audio_defect_detector 0.0.3

Pure Dart library to detect pops and clicks in WAV audio files using adaptive threshold analysis.

0.0.3 - 2026-04-13

• Licence change: relicensed from GPL-3.0 to Apache-2.0 (permissive, allows use in proprietary projects)

0.0.2 - 2026-04-13

• Breaking: analyseBytes(), analysePcm(), and analyseSamples() are now synchronous — they return AnalysisResult directly instead of Future<AnalysisResult>. Only analyseFile() remains async (file I/O).
• AIFF and AIFF-C format support (big-endian PCM and sowt little-endian variant)
• Signed 8-bit PCM support (used by AIFF)
• Auto-detection of AIFF files via magic bytes and .aiff/.aif/.aifc extensions
• Expanded test suite to 192 tests

0.0.1 - 2026-04-12

• Initial release
• WAV PCM (8/16/24/32-bit) and IEEE Float 32-bit support
• Pop and click detection with adaptive MAD threshold
• CLI tool audiodefect with text and JSON output
• Configurable sensitivity (low/medium/high)
• Per-channel or mono-summed analysis
• Raw PCM byte analysis via analysePcm() with PcmFormat descriptor
• Pre-normalised sample analysis via analyseSamples()
• Public median() and mad() statistical utilities
• decodePcmBytes() for manual PCM-to-float conversion
• CLI --raw mode with --sample-rate, --bit-depth, --channels, --float options
• Comprehensive test suite (153 tests)
• Security hardening: file size limits, WAV chunk validation, block alignment checks
• AIFF and AIFF-C format support (standard big-endian and sowt little-endian variant)
• Signed 8-bit PCM support (used by AIFF)
• Auto-detection of AIFF files via magic bytes and .aiff/.aif/.aifc extensions
