SolAudioLab Virtual Headphones - Beta 0.5 Model Reference

Build target: Windows 64-bit VST3
Web data baseline: SolAudioLab V288.3
Headphone database: VH-2026.08.06-phase1
AutoEq commit: 7ae0f56d53074872b028649617a22bbb4232feb7

MODEL COUNTS
- MY HEADPHONES: 330
- TARGET: 408
- CONSUMER CHECK targets: 93
- TARGET type breakdown: 338 over-ear, 62 in-ear, 8 earbud

BETA 0.2.3 REGRESSION BASELINE
- Original MY HEADPHONES profiles preserved at the beginning: 100
- Original TARGET profiles preserved at the beginning: 200
- The build generator compares the original IDs, profile IDs, 14 filter-band
  values, and 121-point response data against the Beta 0.2.3 manifest before
  the Beta 0.5 build is allowed to continue.

DSP RULES
- Same-type maximum filter gain: +5 dB / -7 dB
- Cross-type maximum filter gain: +4 dB / -5.5 dB
- Cross-type difference strength: 72 percent before frequency-confidence weighting
- Cross-type targets use LISTENING REFERENCE behavior from the SolAudioLab web tool.
- Safety attenuation remains the largest positive filter-band gain plus 1 dB,
  with at least 0.5 dB of attenuation.

CONSUMER CHECK
The CONSUMER CHECK mark identifies selected common consumer listening devices
that are especially useful for mix-translation checks. In-ear fit, seal, ear
tips, ANC, adaptive processing, and device DSP can change the real result.

This file describes the Beta 0.5 test database. It is not a claim that the
plug-in exactly reproduces every individual listener or physical unit.


BETA 0.5 UI / STATE BEHAVIOR
- DSP/model data and the Beta 0.3 expanded database are unchanged.
- CONSUMER CHECK remains text-only. Clicking its text selects first, then opens info.
- LISTEN is a single-location TARGET <-> MY HEADPHONES toggle.
- Up to 6 recent source IDs and 6 recent target IDs are stored locally by stable ID.
- Recent history is UI state only and is not part of audio processing.
- The remote notice is fetched outside the audio thread from the fixed SolAudioLab
  HTTPS endpoint and accepts text/visibility/refresh-hours/SolAudioLab URL fields only.
- Remote notice failure has no DSP effect and falls back to cached/built-in UI text.
