Dsp / audio analytics consultant (gunshot/impact/vape fusion) — part-time
6 days ago
Location : Hyderabad, IndiaAbout the engagementOur 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 doSelect 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.Must-have5+ years DSP/audio ML (torchaudio/librosa), real-time classification on edge hardware.Model deployment experience (ONNX/Tensor RT where relevant), streaming pipelines, latency profiling.Practical know-how with noisy environments (reverberation, HVAC, impulse sounds, crowd noise).Nice-to-haveExperience with public audio model families (e.g., PANNs-style architectures) and license vetting.Mic placement, array processing (GCC-PHAT, beamforming), AEC/denoise familiarity.Timeseries analytics (onset/peak detectors) and event synchronization.Deliverables (first 4–6 weeks)Audio model + preprocessing config achieving target precision/recall on our clips; latency budget & CPU/GPU load report.Zone-wise threshold table, Δt gates, and privacy policy notes (bathroom handling).Test suite + confusion matrix and a simple monitoring dashboard for false-alarm drift.Selection Criteria:· Live/Whiteboard/IDE (90-120 min) around Acoustic event design, Thresholds & zone gating, Sensor fusion windowing, Mic placement & future TDOA and Edge deployment· Take-Home (Next steps : If interested please email your cover letter and resume toAshwin at
