Shruti Box - Digital Indian Drone & Sound Sanctuary

🧘 Reconnect with the Sacred Drone

ŚrutiBox is a high-performance, microtonal PWA drone instrument that maps a traditional 3-octave acoustic reed setup onto a responsive 39-key interface. Designed for classic Indian vocal practice, raga exploration, ambient composition, and sound meditation, it moves past static electronic tones to recreate the organic warmth, air movement, and resonant wood body of a physical hand-pumped bellows instrument.

✨ Core Tuning & Acoustic Systems

• 3 Full Octaves (39 Keys) 🎹: Complete freedom to construct rich chord foundations across low, middle, and high registers using natural Indian notation.
• True Just Intonation 🧪: Tuned according to the acoustic perfection of the traditional 22-śruti system rather than Western equal temperament.
• Dual Reference Tuning 🎶: Seamlessly toggle between modern performance standard (440Hz) and alternative acoustic resonance (432Hz).
• Sa Key Shifting 🔄: Transpose the entire instrument up or down semitones to shift your tonic key while maintaining intuitive layout labels.

💨 Dynamics & Interface Customization

• Dynamic Bellows Engine 🌀: Real-time "Force" slider controlling air pressure, organic amplitude modulation, and physical reed saturation.
• 4 Custom Skins 🎨: Instantly swap between Classic Mahogany Wood, modern Minimalist Paper, a late-night Night/Zen canvas, or a High-Visibility Contrast theme.
• Chord Presets & Memory Slots 💾: Quick-load traditional consonant foundations (Sa-Pa, Sa-Ma, Yaman, Bhairavi) or save up to 4 custom favorite drone arrays straight to browser memory.

📱 PWA Optimized & Mobile Ready

Built as a Progressive Web App, ŚrutiBox supports full offline capabilities, responsive multi-touch swipe mechanics, and home-screen installation. Experience professional-grade acoustic drone simulation directly in your browser with zero latency.
