ARCHITECTURE: Subsystem Implementation

この audionoise_kernel は、原作の C 実装を「原子単位」で JS へ移植したものである。

LFO Diagnostic (tests/lfo_verify.c): 起動時に 32bit 位相アキュムレータの精度テストを実行。JS の Math.sin との誤差を計算し、dmesg に出力する。
Direct Form 1 Pipeline: 浮動小数点の計算誤差を「味」として利用する Linus 氏の設計を再現。
Stompbox UI: ペダルを踏んだ際の物理的なラッチ動作と、ノブ操作時の視覚的フィードバックを同期。
Score Source: Bad Apple!! MIDI from https://github.com/CalvinLoke/bad-apple (contains alstroemeria_records_bad_apple.mid).
