Impulse Anvil VST3 ZIP.

Current release

Fixed

• Fixed a DAW freeze that could occur when removing an Impulse Anvil instance after the plug-in editor had been opened.

Current package addition: Omni Path

Omni Path uses the selected Lerp Start and Lerp Time source window, but its output clock comes from the full 2-D route. Horizontal and vertical movement both consume time while X remains source-time and Y remains A/B or relationship depth.

• Vertical movement creates real duration.
• Lerp Start offsets the source region Omni reads.
• Lerp Time scales the source window and the route duration derived from it.
• Glue Path remains independent of Lerp Start/Time.

Impulse Anvil expands from A/B morphing into a much deeper impulse-response construction workstation.

21 Morph relationships

• The full Morph library now contains 21 ways for A and B to interact.
• New Residual / Decompose relationships can reveal what two responses share, what belongs mainly to A or B, and where they differ.
• New Acoustic Interaction relationships add Nest, Transfer, Ghost, Eclipse and Spectral Time Shear for more unusual structural transformations.

Glue Path

• Draw separate pieces from anywhere in source-time and join them into one new sequential IR.
• Move forward or backward through the source inside each stroke.
• The route itself determines the constructed timing, independently of normal Lerp timing.

Focus View

• Expand A, Morph, B, EQ, Edit or Out into a larger workspace when one part needs more precision.
• Return to Overview without changing the underlying sound or state.

New browsers & safer exploration

• The IR Browser adds search, waveform/stats inspection and Compare before loading a candidate into A or B.
• The Morph Browser organizes the larger mode library and explains what each relationship is for.
• Global Undo / Redo lets you explore IR loads, Morph changes and Draw / Path / Glue edits without losing a good state.

DESIGN workspace

• A persistent DESIGN workflow now handles theme browsing, importing, editing and saving.
• Liquid Slate is the new default visual design.

Expanded the curve system from preset shapes into direct IR authoring.

• Added Draw curves with Undo, Smooth, Precision Nodes, Free endpoints and Reset.
• Added Path routing through source-time, including real backward travel that can revisit earlier IR samples.
• Lerp Start and Lerp Time moved to direct millisecond timing and follow the available prepared IR duration.
• A/B waveforms became visible behind the curve for source-length and landmark guidance.
• Fade In now supports a true authored 0 ms path for micro-IR work.
• Color Offset expanded to 500 ms.
• Theme Schema 2 added optional per-panel styling while preserving Schema 1 compatibility.
• Improved IR browsing defaults, dialogs and control tooltips.
• Draw/Path Preview and Bake share the prepared rendering path.

This maintenance release refreshed the Windows commercial build after migration to JUCE 8.0.13.

• Rebuilt the Windows 64-bit VST3 with JUCE 8.0.13.
• Refreshed the commercial release package and build process.
• Corrected the license activation dialog layout after the framework migration.

Existing projects and sessions remained compatible.

This update focuses on cleaner workflow, improved A/B slot handling, new spatial morph behavior, better loudness control, and a more coherent randomization/layout experience.

New Spatial Morph Modes

• Added Stereo Slot Swap, a spatial morph field where the left channel moves from Slot A to Slot B while the right channel moves from Slot B to Slot A.
• Added Mid/Side Boundary, keeping Slot A in the center/mid field while introducing Slot B into the side/outside field.
• Both new Morph Modes are supported in normal Morph preview, A-to-B Lerp preview, project restore, and Lerp Bake/export.

Improved Drag & Drop Slot Routing

• Dropping a WAV file onto the A panel now reliably loads Slot A.
• Dropping a WAV file onto the B panel now reliably loads Slot B.
• The empty-slot fallback behavior outside the A/B panels is preserved.

Loudness & Normalize Workflow Cleanup

• Slot A and Slot B now have their own Normalize controls.
• Old sessions that used the previous global Normalize setting remain compatible and migrate safely to the new A/B Normalize setup.
• Slot Gain remains useful when Normalize is enabled, making A/B compensation easier after normalization.
• Output/Post Normalize now defaults to ON, and the visible Post Limiter clearly controls final output limiting.
• Random, load, and reset workflows no longer unexpectedly reset Wet Level to -30 dB, except for factory startup defaults.

Randomization Workflow Improvements

• A/B full-slot random buttons randomize the full slot IR selection and related full-slot behavior.
• A/B Color-header random buttons randomize the current IR's Color controls only, keeping the loaded IR in place.
• Morph Random is available directly in the Morph card and randomizes Morph-related controls only.
• EQ and EDIT now have their own local random buttons.
• A/B Random resets Slot Gain to 0 dB and no longer randomizes gain above unity.

Layout & Usability Polish

• Init/Reset Controls has been moved into the Options menu.
• Clicking the A, B, or Morph panel background now selects that mode.
• Moving a Color voice knob automatically enables that Color voice, so the change is immediately audible.
• Morph Mode and Curve dropdowns are now centered in the Morph panel.
• K and Lerp Time now use compact horizontal controls above the curve display.
• Align Peaks has been renamed to Align with a clearer tooltip.
• Post random tooltip now clarifies that it affects EQ, EDIT, and OUT.

Fixes

• Fixed A/B WAV drag-and-drop target detection.
• Fixed EDIT double-click reset behavior when linked Start/End or reverse Fade Out are active.
• Fixed Morph Random build handling from the previous internal build step.

Existing projects and sessions remain compatible.

Small maintenance update for Texture Depth.

• Fixed a "Texture" bug, previously introducing the wrong IR when tweaking parameters.

This update makes prepared IR length handling more predictable across preview, editing, statistics and baking.

• Preserves quiet reverb tails that belong to the loaded or processed IR instead of trimming them unexpectedly.
• Uses the same prepared-IR length policy for convolver preview, A/B slot stats, Bake and A→B Lerp export.
• Keeps a hard 30-second safety cap for generated Color, Texture, Morph and Lerp results.
• Prevents mismatches between long Color/Texture stats, shorter Edit ranges and convolver safety kernels.
• Color, Texture, Morph, Lerp, project restore, Normalize and Limiter behavior are unchanged.

• Improved C1/C2 Color switch rendering so the labels stay readable in tight rows.
• A/B prepared IR stats are now laid out directly in the active manual A/B panels.
• Improved Lerp curve display readability in the default theme.
• Theme randomizer tooltip now shows the current theme name.
• Normalize tooltips now warn clearly that quiet IRs can become much louder.
• A/B/Morph switching now uses a safer unity-sum crossfade to reduce brief correlated level boosts.
• Spectral, BandSwap and ZigZag Lerp snapshots are normalized when Normalize is enabled, reducing weak or silent middle sections.

• Added per-slot prepared IR stats for A and B: Peak, RMS and IR length.
• Slot stats follow the prepared slot after Time, Gain, Color, Texture Depth and Normalize.
• Color voice switches now draw as compact C1/C2 controls instead of being shortened to ellipses.
• The factory Anvil Blue theme was slightly calmed for a cleaner first-run look.
• Stats update from the editor side with throttling; no audio-thread work was added.

• Color enable switches now display C1 and C2 visibly.
• Added clearer C1/C2 tooltips for A and B Color voices.
• No DSP, Morph/Lerp, Color/Texture, backend or licensing behavior changed.

• Added safer cancellation for heavy Morph/Lerp preview jobs.
• Closing the editor, deleting the plugin, closing a project or quitting the DAW can now cancel pending Morph/Lerp work cleanly.
• Background preview, convolver and Color jobs now check shutdown state before publishing results.
• Added a subtle masthead build glow while heavy Morph/Lerp preview work is running.
• The old IR keeps playing until the new preview IR is ready.

• A→B Lerp Preview now uses the selected Morph Mode.
• Time Morph Lerp remains the default compatibility path.
• Spectral, BandSwap and ZigZag Lerp are built from fixed intermediate snapshots for more mode-specific movement.
• Preview, DAW project restore and Lerp export now share the same processor-side Lerp build path.
• The unified Bake button still exports the prepared IR exactly as heard.

• DAW project save/load restore now rebuilds the active internal preview IR from the processor side.
• Saved A/B IR paths and A Only, B Only, Morph and Lerp state are restored without requiring the plugin editor window to be opened.
• Morph restore supports Time, Spectral, BandSwap and ZigZag modes.
• Baked/prepared IR audio is not stored inside the DAW project; the plugin rebuilds it from saved state.

• Morph Mode, Align Peaks, Curve Type and Curve K now persist through the plugin state.
• Closing and reopening the plugin editor no longer resets these controls to default values.
• Texture Depth recursion is safer when only one Color voice is enabled.
• Texture Depth and IR Gain tooltips were clarified.

• Prevents stale preview jobs from overwriting the currently processed IR.
• Morph Mode changes now rebuild more deterministically, especially for spectral modes.
• Strengthened preview identity handling so different spectral results are less likely to be treated as identical.
• Align Peaks now only rebuilds Morph/Lerp preview and no longer reshapes A Only or B Only.

• When Normalize is enabled, processed A and B endpoints are balanced before normal Morph interpolation.
• This prevents a very loud Color/Texture endpoint from dominating almost the entire morph range.
• Spectral, BandSwap and ZigZag modes now keep more of their direct spectral character in the middle of the Morph knob.
• Morph endpoints remain exact: 0.0 is processed A and 1.0 is processed B.

• Texture Depth is now the single audible source of truth: 0 is off, 1–4 are active recursive depths.
• Hidden legacy parameters remain only for old-session compatibility.
• Preview and convolver rebuild paths now agree when Texture Depth changes.
• Fixes cases where the plugin could flip between a processed Texture/Color IR and an older/basic IR while dragging or pausing controls.

• Texture Depth was simplified into one 0–4 control.
• Dry/Wet became the main dry routing control and defaults to 100% wet.
• Added A/B swap for loaded IRs and slot-specific creative controls.
• Preview buttons were clarified as A Only, Morph and B Only.
• Post Random gained more useful edit slicing, including tiny, medium, long, forward and reversed regions.

• Improved dry-path transparency and limiter-off behavior for normal floating-point audio.
• First-run factory loading can initialize A/B even when only one valid factory/user IR is found.
• Removed disruptive modal popups for normal A/B selection cases and replaced them with inline guidance.
• Drag-and-drop loading now targets A or B based on where the file is dropped.
• File loading accepts WAV, AIFF and FLAC through JUCE basic formats.
• Texture Depth and IR Gain remain editable in more normal workflow states, with tooltips explaining the behavior.

• Edit Start, End and Fade ranges now follow the prepared IR length published by the processor.
• The Edit range tracks Color, Texture Depth, Morph and stretch length changes without collapsing when Start/End trim the final IR.
• Shift and Ctrl precision handling is more stable during slider and knob drags.
• Width behavior remains unchanged: 0.0 narrows toward mono, 1.0 keeps the original stereo width and 2.0 expands side information.
