I have created `master_strip_gui.html` containing both the Markdown visual description and the full HTML5 implementation of the Master Strip console.
|
||||
|
||||
### Summary of What Was Created:
|
||||
1. **Markdown Documentation Section**:
|
||||
* **Signal Flow**: Detailing the `Source -> Main Out Slider (Gain) -> Analyser -> Destination` post-fader audio path.
|
||||
* **Component Layout Breakdown**: Detailing the top routing header, dual stereo VU meters, narrow vertical fader, right-hand button stack, and RMS readout footer.
|
||||
2. **HTML5 Implementation**:
|
||||
* **Dual Stereo VU Meter**: Canvas-based visualizer featuring L/R channels with dB markings on both sides (`+12` to `-54 dB`).
|
||||
* **Post-Fader Audio Engine**: AudioContext graph with live sine/kick test generator responding dynamically to slider and mastering panel controls.

## 2. Audio Processing Graph & Wiring (Web Audio API)
|
||||
|
||||
Audio signals passing through the Track Channel Strip follow a serial processing chain (*Post-FX Signal Path*):
|
||||
|
||||
$$\text{Input Source} \xrightarrow{\quad} \text{Phase Invert ($\text{\O}$)} \xrightarrow{\quad} \text{Track FX Chain} \xrightarrow{\quad} \text{Mute / Solo Switch} \xrightarrow{\quad} \text{Volume Fader (Gain)} \xrightarrow{\quad} \text{Stereo Panner} \xrightarrow{\quad} \text{Analyser (VU Meter)} \xrightarrow{\quad} \text{Master Bus}$$
|
||||
|
||||
* **Phase Invert ($\text{\O}$):** Inverts the signal phase by $180^\circ$ ($G = -1$) to resolve phase cancellation issues between multiple microphone inputs.
|
||||
* **Track FX Chain:** Dedicated track insertion effects (Dynamic EQ, Reverb, Delay).
|
||||
* **Mute / Solo Logic:**
|
||||
* **Mute [M]:** Sets Linear Gain = $0.0$.
|
||||
* **Solo [S]:** Silences all other non-soloed tracks across the session.
|
||||
|
||||
|
||||
* **Volume Fader Scaling:** Converts decibels ($\text{dB}$) from the fader position into a linear gain factor $G$:
|
||||
|
||||
$$G = 10^{\frac{\text{dB}}{20}}$$
|
||||
|
||||
|
||||
|
||||
*(Control range: $-60\text{ dB}$ to $+12\text{ dB}$)*.
|
||||
* **Stereo Panner:** Adjusts spatial positioning across the stereo field from Left ($-1.0$) to Right ($+1.0$).
|
||||
* **Peak VU Metering:** An `AnalyserNode` extracts real-time amplitude data to render a dynamic LED meter (Green $\to$ Yellow $\to$ Red).
|
||||
|
||||
---
|
||||
|
||||
## 3. Practical Track Channel Applications
|
||||
|
||||
* **Mixer Dock Rendering:** Iterates and renders a strip for each item in `session.tracks` along the docked Mixer Console at the bottom of the screen.
|
||||
* **Color Accent Synchronization:** Accent bars at the top and bottom (`topColorBar` and `bottomFooterBar`) match the assigned track identification color on the main Timeline.
|
||||
* **Live Recording (ARM 🔴):** Toggling the ARM button prepares the channel to receive real-time input from a live microphone or hardware MIDI keyboard.
