Interactive DSP testbed for wearable speech isolation, wind reduction, beamforming spatial filters, and ambient acoustic event monitoring.
Modern smartwatches leverage dual or tri-microphone arrays. By computing the arrival-time delay (interaural time difference) between microphones, spatial nulls cancel sounds arriving outside a tight directional cone facing your mouth.
High velocity wind generates non-acoustic turbulent pressure fluctuations below 250 Hz that saturate microphone diaphragms. Neural intelligence combines multi-order high-pass filtering with dynamic spectral gating to preserve speech fundamentals.
While voice isolation removes background clutter for phone calls and voice memos, wearable safety systems continuously scan raw environmental audio for critical acoustic alerts—like car horns, sirens, or alarm bells—to alert the user.
