Armiger Plugin #4 — Cross-Head Audio Language & Anime Dub Guard (armiger-audio-guard)

Couples Armiger's neural title_language and lang heads with linguistic & tracker-tag disambiguation to lift binary English-vs-Foreign audio language accuracy on oct15_confirmation (N=545) from 96.88% to 97.80% (92.75% 3-class, N=772).
Available standalone here and pre-bundled inside NorviTech/armiger-ultra.

What armiger-audio-guard Solves

Standard regex parsers (RTN, Parsett, GuessIt, PTN) and single-head classifiers systematically fail on five recurring multilingual torrent patterns:

1. Romance-Language .en. Prepositions: Titles like Le.Voyage.dans.la.Lune.1902.1080p.mp4 or Les.Quatre.Cents.Farces.du.Diable.1906.mkv contain the Spanish/French word en ("in"). Case-insensitive .en. tokenizers misclassify these as English audio.
2. <Foreign>.ENG.Sub Releases: In Movie.Title.ITA.ENG.Sub.2025.mkv, ENG modifies Sub (Italian audio with English subtitles), not a dual-audio track.
3. Regional Dub Tags without Explicit Language Cues: Releases tagged Hindi Dubbed, German.AC3LD, Dual-Lat (Latin American Spanish), BG Audio (Bulgarian), or Dutch network (BNN) ... NL.
4. Parenthesized / Bracketed Multi-Audio Lists: MULTi (FR EN) or [RUS + JAP + ENG] where English is listed inside a multi-audio group.
5. Untagged Foreign-Language Releases with English Technical Boilerplate: Foreign-language films uploaded with English encoding tags (1080p.WEBM.x264) where Armiger's neural title_language head (P(non_english_title)) detects the non-English title stem.

Quickstart

from audio_language_guard import apply_audio_language_guard, classify_audio_and_anime_dub

# Example 1: Spanish preposition '.en.' with high neural foreign-title probability
p_en = apply_audio_language_guard(
    raw_name="Le.Voyage.dans.la.Lune.1902.1080p-dual-lat.mp4",
    p_en=0.62,
    p_title_foreign=0.96,
)
print("Adjusted P(English audio):", p_en)  # -> 0.10 (Foreign audio)

# Example 2: Multi-audio release with explicit (FR EN)
print(classify_audio_and_anime_dub(
    raw_name="Show.Name.S01.MULTi (FR EN) [1080p]",
    p_en=0.38,
    p_anime=0.02,
    p_title_foreign=0.15,
))
