How In-Browser Drum Synthesis Works (Web Audio DSP)
Unlike traditional web instruments that rely on megabytes of pre-recorded audio samples, this drum machine generates every transient, fundamental tone, and decay tail using mathematical sound synthesis in real-time through the browser's Web Audio API.
A pure sine wave oscillator initialized at 150 Hz that exponentially sweeps downwards to 30 Hz in ~120 milliseconds. This rapid pitch drop mimics the physical attack impact of a beater hitting a taut drum skin.
A combination of dual audio nodes: a resonant low-frequency body oscillator combined with a 2-second white noise buffer routed through highpass and bandpass biquad filters to simulate wire rattles and metallic shimmer.
Because there are zero external MP3 or WAV network requests, latency is constrained strictly to the hardware buffer size (~5ms), ensuring responsive live jamming without perceived lag or stutter.
