Soulwhistle

An open-source platform for consciousness research using precise audio and radio frequency generation.

Soulwhistle is a real-time audio synthesis engine designed for researchers, practitioners, and developers working with brainwave entrainment, binaural beats, and consciousness exploration. Generate custom frequencies, design multi-phase sessions, and integrate with research hardware.

Core Capabilities

Audio Synthesis

• Binaural Beats: Any frequency from 0.1 to 30 Hz (delta, theta, alpha, beta, gamma)
• Custom Carriers: Configurable carrier frequencies (optimal range: 300-600 Hz)
• Multi-Layer Mixing: Schumann resonance (7.83 Hz), harmonics (528 Hz), ambient pads (432 Hz)
• Signal Types: Sine, triangle, square, sawtooth, FM/AM modulation, organic chirps
• Session Phases: Multi-phase sessions with independent beat frequencies per phase

Research Features

• Real-Time Control: Live adjustment of frequencies, volumes, and waveforms via TUI
• Network Streaming: HTTP audio streaming for wireless playback (experimental)
• RF Transmission: HackRF One integration for radio frequency experiments
• Preset System: JSON-based presets for reproducible experiments

Example Applications

• Brainwave entrainment studies
• Meditation and focus enhancement
• Sleep research (delta/theta transitions)
• Consciousness state exploration
• Custom therapeutic protocols

Getting Started

Installation

Option 1: Install from crates.io (recommended)

cargo install soulwhistle
soulwhistle

Option 2: Build from source

# Clone repository
git clone https://github.com/soulwhistle-project/soulwhistle
cd soulwhistle

# Build and install
cargo install --path .

# Or just build
cargo build --release
./target/release/soulwhistle

Presets are automatically installed to:

• Linux: ~/.config/soulwhistle/presets/
• macOS: ~/Library/Application Support/soulwhistle/presets/
• Windows: %APPDATA%\soulwhistle\presets\

Quick Start

1. Select a preset: Use p key to browse included research presets
2. Adjust parameters: Navigate with arrow keys, adjust with left/right arrows
3. Control playback: Space to play/pause, m to toggle oscillator types
4. Lock signal layer: x to lock/unlock core frequencies during experimentation

Basic Controls

Key	Action
↑/↓	Navigate channels
←/→	Adjust values
Space	Play/pause
m	Mute/unmute channel
o	Cycle oscillator type
p	Select preset
x	Lock/unlock signal layer
c	Collapse/expand sections
q	Quit

Research Presets

Soulwhistle includes presets based on peer-reviewed research and established protocols. Experimental presets (clearly marked with [EXPERIMENTAL] in the UI) are exploratory and not peer-reviewed.

General Focus & Meditation

• Deep Focus (Active): Beta/low-gamma for concentration (12-15 Hz)
• Deep Focus (Calm): Alpha/theta for relaxed focus (8-10 Hz)
• Deep Focus (ADHD): Optimized beta protocol for ADHD research
• Deep Focus (Peak): High beta/gamma for peak performance (18-25 Hz)

Monroe Institute-Derived Examples

These presets are based on independent FFT analysis of Monroe Institute techniques:

• Focus 10: "Mind awake, body asleep" state (alpha/theta transition)
• Focus 12: Expanded awareness state (theta with gamma bursts)
• Focus 15: "No-time" state (deep theta)
• Focus 21: Bridge state (complex multi-frequency)

Animal Research

Ultrasonic and RF frequencies for behavioral research across multiple species (dogs 23-54 kHz, cats up to 79 kHz, rodents 30-110 kHz, marine mammals up to 160 kHz, bats 20-80 kHz).

UAP Contact Research (Experimental)

RESEARCH TOOLS ONLY - NO CLAIMS MADE

These presets implement frequency combinations from anecdotal UAP research community reports. We provide these tools for independent experimentation only.

• UAP Frequencies: Multi-layered signal based on anecdotal reports
• UAP Enigmatic Ideas: Anecdotal implementation (100 Hz carrier AM @ 7.83 Hz)
• UAP Brycehelm: Bryce Helm's design (783 Hz carrier AM @ 7.83 Hz) - github.com/brycehelm/UAP_Dog_Whistle
• UAP Sweep 18kHz: UAPWatchers guide variant (requires piezo transducers or RF mode)
• UAP Sweep 24kHz: Extended ultrasonic sweep (requires RF transmission mode)
• UAP RF Ultrasonic: Anecdotal electromagnetic approach at 1.42 GHz Hydrogen Line (HackRF required)

Important:

• No scientific validation exists for UAP contact via audio/RF frequencies
• RF transmission requires appropriate licenses and legal authorization
• See research/UAP_VARIANTS.md for full documentation and legal warnings
• The term "dog whistle" in UAP communities refers to electromagnetic signaling devices, unrelated to animal research

Other Experimental

These presets are exploratory and not based on peer-reviewed research:

• Explore All: Scans through all brainwave states sequentially

Contributing Research Presets

We welcome contributions of research-based binaural beat protocols!

Preset Creator Skill

Soulwhistle includes a Claude Code skill (.claude/skills/preset-creator/) with:

• Peer-reviewed binaural beat research knowledge
• Optimal carrier frequency guidelines (300-600 Hz)
• Multi-phase session design patterns
• Safety guidelines and contraindications

Contribution Requirements

All preset submissions must:

• ✅ Be grounded in peer-reviewed research OR clearly marked as experimental ("experimental": true)
• ✅ Include proper citations (research presets) or rationale (experimental presets) in the description
• ✅ Follow optimal carrier frequency guidelines
• ✅ Include safety warnings and contraindications
• ✅ Specify target use case and session duration

➡️ Full contribution guide in CONTRIBUTING.md

OpenBCI Integration (Planned)

A primary goal is to integrate with OpenBCI hardware for closed-loop brainwave entrainment research. This would enable:

• Real-time EEG monitoring during sessions
• Automatic frequency adjustment based on brain state
• Data correlation between stimulus and response
• Reproducible experimental protocols

Pull requests for OpenBCI integration are highly encouraged!

Network Streaming (Experimental)

HTTP audio streaming allows wireless playback to VLC or other clients:

# In Soulwhistle UI
1. Navigate to NETWORK STREAMING section
2. Enable streaming (Space key)
3. Optionally adjust port (default: 1123)

# On client device
vlc http://<soulwhistle-ip>:1123/stream.wav

Help Wanted: This feature needs contributions for improved protocols, buffering, multi-client support, and documentation.

Architecture

• Rust: High-performance real-time audio synthesis
• CPAL: Cross-platform audio output
• TUI: Real-time interactive mixer interface
• HackRF: Optional RF transmission support
• JSON Presets: Reproducible session configurations
