Roadmap

Support sub-liter enclosures (down to 0.01 L), small ports (down to 1 mm), and very large systems (up to 100,000 L) for multi-driver arrays.

Show system Q factor (Qtc) for sealed enclosures to help users understand damping characteristics and alignment type.

Show mechanically and thermally limited maximum SPL to help identify power handling limits and excursion constraints.

Allow configuring multiple ports with different dimensions (circular and slot) for more complex enclosure designs.

Allow users to expand/contract individual graphs between 1 and 2 columns for better visibility and comparison.

Toggle between light and dark themes with theme-aware colors, logos, and components. Light mode uses a deep blue accent for optimal contrast.

High-pass, low-pass, and parametric EQ with interactive graph controls. Filters affect excursion, port velocity, and SPL calculations.

Edit Thiele-Small parameters directly for custom drivers or to match measured values.

Support for passive radiator enclosures as an alternative to ported designs, with dedicated PR excursion graphs and tuning options.

Simulate enclosures with multiple identical drivers (e.g., dual subwoofers) with proper acoustic coupling and combined response calculations.

Support for imperial units (inches, feet, cubic feet) in addition to metric units for enclosure dimensions and driver specifications.

Automatically calculate effective enclosure volume by accounting for driver displacement, port volume, and bracing. This provides more accurate simulation results.

Allow users to set port length directly and have the simulator calculate the resulting tuning frequency, in addition to the current method of setting tuning frequency.

Enhance the user experience when manually entering Thiele-Small parameters, with better validation, clearer unit labels, and improved input methods.

Add a per-enclosure T/S adjust mode with temporary sliders for parameters like Qts, Fs, Vas, and Bl so users can explore graph changes without modifying the underlying driver model.

Simulation support for 4th-order and 6th-order bandpass enclosure designs.

Share enclosure designs via URL. Select which enclosures and drivers to include, then share a link that others can view and import into their own simulator.

Customize graph axis ranges and scales to focus on specific frequency or amplitude ranges.

Expand the built-in driver library with more manufacturers and models.

Removed unnecessary padding and cards around graphs to maximize screen real estate for data visualization.

Click on a graph to lock the cursor at a specific frequency, with visual indicator and unlock button. Cursor position is remembered when mouse leaves the graph.

Replaced floating tooltips with integrated legend display showing live values, reducing visual clutter and improving performance.

EQ editing is now per-graph, with context menus for adding filters and parametric EQ points only appearing when in EQ edit mode.

Graph animations now run 2.5x faster for more responsive interactions.

Improved grid line visibility in dark mode for better graph readability.

Power input moved to a pinned bottom bar with improved visibility and accessibility.

Enhanced passive radiator management interface.

Reorganize T/S parameter input form to show required parameters first, making it easier to enter essential values.

Improve the UX for switching between enclosures and duplicated enclosure variants to make comparisons more intuitive and discoverable.

Show the three-dot context menu on enclosure and driver configuration items at all times, not just on hover.

Hide debug graphs from the graph selector unless a debug mode is enabled, reducing clutter for regular users.

Display reference efficiency (η0) as a calculated parameter to help users understand driver efficiency characteristics.

Allow users to customize graph line thickness for better visibility and personal preference.

Investigate and fix issue where SPL appears as a straight line above resonance, potentially related to Le (voice coil inductance) usage in calculations.

The port velocity warning level is adjustable, starting at 17 m/s.

Add Linkwitz Transform as an EQ option for extending low-frequency response in sealed enclosures.

Add high and low shelf EQ options to the EQ panel.

Add a dedicated graph showing group delay across the frequency spectrum to help identify phase-related issues.

Added a schematic graph to visualize the electro-acoustic signal chain and enclosure path layout. Currently marked as beta while the diagram model and labels are refined.

Provide alternative input methods for power calculation, allowing users to specify voltage and resistance instead of just power.

Add a dedicated amplifier load graph in VA (apparent power) across frequency, with optional current overlay for amplifier demand analysis.

Add support for Xmech and Xdamage parameters. Allow configurable xmax warning level on excursion graph and on pr excursion graph.

Add configurable air velocity warning level on port velocity graph.

Fix alignment issue where power slider value display doesn't properly align with the slider position. Surprisingly hard to fix!

Reorganize menu structure to make driver management more discoverable and accessible.

Made inactive checkboxes more visible in light mode with better contrast.

Redesigned the EQ panel with a unified filter list. Single "Add Filter" button to add high-pass, low-pass, or parametric EQ filters. More compact layout with less wasted space.

Added a dedicated EQ graph workflow so filter response and edits are easier to inspect and tweak in one place.

Set the listening distance for SPL calculations (1 m by default) to see the response at your actual listening position.

Allow modelling power separately per plot instead of one global signal power, making quick A/B comparisons easier across enclosure variants.

Click the color dot in the graph legend or enclosure editor to pick one of 25 presets or any custom color. Clicking a legend item also switches between enclosures.

Support for dual voice coil drivers with series/parallel wiring options. Automatically detects DVC drivers from WDR files and calculates effective impedance based on wiring configuration.

Import full enclosure designs, drivers, and passive radiators from Unibox spreadsheet databases (.xlsx). Multi-step flow with sheet detection, tabbed review (enclosures/drivers/PRs), T/S parameter validation, and batch import with warning indicators. Bandpass enclosures marked as unsupported but drivers still importable.

Refreshed the simulator UI with clearer contrast/hierarchy and a reorganized menu/header structure for faster access to key controls.

Added direct drag interactions to reposition graph tiles and resize them in the grid layout.

Sidebars can be repositioned via drag-and-drop. Pin/unpin controls were removed to simplify behavior and reduce confusion.

Create Driver now supports pasting raw manufacturer spec text and extracting T/S parameters with unit conversion and consistency checks before populating the editor.

Added compact per-enclosure chips in the sidebar for volume, power, and alignment frequency, including power-level tinting for quicker at-a-glance comparisons.

Simplified enclosure modeling by keeping one active driver setup per enclosure, with duplication used for clear A/B comparisons.

Added a docs area and in-product guidance pages for onboarding and advanced workflows.

Display the first-order resonances of ports so users can spot potential upper-band issues and make better tuning tradeoffs.

Allow arrow key adjustments on numeric inputs for faster fine-tuning without needing to retype values or drag controls.

Make the enclosure configuration panel easier to find, read, and use with clearer hierarchy, better visibility, and more intuitive interactions.

Sign in to keep cloud workspaces, version history and shared designs across devices. Suggested by Pascal Pharmacon.

Add a slider under each enclosure volume input (main, bandpass front, bandpass-6 rear) so users can sweep volume without retyping. Exponential 1–1000 L scale with deferred commit for responsive dragging.

Open WinISD driver (.wdr) and project (.wpr) files, and export drivers and projects back to WinISD.

Connect Claude, ChatGPT or another MCP client to your account so it can build workspaces, run simulations and show graphs, and watch it work in the open workspace.

Publish designs to a public gallery and your profile, with graph previews, notes and links.

Undo and redo with Cmd+Z / Ctrl+Z, and restore any saved version of a workspace.

Save and pin tile layouts, pick graph colors, and choose or build an app theme.

Select several enclosures to act on together, reorder them, and move or copy them between workspaces.

Free sealed, ported, subwoofer box, box volume, port length and port velocity calculators that open their result in the simulator.

An optional baffle step shelf, set from the baffle size and driver position in the Baffle Layout tile.

Front-loaded, back-loaded, tapped, offset-driver, stubbed, compound, multiple-entry and Paraflex horns, with per-span stuffing, diagnostics along the path, Max SPL and Hornresp export. Badged Alpha while it settles.

Import REW, FRD, ZMA or CSV measurements, up to 24 per workspace, and compare them with the simulation.
