+# Next-Gen Audio DSP Architecture: Compressed-Chain "Digital Surround" (Active Crossover) Engine & Multi-Laptop Ecosystem
+
+This document provides a comprehensive technical blueprint of the **Next-Gen Audio DSP Engine** implemented in `mbp15-1-audio-dsp`. The system delivers studio-grade, zero-latency audio performance for Linux laptops, outperforming factory OEM macOS/Windows DSP stacks while remaining fully open-source and hardware-portable.
+
+> ### 📻 "Digital Surround" Marketing vs. Active Digital Crossovers
+> In consumer laptop marketing, multi-speaker setups are frequently advertised under buzzwords like **"Dolby Atmos"**, **"3D Digital Surround"**, or **"Spatial Audio"** to imply multi-channel cinema sound. In real-world acoustic engineering, this feature is an **Active Multi-Band Digital Crossover Engine**. Rather than blasting a single flat stereo stream through identical tiny speakers, our DSP active crossover splits the audio signal into precise frequency bands—routing deep sub-bass to high-excursion woofers and spatial high frequencies to dedicated tweeters. This discrete multi-driver time and frequency alignment eliminates inter-modulation distortion, expands the physical soundstage, and delivers the immersive room-filling audio experience that consumer brands market as "Digital Surround."
+
+---
+
+## 🏛️ 1. Architectural Highlights
+
+* **⚡ Single-Stage Compressed-Chain FIR Engine:** Collapses all linear time-invariant (LTI) stages—User EQ, Voicing EQ, Linkwitz-Riley crossover high-pass filters, and driver impulse responses—into single composite FIR impulse files.
+* **⏱️ 5.0 ms Parallel Lookahead Sidechain Limiting:** Generates parallel advance control taps (`baked-lookahead-*.wav`) that feed peak warnings to post-convolver limiters **5.0 ms ahead of the physical audio**, adding **0.0 ms of buffer delay** to the listener's main audio path.
+* **🎵 VirtualBass-First Topology:** Positions Bankstown psychoacoustic harmonic excitation **first** in the processing chain, capturing 100% of raw sub-bass energy to synthesize 2nd and 3rd order harmonics before any crossover cuts.
+* **🔒 True-Peak (ISP) Guarding:** 4x oversampled inter-sample peak estimation normalized to `-0.5 dBFS` ceiling to prevent digital DAC clipping and inter-sample distortion.
+* **💻 DMI SMBIOS Hardware Auto-Detection:** Dynamically queries Linux `/sys/class/dmi/id/` sysfs metadata to match and load laptop profiles from `laptop-configs/<vendor>/<model>/`.
+* **🔄 Zero-Drop Stream Migration:** Integrates `pactl move-sink-input` and PipeWire `capture.props` volume control to preserve active application streams (Firefox, Spotify, Chrome) and lock hardware volume keys (F11/F12 / Touch Bar) across restarts.
+
+---
+
+## 🔬 2. Compressed-Chain Single-Stage FIR Engine
+
+### 2.1 LTI Stage Collapsing
+Traditional laptop DSP pipelines cascade 10 to 20 separate IIR biquads and convolver stages, consuming heavy CPU cycles and adding phase distortion. The Next-Gen Engine uses standard-library Python ([`bake-graph.py`](file:///home/steve/w11/mbp15-1-audio-dsp/bake-graph.py)) to perform single-pass LTI convolution that bakes User EQ, Voicing EQ, and Crossover filters directly into the 4-channel driver convolvers:
+
+$$\text{FIR}_{\text{baked}}(t) = \text{EQ}_{\text{user}}(t) * \text{EQ}_{\text{voicing}}(t) * \text{EQ}_{\text{crossover}}(t) * \text{IR}_{\text{driver}}(t)$$

+```
+
+### 2.2 Single-Pass FIR Baking Pipeline Process
+The FIR baking process in [`bake-graph.py`](file:///home/steve/w11/mbp15-1-audio-dsp/bake-graph.py) folds static LTI processing stages, latency reduction, target curves, and true-peak guarding directly into composite `.wav` impulse responses:

+    G --> H["baked-woofers-*.wav / baked-tweeters-*.wav<br/>(Single-Pass Baked Driver FIRs)"]
+```
+
+### 2.3 Post-Convolver Quad-Driver Safety Limiting
+To prevent speaker cone over-excursion and thermal overload without altering frequency response:
+
+1. **Direct Terminal Measurement:** Fast lookahead limiters (`wlim` and `tlim`) operate directly on the 4 post-convolver driver channels, accurately measuring the exact equalized waveform present at the driver terminals.
+2. **Dedicated Driver Ceilings:** Woofers (`wlim`) and Tweeters (`tlim`) have independent brickwall peak ceilings (`-2 dBFS` for woofers, `-1 dBFS` for tweeters) that guard against hardware driver clipping without squashing tonal dynamics or frequency response balance.
+3. **Zero Added Listener Latency:**
+   * Post-convolver limiters (`wlim` and `tlim`) receive peak warnings 5.0 ms before the audio reaches the speaker drivers.
+   * **Added buffer latency for the listener: `0.0 ms`.**
+

+
+## 💻 3. Multi-Laptop Profile Hierarchy & Auto-Detection
+
+### 3.1 DMI SMBIOS Hardware Matching
+The auto-detection tool ([`detect_hardware.py`](file:///home/steve/w11/mbp15-1-audio-dsp/detect_hardware.py)) queries the Linux Kernel DMI sysfs interface:
+
+* `/sys/class/dmi/id/sys_vendor` (e.g., `Apple Inc.`, `Dell Inc.`, `LENOVO`)
+* `/sys/class/dmi/id/product_name` (e.g., `MacBookPro15,1`, `XPS 15 9520`)
+
+`detect_hardware.py` matches these strings against `profile.json` metadata in the profile tree.
+
+### 3.2 Repository Directory Structure (`laptop-configs/`)
+
+```text

+| `--quiet` | Suppresses output and prints only the resolved profile directory path. |
+

+
+## 🎛️ 4. Terminal EQ Tuning & Live Graph Merging
+
+### 4.1 Single-Line Formatted `user_eq.json`
+The terminal EQ tuning utility ([`eq.py`](file:///home/steve/w11/mbp15-1-audio-dsp/eq.py)) formats [`user_eq.json`](file:///home/steve/w11/mbp15-1-audio-dsp/user_eq.json) with single-line band alignment matching `user_eq.example.json`:
+
+```json
+{
+    "enabled": 1, "mode": 0, "g_in": 1.0, "g_out": 1.50,
+    "ft_0": 5, "f_0": 70.0   , "g_0": 1.26, "q_0": 0.7, "s_0": 0,
+    "ft_1": 1, "f_1": 110.0  , "g_1": 1.26, "q_1": 1.0,
+    "ft_2": 1, "f_2": 315.0  , "g_2": 1.00, "q_2": 1.0,
+    "ft_3": 1, "f_3": 1000.0 , "g_3": 1.00, "q_3": 1.0,
+    "ft_4": 1, "f_4": 2500.0 , "g_4": 1.00, "q_4": 1.0,
+    "ft_5": 1, "f_5": 6000.0 , "g_5": 1.00, "q_5": 1.0,
+    "ft_6": 3, "f_6": 10000.0, "g_6": 0.89, "q_6": 0.7,
+    "ft_7": 3, "f_7": 16000.0, "g_7": 0.89, "q_7": 0.7, "s_7": 0
+}
+```
+
+### 4.2 Unified `user_eq.json` Graph Merging
+In [`apply.sh`](file:///home/steve/w11/mbp15-1-audio-dsp/apply.sh#L82-L95), `user_eq.json` is merged into `$GRAPH_SRC` via `jq` for **both `--bake` and un-baked pipelines**:
+
+```bash
+if [ -f "$OVERRIDE" ]; then
+    jq --slurpfile ov "$OVERRIDE" \
+       '(.["filter.graph"].nodes[] | select(.name == "user_eq") | .control) = $ov[0]' \
+       "$GRAPH_SRC" > "$MERGED"
+fi
+```
+
+This guarantees that user EQ gain adjustments and preset switches immediately affect live playback!
+
+---
+
+## 🔀 5. Interoperability & Stream Migration
+
+### 5.1 PipeWire Volume Control Binding
+`graph.json` exposes `loudness:volume` control directly inside `capture.props`:
+
+```json
+"capture.props": {
+    "node.name": "audio_effect.t2-151-speakers",
+    "media.class": "Audio/Sink",
+    "priority.session": 2500,
+    "priority.driver": 2500,
+    "capture.volumes": [
+        {
+            "control": "loudness:volume",
+            "min": -65.0,
+            "max": 0.0,
+            "scale": "cubic"
+        }
+    ]
+}
+```
+
+This allows desktop volume daemons and hardware media keys (**F11 / F12 / Touch Bar**) to lock directly onto the DSP Speakers virtual sink.
+
+### 5.2 Zero-Drop Stream Migration
+Upon cold restart of `wireplumber.service`, [`apply.sh`](file:///home/steve/w11/mbp15-1-audio-dsp/apply.sh#L188-L197) iterates over active PulseAudio/PipeWire sink inputs and migrates them to the new DSP sink:
+
+```bash
+if have pactl; then
+    pactl list short sink-inputs | awk '{print $1}' | while read -r stream_id; do
+        pactl move-sink-input "$stream_id" "audio_effect.t2-151-speakers"
+    done
+fi
+```
+
+Running `./apply.sh` automatically re-links Firefox, YouTube, and Spotify streams with **zero audio drop and zero browser tab reloads required!** 🎧🔊⚡

-## 🛡️ Dual-Driver Virtual Thermal Guards & Power Caps
-
-Because Linux cannot access the T2 hardware current-sensing ADCs, we implement a **Virtual Voice-Coil Thermal Model** that models continuous electrical power dissipation ($P = V_{\text{rms}}^2 / R_{\text{vc}}$) and exponential cooling into the air gap:
-
-$$C_{\text{th}} \frac{d\Delta T(t)}{dt} = \frac{V_{\text{rms}}^2(t)}{R_{\text{vc}}} - \frac{\Delta T(t)}{R_{\text{th}}}$$
-
-### Thermal Guard Configurations
-
-* **Woofer Thermal Guard (`thermal_guard` @ Post-`wlim`):**
-  * **Continuous Power Cap:** **$1.0\text{ W}$ ($1,000\text{ mW}$)** per channel ($16\%$ of max $6.25\text{ W}$ peak power).
-  * **Linear RMS Threshold (`al`):** `0.4000` ($-7.96\text{ dBFS}$ RMS).
-  * **Heating Tau ($\tau_{\text{heat}}$):** $2,500\text{ ms}$ (2.5 seconds).
-  * **Cooling Tau ($\tau_{\text{cool}}$):** $5,000\text{ ms}$ (5.0 seconds).
-* **Tweeter Thermal Guard (`tweeter_thermal_guard` @ Pre-`tlim`):**
-  * **Continuous Power Cap:** **$100\text{ mW}$ ($0.100\text{ W}$)** per channel ($1.6\%$ of max $6.25\text{ W}$ peak power).
-  * **Linear RMS Threshold (`al`):** `0.126491` ($-17.96\text{ dBFS}$ RMS).
-  * **Heating Tau ($\tau_{\text{heat}}$):** $1,000\text{ ms}$ (1.0 second).
-  * **Cooling Tau ($\tau_{\text{cool}}$):** $2,000\text{ ms}$ (2.0 seconds, fast decay recovery from Zoom/WebRTC glitches).
-
-> **Acoustic Result:** Dynamic music (Blues, Classical, Rock) has high crest factor ($12\text{ dB} - 18\text{ dB}$) and operates at $0\text{ dB}$ gain reduction with full peak dynamics. Continuous high-power signals (full-volume white noise or sine sweeps) are automatically attenuated to harmless power levels after ~2 seconds.
