- **Multiple Exit Methods**: Ctrl+C, Escape key, or threshold trigger
- **Smooth Visual Updates**: 10ms refresh rate with exponential smoothing
- **Cross-platform**: Works on macOS, Linux, and Windows
- **Terminal UI**: Beautiful text-based interface using Ratatui

## Usage 📖

### Basic Usage

```bash
# Monitor with default settings (-20 dB threshold)
soundcheck

# Set custom threshold
soundcheck --threshold -30

# Specify audio device
soundcheck --device "MacBook Pro Microphone"

# Combine options
soundcheck --threshold -25 --device "External USB Audio"
```

### Command Line Options

| Option        | Description                      | Default        | Example                     |
| ------------- | -------------------------------- | -------------- | --------------------------- |
| `--threshold` | Audio threshold in dB (-60 to 0) | -20            | `--threshold -30`           |
| `--device`    | Audio input device name          | Default device | `--device "USB Microphone"` |

### Command Chaining Examples

```bash
# Continue to next command only if threshold reached
soundcheck && echo "Audio detected!"

# Run fallback command if user exits
soundcheck || echo "Monitoring cancelled by user"

# Error handling
soundcheck || echo "Failed to start monitoring"
```

## Requirements 📋

### System Requirements

- **macOS**: 10.15 or later
- **Linux**: Kernel 3.16+ with ALSA
- **Windows**: Windows 10+ with WASAPI

### Audio Hardware

- Audio input device (microphone, line-in, etc.)
- Proper audio permissions (especially on macOS)

### Dependencies

- **Rust**: 1.70+ (for edition 2021)
- **Audio Libraries**: System audio frameworks
  - macOS: CoreAudio
  - Linux: ALSA
  - Windows: WASAPI

## Configuration ⚙️

### Audio Device Selection

```bash
# List available devices (if supported by your audio library)
# Then specify the device name
standby --device "External Microphone (USB)"
```

### Threshold Tuning

- **Quiet environments**: -30 to -40 dB
- **Normal conversation**: -20 to -25 dB
- **Loud music/events**: -10 to -15 dB

## Development 🛠️

### Building

```bash
# Debug build
cargo build

# Release build
cargo build --release

# Run tests
cargo test

# Check code quality
cargo clippy
cargo fmt
```

## Troubleshooting 🔍

### Common Issues

**"No default input device"**

- Ensure your microphone/audio input is connected and enabled
- Check system audio settings

**"Device not found"**

- Use `soundcheck --help` to see available options
- Verify the device name spelling

**Blank screen on startup**

- Ensure terminal supports Unicode characters
- Try a different terminal emulator

**Audio levels not updating**

- Check that the correct audio device is selected
- Verify audio input permissions
- Test with different threshold values

### Debug Mode

```bash
# Run with verbose output
RUST_LOG=debug cargo run -- --threshold -20
```
