 ## Priority 4: Audio System Enhancements [LOW PRIORITY]
 
-1. **GPU-Accelerated PCM Synthesis:**
+1. **`synth.cc`: use `ola_decode()` from `src/audio/ola.h`** — the OLA decode logic in
+   `synth_render()` is currently inlined for frame-by-frame lazy decoding. Refactor to
+   call `ola_decode()` for consistency with `spectool` and the test (requires decoupling
+   the per-frame lazy path, e.g. decode a full block on demand then serve samples).
+
+2. **GPU-Accelerated PCM Synthesis:**
    - Compute shader for direct PCM generation (bypass spectrogram)
    - Write to compute buffer, readback to synth
