apulSoft – apVerb v1.2.4 VST, VST3, AAX for Windows

• Velvet-Noise Acoustic Core: Generates diffuse reverberation using thousands of semi-randomly spaced delay taps, eliminating metallic ringing, modal buildup, and comb filtering found in classic delay networks.
• 23 Spline-Based Envelopes: Multi-segment curves with adjustable point weights govern volume, diffusion density, filter sweeps, modulation depth, and stereo width across the reverb decay.
• Topographic Spectrogram Visualizer: Continuous real-time 2D/3D frequency response visualization inspired by elevation contours on topographic maps.
• Host Tempo-Synchronized Envelopes: Lock pre-delay times and spline envelope stages to DAW BPM subdivisions for tempo-matched swells, gated tails, and rhythmic bounces.
• Geometric Early Reflection Generator: 3 selectable room simulation models reproducing early boundary wall reflections based on virtual room dimensions.
• Transient-Aware Dynamics Stage: Onboard ducking to suppress wet signal against dry vocal/instrument peaks, plus instant reverb tail resets on incoming transients to prevent mix mud.
• Time/Frequency-Targeted FX: Modulate specific temporal or spectral regions with integrated Chorus, Phase Distortion, and Saturation stages.

Reverb Core & Density Shaping:

• Replaces traditional feedback delay networks (FDNs) with a dense array of velvet-noise delay lines to create an ultra-smooth, flutter-free acoustic body.
• Reversible Density Flow: Envelopes can thin out or cluster delay reflections over time, creating unconventional backward reverbs, expanding frequency contours, and evolving ambient washes.

The 23 Spline Envelopes:

• Adjust individual control points with tension/weight handles.
• Simultaneously automate Reverb Level, Density, Low-Pass / High-Pass Cutoffs, Resonance, Parametric EQ bands, Chorus Depth, Phase Warp, Saturation Drive, and Stereo Spread across the time domain.

1. Frequency Section:

   • High-Pass and Low-Pass filters with continuously variable pole slopes.
   • Dual parametric peak/notch EQ bands.
   • All filter cutoff and gain parameters can be linked directly to dedicated decay envelopes.

2. Modulation & Distortion Suite:

   • Chorus: Smooth multi-voice pitch detuning for tail widening.
   • Phase Distortion: Modulates reflection timing to smear transients.
   • Saturation: Adds soft analog clipping and harmonic warmth to chosen decay zones.

3. Dynamics & Ducking:

   • Envelope-follower ducking to push the wet tail behind active signals and bloom in pauses.
   • Automatic transient threshold reset that instantly flushes the delay buffer when a new drum hit or vocal syllable arrives.

4. Workflow & Utilities:

   • Independent Dry lock button to switch presets without altering dry/wet blend balances.
   • Unlimited Undo / Redo history tree for all editing actions.
   • Cross-platform XML preset architecture for simple sharing between Windows and macOS.
   • High-contrast Light, Dark, and customizable user UI color themes.

• Binary Architecture: Native 64-bit Windows DLL / VST3 / AAX
• Audio Engine: 64-bit internal floating-point processing
• Sample Rate Support: 44.1 kHz up to 192 kHz
• Compatible DAWs: Ableton Live, Image-Line FL Studio, Steinberg Cubase / Nuendo, PreSonus Studio One, Cockos REAPER, Bitwig Studio, Avid Pro Tools
