Overview

This release adds filter and parametric EQ support, manual T/S parameter editing, and various simulation improvements.

New Features

Filters & Parametric EQ

Requested by @gnkaudio

• High-Pass and Low-Pass Filters: Butterworth and Linkwitz-Riley options at 12dB/oct and 24dB/oct slopes
• Parametric EQ: Add boost or cut at specific frequencies with adjustable Q factor
• Graph Integration: Filters and PEQs are displayed directly on the SPL graph with interactive handles
• Right-Click to Add: Right-click anywhere on the SPL graph to add a filter or PEQ at that frequency
• Drag to Adjust: Drag filter handles to change frequency, drag PEQ handles to adjust frequency and gain, drag Q handles to adjust bandwidth

Manual T/S Parameter Editing

Requested by r/hedekar

• Edit Driver Parameters: Modify any Thiele-Small parameter for custom drivers or to match measured values
• Direct Input: Enter exact values for Fs, Qts, Vas, Xmax, and other parameters

Simulation Improvements

• Filters now correctly affect excursion, port velocity, and SPL calculations
• Max SPL graph remains unaffected by filters (shows true system capability)
• Fixed SPL calculation accuracy (was reading ~3dB high)
• Frequency axis capped at 400Hz across all graphs for better focus on subwoofer range

UI Improvements

• EQ edit mode toggle on SPL graph header
• Delete buttons on filter and PEQ popups for quick removal
• Improved tooltip display for Max SPL showing limiting factor (mechanical vs thermal)
