RESEARCH & LEARNING VAULT // Granular Synthesis & Micro-Acoustics

Hanning window envelopes, stochastic pitch spray, and buffer time-stretching.

ACADEMIC & ALGORITHMIC REFERENCE

// HISTORICAL ORIGINS

Pioneered in acoustic music by composer Iannis Xenakis (1971) and computer music pioneer Curtis Roads (1978).

// GOVERNING EQUATIONS

w(t) = \frac{1}{2} \left(1 - \cos\left(\frac{2\pi t}{D}\right)\right)

// BROWSER IMPLEMENTATION

Extracts short overlapping PCM audio grains (15ms to 250ms), applies raised-cosine windowing, and plays grains with randomized stereo pan and pitch rates.

// GUIDED EXPERIMENTS TO TRY IN THIS SANDBOXNORMAL

1Ambient Shimmer Cloud

🎯 Action:Load 'Crystal Bells', set Grain Duration to 180ms, Density to 60/sec, and Pitch Spray to 0.8.

✨ Observe:Deconstruct crisp bell strikes into an ethereal, shimmering ambient cloud.
