# InfinityDM Audio Asset Licenses

This directory contains optimized browser-ready audio derived from external
source packs. Runtime code loads only local `/assets/audio/...` paths; it never
hotlinks source marketplaces or repositories.

InfinityDM uses edited excerpts. Four tracks were loudness-normalized and
converted into 60-second circular-crossfade loops. "Aftermath" was trimmed,
faded, and loudness-normalized into a short non-looping transition. Exact
source pages, source hashes, transformation recipes, optimized hashes, decoded
durations, loop-boundary checks, and file sizes are recorded in
`frontend/audio-source-manifest.json`. Canonical rebuilds use the encoder version,
platform, and executable SHA-256 pinned in that manifest; other platforms may
validate the committed outputs but must not mint replacement hashes.
