SoundGarden — Touch-Driven Generative Soundscape Engine
Turn your iPhone into a living musical instrument. SoundGarden transforms every tap into a harmonically tuned sound that blooms, evolves, and fades away naturally — creating infinite, never-repeating ambient soundscapes from nothing but pure algorithmic synthesis.
TAP TO PLANT SOUNDS
Touch anywhere on the dark canvas to plant a glowing sonic seed. Each tap position matters — left-to-right controls pitch (low to high), top-to-bottom controls loudness. Every note is automatically tuned to your chosen musical scale, so everything sounds beautiful together. Watch as a note name appears above each element, showing you what you've just created.
6 WAVEFORM VOICES
Choose from six distinct synthesis engines before you tap:
• Sine — Pure, crystalline tones
• Triangle — Warm, mellow textures
• Sawtooth — Bright, buzzing harmonics
• Square — Hollow, reedy character
• Noise — Atmospheric, granular washes
• FM Synth — Complex, morphing timbres with evolving modulation
8 MUSICAL SCALES × 12 KEYS
Select from Pentatonic Minor (meditative), Pentatonic Major (uplifting), Lydian (dreamy), Dorian (jazzy), Mixolydian (warm), Natural Minor (emotional), Whole Tone (ethereal), or Chromatic (free). Pair any scale with any root note from C through B. Every sound you create is quantized to your chosen tonality.
INTELLIGENT AUTO-COMPOSE MODE
Tap the Auto button and let the generative engine compose for you. Powered by second-order Markov chains and Brownian motion, it creates musical phrases of 2–5 notes, pauses to breathe, then composes another phrase — mimicking the ebb and flow of real ambient music. Adjust Tempo and Complexity to shape the composition from sparse, meditative drones to dense, evolving textures.
STUDIO-QUALITY EFFECTS
Shape your soundscape with real-time effects:
• Reverb — From intimate room to vast cathedral
• Delay — Echoing repeats with adjustable timing
• Drift — Organic frequency wandering for living textures
• Master Volume — with soft-clip saturation for warmth
LIVING VISUALS
Every sound is a glowing orb that pulses with the music. A 32-band spectrum analyzer paints the bottom of the screen with reactive color. Sounds naturally fade in, sustain, then gracefully dissolve — up to 12 simultaneous voices that the canvas manages automatically.
FULLY PRIVATE. FULLY OFFLINE.
No internet connection needed — ever. No accounts. No data collection. No subscriptions. No samples or sound files — everything is generated mathematically in real-time on your device using pure audio synthesis.
Perfect for meditation, focus, sleep, creative inspiration, sound design exploration, or simply the joy of sculpting sound with your hands.
