v0.19.1

[0.19.1] -- 2026-06-04

Fixed

• Benchmark test data missing in release builds (Issue #13) -- PyInstaller now collects src/meetandread/performance/test_data/* including benchmark.wav and ground truth files, fixing "Test clip not found" errors in release builds
• Speaker diarization fails in release builds (Issue #14) -- Removed soundfile dependency (which could not be bundled via PyInstaller after 8 attempts) and switched to Python's built-in wave module for WAV file I/O. This eliminates scipy.io.wavfile bundling issues and completely fixes ModuleNotFoundError in release builds. Supports standard 16-bit PCM WAV files (most microphones)

Added

• Speaker Diarization settings in Settings panel -- Three tunable controls added for speaker detection behavior:
  • Clustering Threshold (0.0-1.0, step 0.05) -- Controls speaker segmentation; higher values produce more speakers
  • Min Speech Segment (0.1-5.0s, step 0.1s) -- Minimum duration for speech segments before discarding
  • Min Silence Gap (0.1-5.0s, step 0.1s) -- Minimum silence duration before splitting speakers
• All settings persist immediately to config and restore on panel open

Changed

• Speaker diarization defaults -- Updated based on testing to reduce over-segmentation in noisy environments:
  • clustering_threshold: 0.6 → 0.5 (fewer false speaker splits)
  • min_duration_off: 0.5 → 0.8s (better for noisy rooms)
