Students, professionals, meditation practitioners, sleep seekers, travelers, and sound designers.

**Binaural Beats - Science Meets Serenity**
Experience brainwave entrainment with our advanced binaural beats generator. Choose from presets optimized for:
- **Deep Sleep** (Delta: 2-3 Hz) - Restorative rest and healing
- **Meditation** (Theta: 4-8 Hz) - Deep relaxation and creativity
- **Relaxed Focus** (Alpha: 8-13 Hz) - Calm alertness and stress relief
- **Active Concentration** (Beta: 13-30 Hz) - Study and problem-solving
- **Peak Performance** (Gamma: 30+ Hz) - Memory and cognitive enhancement
- **Travel** - Optimized for airplane journeys

Layer Pink or Brown noise to mask distractions. All presets are based on decades of neuroscience research. Headphones required.

**Professional Noise Generation**
Twelve distinct noise types with unique characteristics:
- **Pink** - Natural, balanced (-3dB/octave) - Perfect for sleep
- **White** - Equal energy at all frequencies - Ideal for masking
- **Brown** - Deep bass (-6dB/octave) - Blocks low-frequency noise
- **Blue** - Bright, crisp (+3dB/octave) - High-frequency emphasis
- **Violet** - Very bright (+6dB/octave) - Strong high-frequency emphasis
- **Gray** - Perceptually equal loudness (ISO 226:2003)
- **Green** - Mid-range focused (-1.5dB/octave)
- **Orange** - Anti-harmonic structure
- **Brown-Pink Hybrid** - Median slope (-4.5dB/octave)
- **Stereo ID** - Automated speaker identification sequence for testing and calibration

All noise generators use state-of-the-art algorithms for authentic, professional-quality sound.

**Pure Sine Wave Generator**
Generate precise tones from 20 Hz to 20 kHz with smooth logarithmic control. Features quick presets, keyboard navigation with arrow keys (1/20 octave precision), and ISO 1/3-octave band selection with automatic frequency snapping. Perfect for tuning, testing, and sound design.

**Sine Sweep & 3-Tone Generator**
Logarithmic sweeps for frequency response testing. Set start/end frequencies and duration with 3ms fade in/out. New 3-tone mode lets you configure three test tones with individual frequencies and durations (default: 100Hz, 800Hz, 6.4kHz at 500ms each, spaced 1 second apart).

**Professional Audio Controls**
Independent left/right volume faders with keyboard support (arrow keys for 5% precision), real-time peak and RMS level meters, stereo linking toggle, mono/stereo toggle switching, -12dBFS and -20dBFS reference levels, output device selection, and real-time processing at 44.1 kHz.

**Keyboard Shortcuts & Accessibility**
Arrow keys for precise frequency control (1/20 octave steps) and volume control (5% steps). Click any fader cap to focus it, then use arrow keys for precise adjustments. Tab navigation and full VoiceOver support.

**Built for Professionals**
AES-compliant pink noise, accurate frequency response curves, 44.1 kHz sample rate, zero-latency processing, and broadcast-standard reference levels.

**Perfect For:**
Meditation, study sessions, sleep improvement, creative audio production, sound design, travel noise masking, focus enhancement, and stress relief.

**Requirements**
Binaural beats require headphones. Works with any audio output device. Optimized for macOS with full accessibility support.
