
Sources, microphones, loudspeakers, rooms and required level all matter. It cannot promise perfection everywhere, but the result can be striking in the right conditions. Start low and compare with bypass before live use.
INTERFACE OVERVIEW


FREE USE · OPTIONAL SUPPORT
Larsen Lupin is fully available to try for 30 days. An initial free online activation is required before audio can start; it is not a purchase. Afterwards, the saved activation supports offline use. All audio features remain available without buying a licence. After the trial period, a light startup reminder appears without interrupting an ongoing audio session. The optional permanent €49 licence removes this reminder and supports development.
Version 2027.3
Windows 2027.3: standalone app and VST3. Targeted REAPER editor, synchronisation and project-reopening checks completed. Unsigned installer; physical listening has not been performed.
Mac 2027.3 universal: standalone app, AU and VST3. Tested on Apple Silicon; Intel hardware validation has not been performed. Not notarised by Apple.
Windows 2027.3: standalone application and x64 VST3. Personal upgrade from 2027.2 verified: ten exact delivered files, 25 identical personal files and preserved log prefix, with application startup and normal closure observed. Eight offline VST3 cases on a stereo fixture at 48 kHz / 256 samples checked Auto and bypass outputs bit-identical to 2027.2 on that fixture, observable processing, finite values and parameter restoration. In REAPER 7.79, the exact module, editor, bidirectional Amount synchronisation and preservation of the amount and an On / 750 Hz / −6 dB / Q32 notch after saving and reopening the project were observed. Transport used a synthetic signal with Dummy Audio at 44.1 kHz / 1,024 samples. No physical listening, final −6 dB attenuation measurement, ASIO 64/128-sample validation, long-session or all-signal equivalence is claimed. The 31 historical IndependentEngine failures and four mode failures remain unqualified. Unsigned Windows installer. The Windows 2027.3 manual below replaces the Windows 2027.2 reference in the historical Mac notes.
Mac 2027.3: universal Apple Silicon / Intel standalone application, AU and VST3. The 11 selected CTests passed on ARM; Intel is checked statically. The 31 historical IndependentEngine failures and four mode failures remain unqualified. These checks do not establish general feedback suppression, Windows/Mac equivalence or validation in Logic, other hosts or on real hardware. macOS 11 is a minimum declared by the installer and inspected slices, without a runtime matrix. Ad hoc signing, without Developer ID or notarisation. The manual embedded in the DMG was verified and is available below as the Mac 2027.3 reference; the Windows guide retains its 2027.2 reference.
