v0.9.4 · 11 Nov 2026 — Photoreal landing hero (clearcoat paint, rubber, glass, chrome, studio floor and contact shadow). The landing paints first with a still poster so phones are not blocked by the 3D module. Inside cabin: the 3D view fills the tool area and resizes with the window; the Cabin field panel is a hideable overlay and no longer leaves a black gap. v0.9.3 — Library “Your vehicles” rows are light site-style cards.
v0.9.2 · 11 Nov 2026 — Hero car is zoomed to fill about 75–80% of the frame. Vehicle chips and a make/model/year field look up a local list and save to a per-device database, including an optional STL that opens in the pod maker and the library. Place-in-car and car hotspots stay in the builders. Sound / Tune is on every tool toolbar. Measure is guarded so it cannot crash before a session starts.
v0.9.1 · 11 Nov 2026 — Light shop-front landing matched to streetsoundvision.com.au, official logo, homepage tool cards with real previews, and enclosure cards from the existing cutaway artwork.
v0.9.0 · 11 Nov 2026 — Rebranded to SSV · Street Sound & Vision. A shop-front landing page (3D car, enclosure-first catalogue, workshop tool gates) and a portal sidebar with Home. Click a zone on the car to assign gear; every builder has Place in car. System Designer is a full-screen dark canvas with live amp load and animated signal flow. Remaining white pages are overlay shells. Real SSV products from the shop catalogue (read-only crawl of streetsoundvision.com.au) can be selected in the builders. Subscription is a shop setting and is off by default — no paywall.
v0.8.0 · 10 Nov 2026 — Box Lab MAKE: 3D Print splits any enclosure in half, to printer-bed size, or with draggable cut planes, with lip or dowel joints, per-part highlight, per-part and zip STL, and a watertight check. CNC nests timber panels on a sheet, offsets toolpaths (including driver cut-outs and ports) by the bit radius, downloads GRBL G-code (.nc) and DXF, and plays an animated 3D simulator (gantry, material removal, play / pause / speed / scrub, time estimate). Both are top-toolbar modes using the overlay pattern. Works for timber boxes (sealed, ported, 4th / 6th order, IB baffle) and printed shells / spiral pods (Print is the make path; CNC explains that those are printed, not sheet goods).
v0.7.0 · 10 Nov 2026 — The Car tab is the home screen: the original 3D car designer (pick a vehicle and body, X-ray or exterior, place speakers, amp, battery, DAP and the sub box on the car, with cable routes and a wiring estimate). Everything from System, Box Lab, Battery and Crossover is placed and wired into that one car. Inside cabin opens the Cabin Sound Map in the same view (RTA, sonar, listening field, enter the cabin). Combined analysis is on the toolbar. Shop branding is now SSV.
v0.6.2 · 10 Nov 2026 — Box Lab: an always-visible 3D Print button (top right of the toolbar) opens the print overlay for whatever is on screen — printer bed size, part list with a preview and 3D highlight, Download all STL (zip) plus each part’s STL, estimated print size and volume, and the plan sheet. An Export button next to it gives the DXF cut files and the cut list.
v0.6.1 · 10 Nov 2026
- Full-screen 3D in Box Lab. The enclosure fills the window under a slim top bar — no long page of settings with a small preview in the middle.
- Top toolbar: Templates, Driver, Box, Ports, Spiral, Numbers, Graph, Plans / Export, Trunk. Click a button to open that panel as a floating overlay on the 3D; click it again (or Close) to hide it. Only the panel you asked for is shown. You can still orbit the 3D behind and around it.
- Template picker is an overlay. Click a card and that design loads immediately in the full-screen 3D; the picker closes. No scrolling to find the result.
- The app is a fixed-viewport tool (the window itself does not scroll). Overlays scroll inside themselves if they are long. On a phone, panels open as a bottom sheet.
- Same maths, DXF, STL, plan sheet and spiral pods as v0.6.0 — this is a layout change only.
v0.6.0 · 10 Nov 2026
- Spiral pod designer in Box Lab (new "Spiral pod" type and three template cards: 1-way, 2-way, 3-way). A golden / log-spiral shell (growth per quarter turn, default φ = 1.618, number of turns, wall, front collar, tip Ø or self-similar tip, flattened section, whorl gap, neck length) coils up behind the driver and closes at the tip. The driver sits in the mouth and fires forward.
- Uses the same driver panel as the box designer (Fs, Qts, Qes, Qms, Vas, Re, Le, Sd, Xmax, sens, power, displacement) plus its own mid and tweeter specs. New example 3", 4" full-range, 5.25" and 6.5" mid-woofer presets, a 3" mid and a 1" dome tweeter (generic examples, not real products).
- Honest acoustics: the spiral is modelled as a lossy, closed-end tapered transmission line (exact conical Webster segments in an ABCD chain, wall loss and stuffing) loading the back of the cone. Graphs from 20 Hz to 20 kHz: system sum, each driver after the crossover, the woofer with no crossover, the same-volume sealed box (dashed), impedance and cone excursion. Shows line resonances, F3/F6, Qtc/Fc and what is simplified.
- 2-way / 3-way with a passive crossover (1st / 2nd / 3rd order, LR or Butterworth, L-pads, woofer Zobel, polarity auto or manual), loaded with the real driver impedances. Use the pod's own values or the Crossover tab's; load from or copy to the Crossover tab with one click.
- Print it: watertight STL parts split to your bed size (default 300 mm) with overlap-lip joints, driver cut-out with screw holes, wire windows through flat pads, bezel ring, tripod hub with leg sockets, legs, posts between pods or a desktop cradle. Parts are laid flat for the bed. Plus a section DXF (CUT / ENGRAVE / DIM), an inside-air check STL and a printable plan sheet.
- Photoreal looks: sandstone or concrete print, matte, gloss or plain PLA, with a brass-look, black or chrome bezel and tripod.
v0.5.0 · 10 Nov 2026
- Box Lab templates: start from Infinite baffle (IB / infra baffle), Sealed, Ported round, Ported slot / L-slot, 4th- and 6th-order bandpass, 4th-order isobaric (clamshell), 6th-order isobaric (tunnel-loaded) or a 3D-printed shell. Each card shows a cutaway render of that design from the app's own 3D model, with the chambers, ports, sub positions and arrows for where the sound goes.
- Infinite baffle board designer: sub cut-outs, screw holes, perimeter fixing holes, engraved seal band, rear-deck or seat-back mounting, trunk air volume in the model. DXF (CUT / ENGRAVE / DIM) and STL of the board.
- Isobaric pairs in 4th and 6th-order bandpass: clamshell (face-to-face, spacer rings, outer sub wired reversed) or tunnel-loaded (tunnel box, in phase). Modelled as one equivalent sub (Vas ÷ 2, same Fs / Qts, 2 × moving mass, 2 × power).
- 3D-printed flared shell: egg-shaped shell with a flat front plate and a flared port bell out the back. Inside volume comes from the same profile as the mesh. Exported as watertight STL parts split into sections (and halves / quarters to fit your printer bed), plus a profile DXF.
- More realistic 3D: paint, gloss and carpet finishes, printed-layer look for the shell, a fibre-textured cone with a gloss trim ring, contact shadows, and round ports that now look like ports (dark bore, satin flared flange with screws). New "Sound path" toggle.
v0.4.0 · 10 Nov 2026
- New Box Lab on the Box tab: a realistic 3D enclosure in MDF or birch ply with real board thickness, a modelled sub (cone, surround, dust cap, magnet), flared round, slot or L-shaped slot ports, window braces, double baffle and trunk wedge. Explode slider, X-ray (air volumes + port air path), cutaway, dimensions in mm or inches.
- Sealed, ported, 4th-order and 6th-order bandpass, with gross / net / displacement volumes, Qtc / Fc / F3, Helmholtz port length with end correction, port air speed (chuffing warning above about 17 m/s) and cone excursion vs Xmax.
- Thiele-Small response graph at 1 W / 1 m and at your amp power from the System tab, with an optional cabin-gain overlay and a sealed vs ported compare. Drag the handles to set F3 and Fb: the box volume solves and the 3D box resizes live.
- Trunk fit with a sloped seat back and collision warnings. Build plans: cut list, 2400 × 1200 sheet nesting, DXF R12 per panel (layers CUT / ENGRAVE / DIM), watertight STL (hollow shell or separate panels) and a printable plan sheet.
v0.3.0 · 10 Nov 2026
- New Battery tab. A lithium cell library: Yinlong LTO 66160 40 / 45 Ah, EVE LF280K and LF105 LFP, Na-ion 18650, plus typical NMC, LiPo and car-audio bank modules. Each cell is tagged Car audio / Solar / Both, with datasheet links, and values not on a datasheet are marked "typical".
- Pack builder: set S and P, drag new, aged, weak or low cells into slots on a busbar layout. It shows volts, Ah, Wh, continuous and peak amps, internal resistance and weight, with warnings for 12 V, 24 V and 48 V systems.
- System parts: BMS, active or passive balancer, ANL / MEGA main fuse, amp fuse, shunt meter, isolator, alternator or charger, solar MPPT + panel, and cable resistance.
- Time simulation (30 / 60 / 120 min): pack V, SoC, current and every cell voltage with a playhead and Play. The out-of-balance cell is highlighted, the balancer is animated, there is a bass-hit sag graph, and the amp load comes from the System tab with an adjustable crest factor.
- Circuit Lab: supply voltage presets (12 / 14.4 / 24 / 36 / 48 V or custom), a DAP distribution block with fused outputs, a DC-DC buck/boost converter, and "Use as Circuit Lab supply" to drop the battery pack in live.
v0.2.1 · 10 Nov 2026
- Speaker polarity per driver (normal / REVERSED) with toggles on the crossover graph and an Auto reset. Defaults: 1st order all normal; 2nd order 2-way tweeter reversed; 2nd order 3-way mid reversed; 3rd-order Butterworth tweeter reversed (2-way) or mid + tweeter reversed (3-way).
- Fixed: the 3-way 12 dB/oct acoustic sum no longer cancels at the mid/tweeter crossover.
- The board wires reversed speakers + to − with a red REVERSED tag, and the Build guide tells you to wire them in reverse.
v0.2.0 · 10 Nov 2026
- New Circuit Lab: a real-looking breadboard with every hole, + / − rails and a parts drawer (colour-banded resistors, film / electrolytic / bipolar caps, air-core coils, LEDs, diodes, switch, fuse, trim pot, wires, 12 V supply, amp output, tweeter / mid / woofer).
- Drag parts into holes, draw wires hole to hole, rotate (R), delete (Del), undo / redo, pan and pinch-zoom.
- POWER switch runs a live simulation: voltage, current and power on hover, multimeter probes, moving current dots, glowing LEDs, smoking resistors, blowing fuses and reverse-polarity warnings.
- Crossover tab now builds your 2-way / 3-way on the breadboard automatically, with a step-by-step Build guide.
- Interactive crossover graph: drag the Bass / Mid / Tweeter crossover handles, pick 6 / 12 / 18 dB/oct, L-pad each driver 0 / −3 / −6 / −9 dB — parts, colour bands, impedance curve and parts list update live. Tone generator moves the speaker cones.
- Fixed: 18 dB/oct (3rd-order) networks now use the correct series–shunt–series ladder; option buttons always highlight the current setting.
v0.1.0 · 10 Nov 2026
- ACW shell from the live Car Audio Hub look — shop catalogue and tenant branding removed.
- System Designer with live ohms / watts and amp-stable warnings.
- Passive crossover builder with complex-impedance load, proper schematic legs, and Z-curve.
- Box Designer (sealed / ported / bandpass) with STL + DXF export.
- In-car sound, competition check links, and rulebook library.
