DSP / Audio Analytics Consultant (Gunshot / Impact / Vape Fusion) — Part-Time

Location : Hyderabad, India

About the engagement

Our campuses include mics and vape sensors (bathrooms = audio / vape only, no video). We need an audio expert to deliver low-latency acoustic anomaly detection (gunshot / impact / shout) and to define sensor-fusion timing with optical events.

Time : 4–8 hrs / week (flex). Location : Remote.

What you’ll do

• Select and adapt edge-friendly audio models for gunshot / impact / shout (Apache-friendly where possible) and define thresholds per zone.
• Engineer robust preprocessing : resampling, VAD, log-mel / spec features, clipping / AGC handling, channel calibration.
• Define ±Δt gating vs. optical events; handle device offsets and publish evidence (onset time, spectral signature).
• If applicable, design mic-array / TDOA roadmap (future) : array geometry, beamforming options, calibration SOP.
• Build an evaluation set (curated clips + confusers) and scorecards; tune for low false alarms.
