# Camouflage

> Ultrasonic audio jamming tool to protect against unauthorized recording

[![Made by Nomi](https://img.shields.io/badge/Made%20by-Nomi-blue)](https://www.nomi.so)

Camouflage generates ultrasonic signals (20-24kHz) that interfere with audio recording devices while remaining inaudible to humans. It operates in two distinct modes:

## Features

- **Speaker Jammer Mode**: Outputs ultrasonic signals through speakers to jam nearby microphones
- **System Jammer Mode**: Creates virtual audio devices to prevent remote recording during voice calls
- **Multi-tone Generation**: Uses multiple ultrasonic frequencies for increased effectiveness
- **Inaudible Operation**: Optimized amplitude settings to remain completely inaudible
- **Cross-platform Support**: macOS, Linux, and Windows (platform-specific features vary)

## Installation

### Docker

```bash
docker pull nomiswan/nomi.so:latest
docker run nomiswan/nomi.so speaker
```

### From Source

```bash
cargo build --release
./target/release/camouflage speaker
```

## Usage

### Speaker Jammer Mode

```bash
# Run with default settings
camouflage speaker

# Custom frequency and amplitude
camouflage speaker -f 23000 -a 0.3

# Multi-tone jamming
camouflage speaker -n 5 -s 500
```

### System Jammer Mode

```bash
# Run with default settings
camouflage system

# Custom mix ratio
camouflage system -m 0.5
```

## Performance

Tested against commercial STT services:
- **OpenAI Whisper**: 95%+ jamming effectiveness
- **Deepgram**: 90%+ jamming effectiveness
- **CPU Usage**: <5% on modern hardware
- **Latency**: <10ms in system mode
