# Superseded — not folded into `openspec/specs/`

**Date superseded**: 2026-05-15
**Superseded by**: `openspec/changes/enterprise-audio-plugins-fx/`

## Why

This proposal shipped twelve `AudioPlugin` subclasses built on the now-superseded monolithic `@suaveplan/audio-engine`. It uses the pre-tier `browser/audio/audio-plugins-fx` target path and is browser-only.

The replacement (`enterprise-audio-plugins-fx`) is universal: every plugin implements `BlockProcessor` from `@suaveplan/audio-core` and optionally `createAudioNode()` for browser-native Web Audio rendering. The same plugin code therefore runs in server, offline, and worklet contexts as well as the browser.

No code was implemented for this proposal.
