+# Change: update audio playback speed control
+
+## Why
+当前悬浮播放控件和音乐播放器工具缺少统一的播放速度入口，语音朗读的语速又单独存在于设置面板，导致用户无法在播放时直接调整速度，也容易出现播放控件与设置值不一致的问题。
+
+## What Changes
+- 为悬浮播放控件和音乐播放器工具新增统一的播放速度入口
+- 在共享播放服务中增加普通音频与语音朗读的独立速率状态
+- 让语音朗读速率与设置中的 `tts.rate` 双向同步
+
+## Impact
+- Affected specs: `canvas-audio-playback`
+- Affected code:
+  - `packages/drawnix/src/services/canvas-audio-playback-service.ts`
+  - `packages/drawnix/src/components/audio-node-element/CanvasAudioPlayer.tsx`
+  - `packages/drawnix/src/tools/tools/music-player/MusicPlayerTool.tsx`

+## MODIFIED Requirements
+
+### Requirement: Shared playback modes for audio players
+The system SHALL provide shared playback controls for the global floating audio player and the music player tool.
+
+#### Scenario: Switch playback speed from the floating player
+- **GIVEN** an audio or reading queue is active
+- **WHEN** the user changes playback speed from the floating player dropdown
+- **THEN** the system SHALL update the shared playback speed state
+- **AND** the music player tool SHALL reflect the same selected speed
+
+#### Scenario: Switch playback speed from the music player tool
+- **GIVEN** an audio or reading queue is active
+- **WHEN** the user changes playback speed from the music player tool dropdown
+- **THEN** the system SHALL update the shared playback speed state
+- **AND** the floating player SHALL reflect the same selected speed
+
+#### Scenario: Sync reading speed with TTS settings
+- **GIVEN** the active queue is a reading queue
+- **WHEN** the user changes playback speed from either player entry
+- **THEN** the system SHALL update the current reading playback speed
+- **AND** SHALL sync the same value to `tts.rate`
+
+#### Scenario: Reflect external TTS speed changes during reading
+- **GIVEN** a reading queue is active
+- **WHEN** `tts.rate` changes from the settings panel
+- **THEN** the shared reading playback speed SHALL update
+- **AND** both player entries SHALL reflect the latest reading speed
