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.

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

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.

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

Make port velocity warning threshold (currently 17m/s) adjustable. Remove warnings until a better method is implemented. Explore better ways to track chuffing/port turbulence (air velocity doesn't account for port friction).

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.

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.

Allow setting the listening distance for SPL calculations. Currently fixed at 1 m; add options for 2, 3, 4, and 5 m so users can simulate response at their 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 on the color dot in the graph legend or enclosure editor to choose from 25 preset colors. Also allows switching between enclosures by clicking on legend items.

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.
