haudiotagger_fingerprint 0.1.0

haudiotagger_fingerprint: ^0.1.0 copied to clipboard

Features #

• New HaudioFingerprint.fingerprint(path) API for perceptual audio fingerprinting via file path
• New HaudioFingerprint.fingerprintFromBytes(bytes) API for web/WASM and in-memory audio
• New HaudioFingerprint.similarity(a, b) (plus similarityTo) returning a 0.0–1.0 content-match score
• Chromaprint-compatible fingerprints (preset_test2, same algorithm as fpcalc/AcoustID)
• Pure-Rust stack (Symphonia + rusty-chromaprint): no C dependencies, builds on all platforms including WASM
• Federated backend: FingerprintBackendImpl plus HaudioFingerprintBackend.registerWith, self-registering via dartPluginClass — installing this package wires Haudiotagger.fingerprint() with no imports or init calls

Dependencies #

• symphonia 0.6 for audio decoding (MP3, FLAC, Ogg Vorbis, WAV, AIFF, M4A/AAC/ALAC)
• rusty-chromaprint 0.3 for fingerprint calculation and comparison
• flutter_rust_bridge =2.13.0 for the Dart FFI bridge
• haudiotagger_interface ^0.1.0 (pure-Dart contract, zero native weight)

Platform Notes #

• Decodable formats: MP3, FLAC, Ogg Vorbis, WAV, AIFF, M4A/AAC/ALAC
• Not decodable: Opus, APE, WavPack, Musepack (no pure-Rust decoder)
• Independent package: separate Dart package, Rust crate, native libraries, and plugin classes
• Haudiotagger.fingerprint() (requires haudiotagger ^2.2.0) throws a helpful StateError when this package is not installed
