A high-performance PipeWire `filter-chain` audio DSP graph for the built-in speakers of the **MacBook Pro 15,1** (2018/2019 Intel T2) running Linux (`t2linux`).
> [!NOTE]
> [!NOTE]
> **Not a kernel driver.** This graph connects to WirePlumber's hidden `alsa_output.platform-sound.RawSpeakers` sink, delivering Apple-grade warm voicing, multiband dynamic control, driver crossover, FIR correction, and hard driver safety backstops.
