Design

Capsule features a modern macOS UI built entirely with SwiftUI:

• Thick Pill Sliders: Custom-designed volume sliders with a distinctive pill shape
• Frosted Glass Background: Native NSVisualEffectView for that authentic macOS look
• SF Symbols: System icons that automatically adapt to your macOS appearance
• Smooth Interactions: Drag to adjust volume, double-tap to mute

Requirements

• macOS 13.0 (Ventura) or later
• Xcode 15.0 or later (for building)

Building

1. Clone the repository:

   git clone https://github.com/sp80808/capsule.git
   cd capsule

2. Open in Xcode:

   open Capsule.xcodeproj

3. Build and run (⌘R)

Architecture

The app is structured with clean separation of concerns:

• CapsuleApp.swift: Main app entry point and delegate
• ContentView.swift: Main UI with frosted glass and app list
• PillSlider.swift: Custom pill-shaped slider component
• AudioManager.swift: Core Audio integration for audio device management

Audio Integration

The current implementation includes:

• Core Audio framework integration for device enumeration
• Foundation for per-app audio tapping (ready for eqMac driver integration)
• Sample app data for UI demonstration

Future Enhancements

To integrate with eqMac driver for actual per-app audio tapping:

1. Install and configure the eqMac audio driver
2. Implement audio session capture per application
3. Hook up volume controls to actual audio streams
4. Add real-time audio level visualization

Usage

• Adjust Volume: Drag the pill slider left or right
• Mute/Unmute: Double-tap on a slider
• Refresh Apps: Click the refresh button in the header
