+## Priority 4: Audio System Enhancements [LOW PRIORITY]
+
+Extended audio capabilities for sample assets and procedural synthesis.
+
+**Sub-tasks:**
+
+1. **MP3 Sample Assets:**
+   - Integrate miniaudio for MP3 decoding
+   - Add ASSET_*.mp3 support to asset_packer
+   - Convert to PCM in AssetManager or synth on load
+   - Use case: Compressed sample libraries
+
+2. **GPU-Accelerated PCM Synthesis:**
+   - Compute shader for direct PCM generation (bypass spectrogram)
+   - Write to compute buffer, readback to synth
+   - Use case: Real-time modulation, complex waveforms
+   - Lower latency than spectrogram path
