Angin lembut — Inner Peace, original project synthesis. No third-party recording or recording license is claimed. v2.0.7: 24-second periodic filtered noise, deterministic seed 207, lowpass 440 Hz, gentle periodic modulation. Lossless PCM16 mono WAV at 22050 Hz. No fade-to-silence at the boundary, no MP3 encoder padding. Decoded once, then a 0.5-second equal-power overlap removes decoder/resampler edge padding. The prepared 23.5-second buffer repeats with sample-accurate WebAudio AudioBufferSourceNode looping. The locally synthesized soft bell uses 196/403/573/825/1085 Hz partials and natural decays.
