… and UI visualization - Derive tempo (BPM), volume, musical scale, and root note directly from SDF shapes. - Rebalance tones: sub/warm bass (40-85 Hz), mid-range chords/leads, and synthesized drum kit (kick, snare, hi-hat). - Anchor song visualization to the top-left UI corner with songPoint() and 10x UI scale. - Implement physics collision and friction audio with spatial panning and Doppler effect. - Update all sample scenes and add comprehensive documentation in docs/AUDIO.md.

- Add SystemParams::AUDIO_VOLUME (var11) and audioVolume() expression helper - Pass u_audioVolume uniform to 2D distance and 3D raymarching shaders - Feed audio volume into Simulation2D physics distance field evaluations - Remove var7 reservation assert in SdfSong and use audioVolume() for UI song pulsating - Add Audio Volume node to SDF node editor - Update MATH.md and AUDIO.md documentation

…lick, and inspector controls - Upgrade synth voice filters to 2-pole resonant TPT State Variable Filter (12 dB/oct) with dynamic attack Q bite and denormal protection. - Replace std::rand() in audio render loop with lock-free, branchless XorShift32 PRNG (fastNoise). - Normalize phase accumulator to [0.0, 1.0) to eliminate floating-point drift and inner-loop 2pi multiplications. - Redesign UI positive click into short, tactile mechanical switch click / thock with dual micro-transients and low-mid cavity body. - Implement organic sequential track shutdown on death (Lead -> Drums -> Pad -> Bass) with natural note ring-out and zero abrupt voice cutting. - Update node editor inspector with track play status badges, dynamic trigger sizing, and reset controls. - Update docs/AUDIO.md with DSP hardening, revised synthesizer channel diagram, and dynamic API methods.
…ck to resonant acoustic pop - Remove automatic music surge triggering on physical collisions in AudioEngine. - Remove impact energy tracking from PhysicsAudioEngine. - Lengthen UI positive click sound to 75ms with resonant acoustic pop in A4-A5 register without internal double-decay choke. - Update docs/AUDIO.md with revised UI positive click sound specifications. - Add vortex.json preset to sdf-node-editor assets.
